I sketched out a Mako shark guy for shark week, after the fact, but hey, I recorded some of it so shark week is still going on for me. XD
Second: Hammerhead (Adult)

Okay, quick rundown:
He's still nameless as of yet.
He's part of a gang of sharks. He's very quiet, intelligent, and a bit unnerving.
Fighting is not something he does often, but he's not afraid to. He's actually a better fighter than most and he attacks with fluid, incapacitating martial arts.
He has a crush on the gang's leader!
He dresses oddly, and never seems to get hot even though he wears his fluffy coat most of the time, except the summer really.

Once I get all of the gang drawn I'll try to do a full-color group depiction.
EDIT: Not sure of that now. I will finish drawing the Boss at some point, but instead of working on these more I might just add them to comics later as cameos if nothing else. No reason for me to waste time on these guys having their own story.
