Little Mutant Mouse

A Long time ago mice and cats lived together in peace
Then one day the sky got covered by an toxic green clouds,
a couple days after, we the mice began to obtain strange abilities
but no cat developed any powerthat made them very resentful

the cats take over the city blaming us of being inferior mutants
but the mouse mayor defeated Bill, the cats leader.
exiling the cats out of the city for ever

but Bill had a plan B and thanks to magic he locked out the city
on a small crystal, he caged everyone except a reduced group of mice

the inventors of machines Isaac and Ross one of a few mice that was born with a tail
Nunki, black belt in the art of blue fire fist
Askella, a hateful mouse with telekinetic powers
and finally our hero Kaus Rayet, with the ability to become dark matter
being the only who can get inside of crystals.

now this small group have the duty of save the city
