Just some ideas for a new superhero I have in mind called the Amphicyon who is a wolf-bear hybrid who decided that once he became a superhero (powers mostly like Benjamin Grimm of the Fantastic Four) to take the name of a prehistoric creature as his moniker as it too was a combination of wolf and bear. The shirt and pants are green with glove-gauntlets and boots of black as well as a black belt and full face mask and cowl of the same color.

This is part of chest logo with a pair of red bear claws beneath and is repeated as the belt buckle with the red bear claws on his thighs.
