This protogen's name is Cobalt, and he was part of a development called project Noir, where he and another subject called Lu3ifer were experimented on with the dna of various mythical creatures. He received the dna of a hydra, which is why he generates venom and has extraordinary regeneration properties. The spikes on his back were a accident, but turned out to become a useful defense weapon. This protogen is uncommon, abilities vary.
