The last bunch before prioritizing characters who show up first in more detail. Males typically are shaggier, have bigger tusks and body builds. Gato is the end result of stripping hair too much, dyeing it weird colors, and lots of hairspray and gel. He also uses neon green contacts a lot.
I have a feeling people will like these guys the most just because they have hair.
