The Devil's Advocate: Extraterrestrial Alliance

Summary: Answering Optimus' call, a group of Autobots head for Earth, but are separated from the main group as they landed on the wrong continent. Europe. Lost and in need of assistance, they make a deal with the devils and demon hunters of Devil May Cry…

Disclaimer: I do NOT own anything of the awesome Transformers or Devil May Cry games… if I did, I wouldn't be writing this in the first place… Other things mentioned in this fic that may have licenses or other things belong to their owners. I only own OCs and the story plot…

Rated T for language and violence.

Updated for grammar and spelling check up: 24 Aug 2009

Just a few things before you read:

1) This takes place after the Transformers Movie '07, but before 'Revenge of the Fallen'.

2) For Devil May Cry it is post DMC4… other changes are interlinked with the plot…

3) Slight AU for both Transformers and DMC… not entirely canon.

4) While in the media and the movie Revenge of the Fallen states that all three motorcycles are one as Acree, here I will separate them into three according to the toyline as Acree, Chromia, and Flareup.

A/Notes:

First crossover fic folks! And as well as my first ever fic here (I'm new, excuse me for being noob). Be gentle and bear with me and be gentle with my grammar, English isn't my first language. This fic was inspired by the fact that both Transformers have twins in them (which I love!). This is a Vergil, Dante and Sunstreaker, Sideswipe friendship fic. Also a dedication for the first Devils and Transformers friendship fic (there will be others in this fic) on fanfiction dot net. Constructive reviews and ideas highly appreciated! On with the story!

Prologue: 'Devil Twins and Robot Twins'


Switzerland, Bern

Outskirts of Bern

An Old Large Mansion

08:00 Hours Local Time



Cleaning was never really Dante's field of expertise.

He groaned as he looked on what seemed to be an awfully long list of things he had to do for the day. 'This is torture', Dante rolled his eyes. As if being the one of the top people responsible now for their status as Devil May Cry had finally been elected as a worldwide devils and demons organization (in secret), things had been rather 'hectic' as his twin would have said it… Their father's mansion had now been turned into the main headquarters of their hunting activities and 'pest' control on the supernatural.

Not that Dante had wanted it on the first place, he had preferred staying in New York and was happy the way it was. The cramped, rusty, old building was more settling for him.

Dante Sparda, known by most hunters through his alias as 'Tony Redgrave', he was considered to be one of the best demon hunters in the world. His messy silver hair looked very much like a mop. Clad in mostly red garments from his red leather overcoat matching pants with a black undercoat, he did stick out of the crowd. He was mainly considered to be a friendly, slacker, humorous, untidy, trigger happy for the love of guns, and perverted (at times around ladies) demon hunter. Dante looked much like a person in their mid twenties yet, he was actually at least 30. He started to realize that his other blood had started to really kick in as he got older.

The blood of a Devil.

Not any devil for the matter of fact, but the legendary Dark Knight Sparda. As in the world of today, many stories of his father's deeds were considered as fairy tales, myths or just legends. He was one of the most powerful devils to have ever been spawned in Hell. Yet what made him different from any of the other Devils, Sparda, with a few of his followers had turned on their own kind for the sake of humanity those somewhat 2000 years ago. Many centuries after, Sparda was wed to a lady Eva, and with her he had two sets of twins Vergil and Dante with Nero and Lily.

Dante looked in the mirror as he knew he had started to stop aging. Devils were considered immortal (unless slain in battle); though he never really dwell on the subject… the idea on never aging when you were around humans was frightening. Although he was a hybrid, his devil blood seemed to make more of its characteristics than his human blood. He was glad that his human form was intact and he did not have to deliberately conjure it to keep up his appearance like normal devils.

"Complaining in the morning already, Dante?" Vergil said with a hint of amusement in his voice, appearing out of nowhere as he usually did to deliberately frighten his twin. "Quite a list we got there."

Dante yelped and turned to his twin in huff, "As if work back in New York wasn't enough!" He simply detested when Vergil teleported with his Dark Slayer ability to creep up behind him.

"Well, you were practically dozing off most of the time," Vergil corrected, regretted to have asked to hear his brother whining as to the start of the day. "Grow up; my list is thrice as yours. We have to finish it off by lunch."

Dante gaped. "LUNCH? But that's four hours!"

'I can't believe he's my twin', Vergil snorted. The elder twin gave a smack on the head to the younger. "Don't whine like a child, brother. It's best to get it out of the way, than leave it to be in your way later."

The red clad twin only stared at his by-five-minutes older brother in annoyance. Sure, they were a mirror image of each other. But unlike Dante, Vergil was the polar opposite, calm, ambitious, extremely knowledgeable, neat, heavily organized and somehow carried an air of a noble. Instead of red, he was clad in a blue azure overcoat with black leggings and his silver hair swept back over his head. If there was an instance that there was a play in the theaters of the story of a royal and a poor beggar, it was obvious who would be the 'Prince' and the 'Pauper'.

Vergil's return had been a surprise for Dante. After surviving been controlled by the Dark Prince Mundus and even thrown into the Void realm, his brother was different than what Dante had known him for. It was ironic then, they had to fight against each other for their father's power. His thirst for power had somehow gotten him to the point where Dante was forced to defeat his elder brother. And in the battle at Mallet Island, Dante without knowing Vergil was being controlled as Nelo Angelo, killed him.

Or so he thought.

Dante raised an eyebrow to the end of his list, "What's with the 'P.S. find metal scraps when the sun is down?"

"Our current residents who live in our basement would be the one requesting for those," Vergil stated as he looked at his own list to find the same thing. "At least that takes one job off our list for this afternoon."

"We have to go back to the car junkyard?" Dante replied skeptically.

"Yes," Vergil said dryly as it was the most apparent thing in the world. "In addition, we should get some spare metal to melt down and use it for our base resources."

Like usual, Vergil was being his 'resourceful self'. Dante couldn't deny at all how much Vergil reminded him of their father, he could be deathly cold to other people at one time and caring when he wanted to. But the red clad half devil knew Vergil had an attitude problem when it came to meeting new people or people he didn't consider commendable to be near him, in which, he would simply ignore them as if they weren't there and listed them not worthy of his time. Still, Dante considered Vergil as a pain in the 'arse' as his elder twin would keep that 'high up' air around him most of the time.

Dante sighed, "I thought last time was our last stop to that place. We still have to-"

"I thought so as well, but you might not have to worry much," Vergil interjected, "Nero and Lily are on their way from Fortuna to help us this time with Lady, Trish and Linarien. I heard there's a crew that will be helping out in the basement as well."

Dante laughed at his brother, "Hah! No wonder you're not that stiff going to that place toady, bro! You've been aching to get together with Linarien!"

"Shut up, Dante." Vergil said in a dangerous tone, yet it was ineffective as his calm and collected demeanor was slightly off with a rouge blush on his cheeks.

"Yeah, say all you want Verge," Dante smirked as he found great blackmail material. "Where's the Love? When's the wedding? Wait, how about the baby in the carriage?"

Vergil's eyes narrowed as it hit a nerve and quickly as it came…

'SPLAT!'

Dante had found Yamato stabbed in his stomach through him.

Dante looked in surprise as he found his brother's katana in him. 'Ok, I think… I crossed the line.' No sooner later, Vergil took his sword out, flicked the blood of, sheathed it, and headed in the other direction. Dante coughed a bit of blood out as he balanced himself with the help of the wall beside him. For any normal human, they would of died from such an act and be blood stained on the floor. For one who was a half-devil with fast to near instantaneous regeneration, it was an equivalent to a punch in the gut.

'Next time, I should only blackmail Vergil if he doesn't have Yamato with him,' Dante made a mental note; soon to realize that it was impossible as Vergil always carried it around with him.

A somewhat evil chuckle came from his twin, who for the most part knew what Dante was thinking about. Don't ask how, it's a twin thing.

'First I got a ton of things to do, AND THEN I get stabbed so I have to clean myself before I get to do anything… talk about bad luck.' Dante thought sourly. 'Dammnit.'

While the red clad half devil was deep in cussing, Vergil Sparda quickly walked out of his brother's view eager to settle every task that was on his list before lunch if needed. The only reason why his twin complied to do cleaning because their father requested it, as strange as it felt having their father now living was amongst them. He then focused his thoughts on Linarien.

It was true he had missed his fiance, but he wanted for her to learn more what healing magic the sorcerers in Fortuna had to offer. He was not above about females having a part in battle, but if the opportunity arose that she was hurt, it would make him feel better that Linarien could take care of herself. She had said over the phone she developed her ability to repair technology with her powers with more accuracy, and was very eager to share the knowledge with him. Even though Vergil was not as skillful as she was in the fixing/healing department in magic, to him any knowledge was priceless and come in handy in unpredictable situations.

Unlike the Trish who was a demon and Kyrie who was a human, Linarien was in fact an elf. And generally because of her race, her powers were more intertwined with nature. Both he and Linarien were a few who truly loved to dwell in knowledge and especially books. He was looking forward to have her by his side and learn more from his fiance this afternoon.

And certainly, he did not need his twin's noisy commentary to ruin his day.


Somewhere in the Universe

Milky Way Galaxy

In great speed towards Earth's solar system

08:01:34:2323 Hours, Minutes, Seconds, Astro-seconds



In a few Earth hours, they would be finally reunited with their Commander and their comrades.

The whole crew of Autobots had met each other on the way towards Earth as they heard their call, a large number indeed as a total of 11 Autobots or 11 bursting comets in what had seemed to be in a formation.

Up front were Jolt and Prowl.

Jolt was a mech with a twisted fighting sense as he had a peculiar habit of running around his enemies and making unexpected strikes. Considered to be at a mid age (according to Cybertronian age) he was a very flexible bot that was easy going to both the youngsters and the elder bots.

Beside him was Prowl, who was infamous as Optimus' 2nd in-command and was the Autobots' military strategist. His best weapon was basically logic, but at times when things did not compute to his logic his circuits in his head would fry. He certainly wasn't quite the bot to handle things that were unpredictable or solely things that came by chance.

To the very left and right of the two bots who were at front flowed Skidz and Mudflap. They were considered as the 'minor twins' as though they could cause trouble, they were nothing compared to the larger twins. The only difference that could set them apart was the fact that both of them used very 'colorful' language, swearing was an every day thing…

In the middle of their formation there were four femmes Flareup, Chromia, Acree and Silverstar.

The four of them were a tight group, as they were the only female Autobots far from home. Chromia and Acree were the older femmes who had in many ways experienced the wars as it was natural that Flareup and Silverstar always looked up to them in support. Despite of their smaller size in comparison to their male counterparts, they weren't to be underestimated as they were a scary lot when they had their guns and blasters out.

And in the rear Sunstreaker, Sideswipe, and Blitzout.

Being the major of the twins, Sunstreaker and Sideswipes were very much the agents of pranks and trouble. But in the turn of the battle, both were considered to be the most ruthless of fighters in the Autobot faction. They were made to be assault warriors since their creation, and even many other Autobots had questioned them before why hadn't joined up with the Decepticons instead.

Blitzout, another young Autobot near to the major twins' age was quiet a bot when one did not know who he was. He was quite a chatterbox and loved pranks as much as the twins, being close to them he was considered as their younger brother.

/ We'll be arriving on earth in a few joors (a couple of earth hours). / Prowl announced. / Remember, we're heading towards the coordinates that Optimus sent us. Should there be a Decepticon attack, try not to separate! If separated, ASAP travel to the coordinates! /

While Optimus Prime was gone, Prowl had taken most of the leader job. In most of the other Autobots point of view it was acceptable, others like the major and minor twins had to admit they did not like his boring, static, and everything based on logic attitude but tolerated it nonetheless. While he kept on droning on and on about the precautions about how to keep in formation as they headed for Earth, the other Autobots were listening to him half-heartedly. The reason being, they were all have conversations of their own through private com links.

Jolt somehow was in conversation with the minor twins, excitedly talking about how Earth might be a better place to offline more 'Cons'. Yet the twins were actually putting up the fact that the human race had so many languages, so to them they simply couldn't imagine just how many swearing words they could learn once they got there.

The femmes of course were gossiping. Chromia was thrilled to know that Ironhide was on Earth, but she was rather nervous to meet her spark-mate as it had been a long time since they had met. For that she had been talking to the other femmes in seeking out their opinion on the matter just to lessen her anxiety and felt re-assured. Of course Acree, Flare-up and Silverstar were ever more willing to help her out with her feelings than listen to Prowl. As Acree would have said it, 'Prowl knows nothing to where/when a femme is concerned.'

Meanwhile Sunstreaker, Sideswipe and Blitzout were at the back of the whole group in their own conversation. But they kept an audio receptor to Prowl just incase there were orders to act on.

~( What do you think those 'squishy' are like? )~ the elder twin bot wondered. ~( I can't really imagine fighting side by side with them. You think they can damage a 'Con? )~

~( I don't know, )~ Sideswipe said unsure. ~( But one of them did take Megatron down with the AllSpark… that does have to mean something. )~

~( Well, he is offlined. It doesn't make it any easier that Starscream or maybe his other in-commands are around still leading the Decepticons and hiding to strike. )~ Blitzout spoke up.

The Twins were rather disappointed when they had received Optimus' call to find out they had missed in on the action. Unlike most of the Autobots who preferred to avoid any fighting unless it was necessary or an order, Sunstreaker and Sideswipe were thrilled to take on any hunting job. Their specialty was destruction, as even Seekers would be wary of them if they were in the same vicinity. The only Decepticon they had faced together and was hard to defeat was Megatron himself, the reason why they had high respects for their Autobot Commander Optimus Prime.

The group had made a couple of stops on a few planets as they headed for Earth. Being disappointed and needed to get their frustration out, the major twins apparently took it on Prowl with their pranks. Poor Prowl, one moment he was in recharge in a solitude place… when he woke up he was half buried in sand and mud in his alt form.

The other Autobots took it as entertainment, as long as they weren't the ones being pranked.

~( Ah, well. If we didn't have a chance to offline Megatron, then Screamer should do the trick. )~ Sunstreaker said looking at the brighter side. ~( I'm sooo going to kick his 'aft when I get my hands on him! )~

~( You go big bro! )~ Sideswipe cheered. He was also looking forward to kick for 'Cons out of Earth. But he couldn't help but feel a bit worried.

Blitzout only gave a nudge to the elder twin bot to give a hint there had been something wrong.

~( Sides? You OK? You're not usually this quiet… )~ Sunstreaker asked thoughtfully.

Sideswipe shrugged and said what was on his mind. ~( I don't know, I just been having a bad feeling lately. But don't you think it's kind of odd the Decepticons are still around when the AllSpark is gone? It makes no sense, Sunny. )~

~( Beats me, 'Cons don't stick around for nothing to conquer. It's not like them to do that.)~ Sunstreaker noted. ~( I feel the same way as you do. But we'll find out once we meet Boss bot. I think Earth is like what he says, 'more than meets the eye'.)~

Eventually, Sideswipe turned to his younger companion, ~( What do you think Blitzout?)~

~( I have to agree to with Sunny about what Optimus told us.)~ the younger said and hesitantly said ~( You think we should watch out for Decepticons? As far as I know they are on edge, you think they would- )~

~( Attack? )~ Sunny finished for him. ~( Most definitely. If Optimus has made a pact with the squishes, and all… the 'Cons are at a disadvantage because they're not welcomed on the planet. )~

~( Good for us, but it doesn't mean we're safe. )~ Sideswipe said. And then he added, ~( They're going to try and kill us before we even reach the atmosphere…)~

~( WHAT?! )~ Blitzout shouted.

Sunstreaker warned, ~( Decepticons won't be merciful, not when the whole planet is not welcoming them. It makes more sense they will try to take us out before we meet Prime.)~

~( No wonder Prowl's worried, and droning on and on. )~ Sideswipe nodded. ~( And by the looks of it, Prowl's going to do a rush strategy. )~

Blitzout panicked ~( What should we do? )~

~( Keep an optic out for any Decepticons )~ Sunstreaker stated.

~( Other than that? )~ Blitzout hoped for another encouragement.

~( Keep your wits under control )~ Sideswipe chuckled in amusement.

~( You bots aren't really helping )~ Blitzout grumbled as he realized in embarrassment they were playing with him.

The twins laughed.

~( Easy, lil' bro. As long as we take the rear and Prowl with Jolt takes the front, we'll do what we can to protect the group)~ Sideswipe backed-up. ~( No point panicking, but it's true we're at a disadvantage cuz we're in our protoforms. )~

~( I wonder how Bee is doing. )~ Sunstreaker said. ~( It'd be fun with him to join us in our pranks once we get to Earth. )~

~( I know. )~ Sideswipe agreed. ~( You think he'll be a goodie bot? As far as I know he's been around 'Hatchet' and Ironhide for a while. )~

Ah, yes their favorite prank target no. 2, Ratchet. They certainly had some sort of a vengeance when it came to being prodded by the Autobot medic after sustaining major injuries which the medic labeled them as lunatics and in return they gave him the nickname 'Hatchet'.

~( Nah. He's too mischievous and young for a mini-bot to keep following their old ways. )~ Sunstreaker pointed out.

~( Point taken. )~ replied his twin.

/ Alright, all of you. Turn on to turbo; we're going to speed up our move. Autobots! Advance! /

With Prowl's command, the whole group turned on the turbo boost to fasten their arrival on Earth.

TO BE CONTINUED...


I own my OCs, Lily, Linarien, Blitzout, and Silverstar.

I thought it would be interesting to make this fic with Sparda alive.

I'm still figuring out their Alt forms coz I was kinda disappointed that Sideswipe was not a Lamborghini in the movie… grr…

Pop in a review! Again, any comments, suggestions, and constructive ideas will be highly appreciated!

I could use a beta reader… anyone would like to volunteer?
