Slash/Spike is a Mutant of a Turtle/Human that was owned before as Raphael's pet Spike.
Raphael got tired of his brothers and wanted to show him he could do well on his own so he took some mutagen and kept it 'well'. It mutated Spike into a bulky turtle that helped Raph until he turned and tried to kill his brothers.
Slash is a big fig and the enemy of the level Spiking things up. He has the same powers as all the other big-figs.(Ground Smash, Green handles etc.) and can grapple with his mace and throw ninja stars at targets.
