In Bellwood

Y/n was investigating recent alien activity on earth. one of the aliens attacked him had a brains and one eyes, this wouldn't be the first time he encounter an alien like that he was in the sky trying to disable a ship that was shooting a laser below, he was now Humongousuar hanging on the edge, as the laser was heading straight for a hospital. Gwen  couldn't help due to her being busy so he was on his own. and he thought he would never need the omnitrix again.

Humongousuar: No you don't!

but he ends up falling from it crashing through the ground making a huge crate the ship crashes into a nearby cliff. but humaongousuar falls into crater transforming back into Y/n who was dazes from the crash.

Y/n: Not fun.

He than gets up as his knee was still sore from the crashing into the ground, he than gets a image in his head causing him to hiss in pain.

Y/n: Wow! what a headache than again I did land on my head so I'm not surprised.. but why do I get the feeling someone needed help.

He noticed the omnitrix was out of juice so he was going to take care of it in the morning. as he got out Superman who was flying back to metropolis saw the whole thing went down he checked if y/n who was humongsuar was alright but was stunned to see him turning back he than remember hearing rumors about the omnitrix.

Superman: the omnitrix does exist.

later the next night.

Y/n got the same message after taking down that ship from last night so he deiced to now look into it.

Y/n: sorry, but if people are in trouble I can't ignore it.

He activated the omnitrix choosing the alien he wants to be he chose a flyer slams his palm on changing into one of his aliens.

Big chill: Big chill!

He smirks knowing this was the alien he wanted phases through the wall flies to the location where someone needed help.
