Ben was a bit surprised by this Celestial Sapien hybrid attacking Equestria, and was also somewhat disappointed that he didn't have a fair chance to fight. Nevertheless, he wondered where Gwen and Kevin went. He hadn't seen them all day. Good thing his omnitrix doubled as a comms system. He dialed in his cousin first, just to see where she is

"Gwen, where are you? Last I saw you, I told you I was going for drinks with the boys, and a whole day passed. Are you okay?" He asked, waiting to see if she would reply. A minute or two went by with no response, until a static reply came by.

"Ben? I was looking for you all day! I am at this castle in Canterlot where I just found a poor little girl who was the victim of Albedo's hybrid experiment with the Celestial Sapien DNA. I am trying to see if I can undo the experiment with manna. Right now, it looks promising. Get your butt over here. Grandpa Max is here, too, discussing plumber stuff with Celestia. She is a bit surprised about previous human contact with aliens, given the whole Capitol thing back in 06, and how Max has been doing Plumber stuff for 55 years."

Ben wasn't really listening. He was just glad to hear that his sister was alive and well. "Okay, where is this Canterlot place? I am near this library where that hybrid showed up. Any idea how to get there?" He asked, just in case his cousin had any clue where to go.

"Yeah, just look west of where you are, and you should see a tower, just go in that direction."

Ben nodded "Thanks, I'll be right there!"

Ben needed to select an alien to get there quickly. "XLR8, maybe?" Ben said as he looked for the Kineceleran icon on his Omnitrix. He selected it, and the transformation worked!

"Yes, it worked this time, let's pedal to the metal!" Ben said as he ran over towards Canterlot.

The ponies that saw this blue blur running past them were quite surprised. They had seen Earthlings before, since the new deal was signed, but this? This was quite novel indeed.

It took no more than 20 minutes for Ben to get to Canterlot, but his transformation timed out once he arrived. "Goddammit, Azimuth promised to give me master control when I turned 18. I have been 18 for 6 months now. Maybe he forgot?" Ben thought to himself as the guards let him through. When he entered the castle, he saw Celestia and Gwen both using magic to try and resuscitate the 10 year old girl.

"Wait, you're telling me this little girl was the Celestial Sapien hybrid? I knew Albedo was crazy, but this is too much!" Ben exclaimed.

Celestia frowned: "It is true, Tennyson. This Galvan fellow is quite the problem. I am having trouble resuscitating her. Even your sister, who is a gifted mage herself, is struggling. She might die. It is truly horrific."

Ben thought for a moment. "Aren't there other unicorns who know magic? Like that purple one Nathan credits for saving his life?" Ben asks.

Celestia shrugged: "I don't know where Twilight Sparkle is. For all I know, she could be on another time cop mission with Nathan, or reading." She replied.

"Actually, I am right here, guys!" Twilight said, landing at the window. She rushed over to Canterlot as fast as she could when Fluttershy told her that the hybrid was a little girl.

"Ah, it is pleasant to see you here, pupil. Can you do anything to help bring this poor earthling girl back from her vegatative state?" Celestia asked.

Twilight was not entirely sure if she could do anything, since both Gwen and Celestia had trouble doing it, and Celestia was definitely more powerful than her. "I can try, I think?" She said, as she began to use healing magic. It doesn't seem to be doing anything.

For 15 minutes, Twilight, Celestia, and Gwen all try to use magic to heal the child, but nothing works. Gwen decides that enough is enough "I don't think we can bring her back." She says as she walks over to the child and closes her eyes solemnly.

"Oh shit, the kid actually died," Ben says, feeling horrible about it. Even if he wanted to use Alien X or Clockwork to rewind time, death is an absolute point in time that cannot be overwritten.

"I need to find out who this girl is, and where her parents are." Celestia says, as she opens a portal to Earth to contact government officials, and uses her telekinesis to carry the body to earth for burial.

"Well this is really bad. What do you think Nathan is going to do about this? If he finds out about this poor girl's death, I can only imagine how he would react…" Gwen says.

"One thing's for sure. When he gets back from his time travel thing, he will flip his shit." Twilight says solemnly.

"In the meantime, do you have any information on Albedo that I can use? Maybe the Elements of Harmony could do something useful this time, instead of the time gods stealing the show?" Twilight said sarcastically. While she is extremely grateful that Kronos saved Equestria (and Earth) from Luna and Tirek, she was annoyed that her friends couldn't do more to help out. Maybe this time, the tables will turn in their favor?

"Well, I do know that this isn't the first time I have faced him. He screwed up a few years ago, and got his DNA mingled with mine, so he looks like me, but with a red jacket and white hair. I think Azimuth said it had something to do with my DNA being the "template" for the Omnitrix, but I don't know for sure." Ben said, as Twilight was taking notes on this new foe. "Well, Gwen and Dashie went back in time with Kronos, so they must've seen him. I'll go get her, one minute." Twilight said as she flew out the window, eager to find Rainbow Dash to ask her further questions.

"Well, what the hell am I going to do here while I wait for Twilight to get back from wherever she is going?"

The portal that Celestia opened a few minutes ago reopens, and Celestia returns to her castle.

"Well, my sister did something stupid again, and it relates to you. She made Nathan go back in time to prevent the Omnitrix from ever existing in the first place!" Celestia said with urgency.

What, did Ben hear Celestia correctly? Rewriting history to prevent the Omnitrix from ever existing?

"Well, if that happens, then Albedo would never create Hybrid children, but on the other hand, it could leave a huge power vacuum in the universe, perfect for someone to take over more planets."

Celestia gasped: "Fuck! She is not reformed after all. She wants Nathan to rewrite history in order to make it easier for her to conquer Earth. She has been pretending this whole time!"

Ben feels something weird on his wrist. The Omnitrix begins to fade slightly out of existence.

"Oh no! Nathan already found Azimuth in the past! Can I even use any of my aliens anymore?" Ben wondered as he tried to select the Chronosapien DNA sample on his watch. If any alien can undo what Luna wants to do, it would be Clockwork. Sadly, it was too transparent to activate, but enough to feel it's presence.

Even though Luna was no longer trapped on the moon, she still occasionally frequented the lunar surface to collect her thoughts. She got onto a telepathic conference call with Tirek and Vilgax.

"Excellent news, friends. I sent that idiot boy back to the past to prevent the Omnitrix from ever existing. If he succeeds, not only will the universe forget what the Omnitrix is, but a power vacuum will be created, allowing for the three of us to split the universe equally!" Luna said, laughing with glee.

"As always, my dear Luna, you outdid yourself. I just hope that that boy rewriting time will undo my imprisonment in Tartarus." Tirek commented.

"Maybe if this works, I will never have to deal with Tennyson again, and even forget about him completely." Vilgax pondered.

Even though this rewriting of time would undo Azimuth's magnum opus, the three villains would remember their pact, due to a spell Tirek placed on the three of them. Luna would conquer Earth, co-rule Equestria with Tirek, and Vilgax would get the rest of the universe.

"What truly pains me is that alicorns cannot die, and this means I cannot kill Celestia. Frankly, my previous incarnation killed by Nathan died due to the universe ending. We must figure out a way to contain him if he finds out our plan." Luna tells her colleagues.

"Well, if I break out of this prison, I will kill him myself!" Tirek says, eager to exact revenge.

"You will not kill the boy. I have grown to like him. His life shall be spared, but a newer, stronger spell will need to be conjured to keep him at our side. Even that mare who Celestia fawns over admitted friendship is not the most powerful magic in the universe, which means I can actually defeat them. Ah, Nathan, you finally taught me something. The only constant is time."

"Indeed" Vilgax and Tirek said in unison.
