Jump Chain 14 - Smallville

Part 7

Gotham. Alt DCAU.

It didn't take me long to find a version of the Batcave that I could get access to. In this version of the DCAU like in others, a rogue Amazon called Aresia, a version of which I'd already met, recruited a gang of super crooks as part of a scheme to wipe out the world's entire male population because she believed that dooming the human race would make things better for women everywhere. In this dimension she was successful and all the men were killed off.

The virus was gone now, having died off with its victims once its work was done, and this was good as while I was immune to all diseases, thanks to the Pureblood Perk I'd gotten during the Harry Potter Jump, I might still be able to serve as a host for the virus, which would lead to other people becoming infected should I somehow have spread the virus to other worlds.

I'd sent a probe first just to be on the safe side and then when no danger was detected I went into this alternate dimension and found myself underneath Wayne Manor in the Batcave. It was inside this cave that Bruce Wayne first assumed the mantle of the Bat. Making it a very historically significant location despite the fact that few people in this reality even knew it existed.

The Batcave served as a garage and mechanic's workshop for Batman's vehicles, a crime laboratory, a place to store his equipment (including the famous Batcomputer that I would soon check out) and a museum of sorts for various trophies he'd picked up during his adventures. Something I spent quite some time admiring.

This cave also featured a gymnasium and a high-tech obstacle course, to keep Batman and his associates in fighting condition. All of these things and more I found while wandering the underground space, out of phase, unseen by any security features.

I knew from my intelligence files that Batman designed the Batcave as a replica of the lair of the Gray Ghost, Bruce Wayne's childhood TV hero from the old television series. At least that was how it had started. It had grown from that idea into something greater.

Batman constructed at least three access points to the cave: A grandfather clock in the manor library concealed a flight of stone stairs leading down to the cave; A bookshelf in the library covered the entrance to a private elevator; A ramp concealed in the cliff face below the manor allowed the Batmobile to exit the cave and quickly make it to Gotham. There was also a means of allowing flying vehicles, such as the Batwing and/or the Fourth Batmobile, or aquatic vehicles, including the Batboat.

Batman, Robin, Batgirl, and Nightwing used the cave as the centre of their operations. It was here that they would be informed of the activities of Gotham's notorious criminals and develop their plans to deal with these threats. The Batmobile, Batboat, Batcycles, and Batwing were all housed within the cave, along with several other vehicles used by the group.

By far the most important tool was the massive computer they utilized for everything from chemical analysis to researching old newspapers for clues. At one point this computer was temporarily controlled by H.A.R.D.A.C., the rogue supercomputer, who attempted to use much of the advanced technology to kill Batman.

The Batcave served as a refuge for the Justice League during the Thanagarian invasion. A strike force led by a Thanagarian called Kragger breached the entrance (which he was able to find by placing a tracking device on Shayera Hol) in an attempt to catch the League off their guard. A fight ensued, with both sides making use of the various items displayed around here. Most notable among these was Kragger's attempt to subdue Superman using Mr Freeze's cold gun, only for Superman to simply blow the beam back at Kragger with his breath.

Within the cave, I found displays that included not only replicas of Batman's most famous enemies (both wax dummies and robot combat trainers), but also original or replicate costumes of infamous members of his rogues gallery, including Catwoman, Firefly, Harley Quinn, Killer Croc, Mad Hatter, Mr Freeze, Penguin, Riddler and Two-Face.

Other items that held my interest were Mr Freeze's freeze gun and headpiece, the puppet Scarface, a giant penny Batman received after an encounter with Two-Face, a large robotic Tyrannosaurus rex, an enlarged copy of the Joker's trademark joker cards, one of Roxy Rocket's rockets, all of which he was somehow able to get into the cave, Baby-Doll's doll-gun, as well as a full set of samurai armour and weapons that must be important for some reason.

I found a security vault, which I couldn't phase through for some reason and since Batman wouldn't use magic as a defence for the vault I could only conclude that he'd constructed the vault out of some special metal. When I came back to what could be considered normal existence I discovered that I was unable to use my X-ray vision to see inside the vault. However, I was able to punch my way inside while using my Kryptonian form, although it took some effort, and I triggered some alarms in the process. This didn't concern me too much as Batman wasn't around to deal with the alarm.

The vault turned out to be the armoury as well as a secure area for things Batman didn't want others to know about, such as several other versions of the Batsuit, each no doubt been designed for taking down certain foes. As I scanned I figured that the bulky suit that took up the most space was some sort of power armour for when the Dark Knight went up against super-strong metahumans.

There were many weapons in here. Few of which were lethal unless mishandled, but all were highly effective in Batman's hands. I found batarangs, gas bombs, telescoping staffs, Gauntlets with some nasty looking spikes on them, grapple guns and so much more.

Gotham's Grim Guardian was also hoarding kryptonite in case Superman ever went rogue again or to deal with other members of his race who might not be as noble as the Man of Steel. This made me glad that I'd invested in special shielding, but I changed to my Damien Mason form just be careful as the shielding didn't work if I made physical contact with the mineral.

There was some Green Kryptonite, which was the classic and most common form of kryptonite, this rock severely weakens Kryptonians, and can even kill them when exposed long enough. Also, there was some Red Kryptonite which effects were more varied than the green, my files told me that the stuff was known to cause bizarre mood swings and even mutations depending on which reality the stuff came from, or may depend on what universe the super-powered alien hero came from.

In smaller amounts, I found some Blue Kryptonite, which depowered Kryptonians but only while they, well we, were close to it. Batman even had Gold Kryptonite. This rare form of the mineral would destroy a Kryptonian's ability to process yellow sunlight, thus permanently removing their superpowers. It was not otherwise harmful to Kryptonian life. The Caped Crusader had fashioned some of the golden mineral into a knife, which I took along with anything else of value.

I even found some White Kryptonite, a version of the odd mineral that killed all plant life, regardless of origin, something to use against Poison Ivy I suspected. As well as small amounts of Silver Kryptonite, that induced hallucinations for Kryptonitions. Pink Kryptonite, which could temporarily turn my Kryptonition form gay if I touched it.

Since I knew that someone would respond to the alarm sooner or later as the female superheroes still existed in this world I packed up everything I could into a capsule, but not before wondering what the hell Purple Kryptonite did because while the small lead box containing it was labelled there was no mention of what it did. Perhaps the Batcomputer could tell me.

While the device was very advanced it was more than matched by Cortana who was able to hack into the system and disabled the alarms. I learned quickly that the Batcomputer would automatically update information on the cave's schematics, security and entrances as did so for me, letting me know that my looting of the secure vault had been noted.

I did find out about the purple space rock. It had the properties of Gemstone kryptonite in the Smallville show in that it granted the power of hypnotic persuasion to Kryptonians enabling them to verbally compel others to obey their commands.

It was speculated by Batman that what he called Purple Kryptonite might force even a Kryptonian to obey the commands of another Kryptonian. Meaning that Superman could use it to force other members of his race to be good guys. Batman had never experimented with this due to the dangers involved and because he didn't want to override anyone's free will.

Once I'd gotten the files I considered taking more, such as the cars and the trophies, but I decided against it, knowing that Batman would have data on all his toys stored in his databanks, and that with my tech I could improve upon his stuff if I chose to recreate any of it. Once the priceless information had been downloaded I prepared to leave, as this had only meant to be a quick raid, only something attacked me from the shadows.

A female form leapt out from the darkness with the intent of kicking me in the head only I was too quick for her and the agile woman ended up going right over me. Not that this slowed her down much because as soon as she touched the ground in a roll she was up again and charging right at me.

The customed hero, who just had to be Batgirl, attacked me with a flurry of kicks and punches, meant to take me down hard and fast. The moves would have worked if not for the fact that I had combat training of my own and the Force to guide my actions.

I used the Force to slam the redhead into the Batmobile, and while this barely phased her, it did give us the chance to make eye contact, and when we did she stopping fighting right away. I was not surprised by this as I'd figured out how an encounter with a superheroine of this world would work out. I knew that once they realised they were dealing with a human male that they'd cease fighting and try to suss out where I'd come from.

"You're a guy!" Batgirl yelled.

Normally a rather obvious statement and not worthy of notice, only in this world she'd have not seen a living human male for some time since they'd all died of a deadly disease.

"Yes I am the proud owner of a penis," I said with a smirk.

Which of course she tried to check out, and this could have given a chance to escape, but there was no need for that as I now no longer needed to escape. Well I might still want to run for it, but not for the same reasons as before as when Batgirl next came at me, it wasn't violence she had in mind.

Before I knew what was happening she had her powerful legs wrapped around me and was driving her tongue down my throat. I held on to her while trying to stay standing upright. Only that didn't last for long as the crime fighter soon had me pinned to the group, but not so that she could cuff me, although I felt certain she'd enjoy doing that, for now, she was more interested in humping my body.

Lucky for her this body wasn't wearing armour at the moment it was still dressed in the business suit I'd worn when meeting with the version of Lux Luthor who lived in that castle in Smallville. Since my alternate forms stayed equipped in whatever it was I'd be wearing when I'd last been in that form, and because of the Evercleansed body mod, which always kept me shower fresh, the suit still looked good on me and I thought that was playing its part in Batgirl trying to rap me.

"I haven't given my consent!" I yelled.

Batgirl gave me a puzzled look and stopped trying to dry hump me to an orgasm. It was as if the poor young woman couldn't comprehend the idea that I didn't want her to use me as a living sex toy. But she did stop.

"Oh go on then," I said, giving in.

Clearly some primal part of her brain had taken over because despite not knowing anything about me other than I was some guy who'd broken into the Batcave, she looked ready to make babies with me. Not that this was a concern as I took highly advanced birth control.

By now Batgirl had taken off her cowl. Hers was attached to her top so it was pulled back behind her. Her eyes were closed and her hair was unkempt, damp with sweat, she must have raced back to the cave when the alarm went off. Impressive considering that the alarms had gone off for that long.

Not that she cared about that as she'd started riding my cock, having gotten fed up with the dry humping already. Batgirl's cunt felt so tight around my dick as she rode me while I laid down on the cold floor of the Batcave. Despite the cold hard floor, and the fact that Barbara Gordan was basically using me as dildo on legs I felt fairly certain that were millions of nerds out there in the multiverse who would kill to be in my place.

Batgirl, for her part, seemed to be loving it. She'd pulled up her suit top and removed her bra, so that her breasts were free and she was holding them in her hands, occasionally rubbing one or both nipples. They bounced when she moved on top of me.

Given how dark it was, and that Batgirl wasn't going to get off me anytime soon all I could do was lie here and let her feel some pleasure. Okay so I could stop her in many different ways, but I'd decided to let her have her fun and I even used my powers to make this situation feel even better for her. Not for her sake I just figured that it would be easier to make deals with her in the future, and what other organisations existed within in this world that she was connected to, if Batgirl was sexually satisfied and therefore able to think more clearly.

My penis seemed to agree with this plan as just when she started to slow down, running out of steam, I orgasmed and I could feel the spurts of his cum going upside inside a very grateful sounding Batgirl. Once I was done she slowly pulled herself off me and I saw my cum begin trickle-down Batgirl's inner thigh.

She went and collapsed over the Batmobile, more from emotional turmoil than physical, and she laid there for what felt like a long time, seemingly lost in a daze. I got dressed and admired Miss Gordan's ass from close up.

"So my name is Gothic," I said, "I'm a visitor from an alternate dimension".

The response I got sounded more like something that would come from the mouth of a zombie rather than a healthy young woman so I decided to give her a little more time to recover.

Gotham. Alt DCAU.

"So now that I'm done acting like the world's biggest slut," said Batgirl as we left the Batcave and entered Wayne Manor "Maybe you'd be so kind as to explain what you were doing with Batman's stuff?".

That was a fair question.

"Like I already told you I'm a dimensional traveller," I told Barbara Gordan "and I knew that in this universe there would be no Batman so I figured it would be okay to loot the cave".

Batgirl, who'd not bothered to cover her face, tensed up upon hearing that, but took no action against me. She wouldn't want to risk harming me since I was a healthy human male in a world that lacked any of those.

"You don't need to be alarmed" I assured her "I mean no harm to this world or the people in it. I'm an explorer, not a villain, and I can help you".

Miss Gordan wasn't foolish enough to simply trust some stranger who she'd found messing about under what must be her home since she was the only member of the Batclan still alive, but she was also smart enough to realise that I could be means of saving her entire world if the situation was handled right.

"I think having one guy around might do more harm than good" Batgirl stated, "A lot of countries collapsed after the men all died, but there are plenty of nations and groups out there who'd kill to possess you".

Yes, by myself I wasn't much help, but I was thinking in bigger terms.

"I can travel to different dimensions at will" I explained while creating a portal back to Lux just to show that I c could "So it won't be too much trouble for me to bring healthy human males to this planet. I'd need the League to take custody of anyone I sent here to make sure they aren't mistreated and that they go where they need to".

Batgirl considered this after taking a look at the portal I'd made. Which of course I didn't leave open for too long.

"We'd need thousands of men. At least," she said, "Where would you get them from?".

I already had this planned out. I'd known that sooner or later I'd get caught while looting in this dimension, it had just happened sooner than expected, and so I'd figured that rather than try to fight my way free that I could just offer a deal so as to turn a potential enemy into a valuable ally.

"You'd need tens of thousands" I informed Batgirl "I wouldn't deliver them all at once as you'd need to set up secure housing for them, along with medical staff, therapists, security, support staff to feed and clothe them, and so. If you've inherited Bruce Wayne's wealth and properties than you should be able to help me arrange that".

I had more to say, and that was good because I wanted to keep Batgirl distracted from the fact that I'd somewhat looted the Batcave.

"As for where I get the men from, that's the easy part" I was now saying "Back home there must hundreds of thousands of homeless people in North America alone. Even filtering out those who are women, too old, too sick, or not mentally stable enough there must be tens of thousands of youngish men in North America who wouldn't mind a chance to start over somewhere else. Then there are refugees and immigrants. If I start up a charity back home to help care for the dispossessed I can screen for healthy candidates to send here. With their consent and no one will care enough about what happens to them to try to find out where they vanished if anyone ever notices anything at all".

Padme would get behind this idea as it would allow her to help the people of two worlds.

"That will take time to sort out, in short term I can buy a sperm bank back home and buy samples from healthy donors for you" I offered "and that's not even counting the other dimensions. There could be survivors out there on versions of Earth that have been nearly totally destroyed that we could resettle here if you can find room for them".

At this point, Batgirl looked more amazed than she had during the sex. Which was really saying something.

"I think we need to talk to the League" she decided "This is too much for me to handle on my own".

Yes, I should talk to the big guns as this project was going to need a lot of coordination on both sides. On my side, it wouldn't be too much work as in the version of Metropolis I called home, at least when living at Lux, there had to be suitable properties to serve as a headquarters for a homeless charity within the city and plenty of homeless around to screen genetically to see if they'd be suitable candidates.

"Good idea" I agreed "Let's go talk to your League".

With the male founding members dead it would be interesting to see who was in charge of this group and while allying with 2 versions of the DCAU Justice League might seem like a drain on my time as well as resources it wouldn't be as long as it was managed well.

The North Pole. Alt DCAU.

The Fortress of Solitude was Superman's private hideaway and the last part of Krypton to exist past the planet's demise. Over time Superman expanded the fortress to include a control room, a hall of weapons, a massive menagerie that housed animals from alien worlds, and various trophies from his previous adventures.

There was also a giant ice sculpture of Superman's biological mother and father, created by him as a memorial. I was looking at it right now. Besides the aforementioned decorative features, the Fortress of Solitude contained the necessary facilities and equipment to build android doubles of Superman to address crises, should Superman himself be unavailable for whatever reason.

"So what did you want to show me?" I asked.

I was taking a break from the negotiations with the all-female Justice League of this world that would involve them taking custody of the healthy human males my group would be sending to this universe as part of a project to prevent the human race from going the way of the dinosaurs.

As I'd know Padme was rather thrilled with the idea and would work on my group's end of things without needing me to get involved much. Most of my effect would involve setting up the equipment to screen candidates and if needs be, removing any genetic disorders from the men so their offspring wouldn't inherit any flaws. I had no intention of making a race of superhumans, but my technology could lead to a version of humanity with far fewer medical problems.

It would take years to find enough men to give this world a good breeding population, but most of the hard work would be done in this world and I had plenty of companions these days to help out. If they did need more help I could build some fembots and have them handle most of the work.

"This is what I wanted you to see," said the local version of Supergirl.

Either because she'd gotten older or because she'd decided to step up and try to serve the role for the world that Superman had, this version of the Maid of Might wore a female version of Superman's uniform. She wore a shirt and short cape, but other than that it was more or less the same outfit.

The two of us had gotten chatting during the talks, and after I'd shown her my Jax-Om body she'd requested that I come to the fortress with her and help her with something. Wanting to see this place I'd quickly agreed.

"This is called a birthing matrix," Kara Kent told me as we entered a small and hidden part of the fortress "Do you know what those are?"

While this hadn't been the case in the version of Krypton I remembered, I knew that in some versions of that ancient culture, children of that race were raised in a birthing matrix separate from their parents until a certain age is reached. I was sure that in one of the comics I'd read the scientist Jor-El, believing Krypton was doomed, redesigned the chamber for interstellar travel capabilities, and equipped it with a hyper-light drive. It was used to send the Last Son of Krypton, young Kal-El to the planet Earth before Krypton exploded. The craft landed in Smallville, where it was discovered by Jonathan and Martha Kent.

In the animated film Justice League: Gods and Monsters, General Zod stops Jor-El before he can implant his DNA in the Matrix, using his own instead. Due to that and other differences (including another foster family), that movie's version of Superman is much more ruthless than usual, although still largely benevolent. His mother's influence no doubt.

"Yes, but I've never seen one" I answered, knowing that Supergirl knew about my Kryptonian form and that I had the memories of one of her race "Did they use them here or was your Superman sent by a ship as a baby?".

I was sure the later was the case.

"This is a little of my world's history" Supergirl explained, "They went out of style centuries ago, but I found the design in my Uncle's databanks and I figured that one day I'd find someone out there in the universe, or another, who I was compatible with".

I got the feeling that I knew where this was going.

"My Kryptonian form will have DNA the matrix will accept," I said.

This Matrix was a complex bit of tech, but in terms of function, it was just an artificial womb it would combine two people's DNA in an optimal pattern and then grow the child inside it. No need for any parents until the kid was ready to start learning its place in society. Which here on Earth would be a superhero.

"You want to make a new Superman" I realised.

She smiled at me. Seemingly impressed that I'd figured it out.

"All I need from you is to place a finger on the reader" I was told "The matrix will take a DNA sample and that's it. The fortress will look after the baby until he's ready to come out, then it will be my turn, when he's older the League will teach him what he needs to know about protecting the world".

For humans siring children was normally a bit more involved than surrendering a few skin cells.

"This world will need Superman in the future," Supergirl said.

She was right about that, and while there was a chance I might help to make an evil Superman, the kid would still be Supergirl's son and a member of the House of El, who were normally good guys. I debated this internally and then after a few seconds of more thinking before changing form and placing my finger on the device. It took a sample of my Kryptonian DNA and that was it as far as I could tell. Kara must have supplied it with her DNA before now.

"The little guy will use the House of EL for his name rather than Om since he needs to wear the right symbol," Kara said as she pressed some buttons "So we'll go with Jax-El for the name".

With that, we were done and we both headed out of the room.

"You can come to check on the little guy in a few years if you like" Supergirl offered.

I didn't think I would as it would be unwise to get attached in any way. I was just a DNA provider. Leave it at that. And I would not be providing any more of my DNA to the females of this world. While it might seem sexy to be able to go around knocking any female superhero in this world that would consent, and that would be a lot of them, on a practical level that simply wouldn't be the smart thing to do. Providing tens of thousands of healthy human males was the only way to solve this world's crisis.

"And I was hoping for some sex too" she casually mentioned as the young alien babe took me to her room, "Barbara told me your worth a ride, and I might never get the chance do it ever again".

Kara then pushed me down onto the bed and took her top off. I'd seen bigger before but the gravity-defying perkiness of Kryptonian boobies was enough to turn even me into a drooling idiot, at least for a few seconds. Thankfully she didn't see the drool as she'd already shoved her tits into my face.

"Men like these in your universe, right?" she asked.

I answered by sucking on her nipples, something that made her giggle in delight and put her arms around me, I played with the perky goodness that were her funbags. I didn't get bored with that, but she decided that something more needed to happen.

Now she was working her way down to my trousers. However, rather than try to ride me once my belt was off Kara Kent started giving me a blowjob. She stopped pretty quickly as if she was worried that she'd done something wrong.

"You don't mind do you?" she wondered "I might never get a chance to do this again, and we did just make a baby together".

Somehow I was okay with this.

"No go right ahead," I said trying to sound cool.

As she continued sucking me off Kara's other hand vanished between her legs. She got herself so worked up she was already moaning which felt great given what her mouth was full of.

"Okay I can't wait any longer," she told me as soon as I'd started to relax "its time for the main event".

Quickly she removed her skirt and panties. Then she laid down next to me on the bed before she opened her legs. Pretty much an open invitation what with her bare wet cunt spread out before me. I then got on top of her and slowly thrusted into her, being rather nice and gentle to the Kryptonian as I was using a body that should be of equal strength and toughness, so I had to be careful.

"Harder and faster too," she demanded.

Okay so maybe not all that careful.

"I want you to do me hard," she said, this time making it sound like more of a request "Please, please, please".

That worked so I did as she asked. I began picking up both speed and pace. Her moans grew louder and louder as I forced myself deeper inside of her with every thrust. Her hot wet cunt was like a vice around my cock and her very flexible legs were already wrapped around me.

"YES! OH YES!" Supergirl called out as I ploughed her into the mattress.

She was so loud the room seemed to shake a little, and if I'd cared enough I might have asked what the bed was made from as it was taking one hell of a pounding. As was Supergirl. I was now ramming my hips into her and she loved it judging by how verbal she was getting.

Then it was time, I took one last thrust and pushed as deep as I could, releasing my seed into her womb. An act that made her scream delight despite it happening sooner than I would have liked. Stupid super tight alien pussy which wanted to eat my cum so badly.

"Can I keep these?" I asked while we got dressed.

By now I was holding her panties. They were very red.

"I don't have any spares here," she said, biting her lip "I'll be flying without any on".

That made her smile.

"Okay I'll just fly back to the farm real fast," she said.

I pocked her underwear and put on my jacket, which had the House of Om symbol on the back. Kara didn't react to my shapeshifting, but she had known the Martian Manhunter, and it wasn't as if she could afford to be fussy.

"So can do the whole magical door thing to get home?" she asked "or can I drop you off somewhere".

I opened up a portal and stepped back into my penthouse suite. I wanted to rest a bit before coming back to the world without men to see if I could bang more female heroes.
