A Certain Scientific Omnitrix: Book 5, Total War.

GekoBen.

"BOOOOMMMMMMMMM!!! BOOOOOOMMMMMMMM!!!!" Mikoto raged through multiple buildings, sending out electro sonic blasts out everywhere.

Mechs and Academy City Soldiers were sent flying as Mikoto flew into the air, and blasted the street apart.

"HEEEELLLL YEEEEAHHHHHH!!!" Mikoto whooped. "This.. is AWESOME!!!"

Ben and Rex just stood there with Itsuwa, staring dumbfound, not even bothering to help.. not that they needed to.

"So.." said Rex. "She going to calm down eventually?"

"Yeah she will.." said Ben. "Don't worry, it's happened before. She get's riled up in a fight and she lets out all the built up frustration from her week into the enemy. This week she took the entrance exam for her high school.. so yeah.. HIGH stress."

"THIS ARMY IS MY B*TCH!!" Mikoto screamed. She created two discs made of lightning that instantly surrounded themselves in blue soundwaves. she threw the electro sonic discs out, and they shot around as if they were sentient, slicing off all the limbs of the mech suits, forcing them down.

"The cussing's new." said Ben. "Must've been a REALLY bad week."

Rex began to sweat. "Ehhhhh.. she's hot.. but.. she's scary."

"That's what makes her awesome." said Ben.

"You have a weird taste in women." said Rex.

"That's the best kind of taste." said Ben. "Anyways.. Rex.. this really isn't your fight here.. you just got thrown into it.. we're going to be fighting some pretty tough enemies from here on out, so you should probably get out of here.. I promise when this is over we'll figure something out.."

Rex laughed. "You kidding? You're not the only one who can play hero.. you seem like decent people, so I'll stick around for now.. lend ya a hand."

"My girl probably still won't trust you.." said Ben.

"She'll warm up to me." said Rex. "Now.. any tips for getting on her good side?"

"Don't be a pervert."

"Oh.." Rex muttered. "Helpful."

There was a silence, as Mikoto dragged herself from a pile of smoking machines and knocked out soldiers. She stood next to Ben, exhausted, panting and breathing heavily for a bit.

Ben ran a hand through Mikoto's hair and adjusted it so it was somewhat neat again. "Feel better?"

"Yes.." Mikoto panted. "Now.. how do I get back to my normal clothes?"

Mikoto tugged at the mech suit. "It's like it's fused to my body.. I mean not that it's physically uncomfortable.. but the way it hugs my crotch so much is a little.. weird.. Oh crap I can't believe I said that out loud.."

Mikoto fiddled with the Omnitrix symbol on her neck collar, and immediately there was a bright flash of light, and the Echo Echo mecha suit disappeared... and.. it was probably a bad idea.

"JODER MIS OJOS!!!!" Rex screamed in spanish, covering his eyes and going red.

"WHHHHHHHAAAAAAA!!!?" Mikoto screamed, grabbing a piece of a nearby wrecked mech and covering herself with it. "DEAR GOD THIS POWER HAS PROS TO IT BUT IT JUST HAS THE WORST CON!!!!"

"You... er.. " Ben muttered, looking away, his face steaming red. "Did say that it shredded your clothes when it  transformed you."
