One of the first of a Character set Cuttlefish commissioned me to do.
In the beginning I brought it up to him "hey why not have animal themed features?" I'm not quite sure what inspired that train of thought but I always thought it'd be fun to make this brawler type character more details with an animal themed plating here and there, without him officially transforming INTO an animal.
It gives his tank mode more smoothed out angles, certainly.
Also battle scarring. Every good brawler needs good battle scars.
