Cortex and N. Gin Redesign

I wanted to give the feel that they've succumbed (including Nina) to the effects of continuous amounts of mojo, mutanting them.
They've also gotten mutant powers to an extent.

Cortex = Powerful brain blast to vaporize his enemies.
N. Gin = Can thrive in extreme cold and freeze mutants with his icy breath (Like the Ratcicle)
Nina = Somewhat able to breath fire and spit fire balls.
