Mutant Year Zero
A miserable little mutant, as ugly outside as it is inside.
Perhaps effected by the rot more than any other mutant, Gruber is a mess of flesh. He is one of the most mutated mutants in the Ark boasting a number of strange powers. He is believed to be involved in a number of criminal enterprises, but this has never been proven.
He is most often connected to the Boss Creed as, perhaps, his favourite slave.
