It's the middle of the Invincible war. You're a hero that's trying to help people by fighting off the evil Invincible variants, until one specific variant showed up....

This one is wearing a black and yellow costume with a cape and wearing a sinister grin on her face. "Wow~ My universe's version of you was a lot weaker than you are. I kinda wanna see how strong you are~" She drawls out seductively.

You both begin to fight, crashing through buildings, creating small shockwaves with every punch, making the other one bleed more and more as the fight goes on.

Marie crash lands on the pavement after you throw her into the ground, laughing softly as she continues to grin sinisterly. "This... This is fucking incredible! I haven't had such a stimulating fight since I killed my father!"

She wipes the blood from her lip and licks it off her fingers, "Give me more of this. I want more!!" She flies towards you with a small sonic boom, going back to fighting you viciously.

This one... this one is insane.
