Man he has some very pronounced muscles leading to the individual toes on his feet. He looks he could carve out some serious damage using only his feet and toes alone, especially with the sharp claws on his toes. I know he is a boxer though. I like his broad shoulders and medial deltoids, he can obviously put forward some massive damage with each punch, throwing the weight of his beefy physique behind each strike. I like his color scheme, beautiful grey and white on his fur and the blue and purple clothing, suits him very well.

Everything you said is true. Shiro is more powerful than his younger twin brother, and his muscles are put to the test every time he trains or fights. Everyone in their family respects sports and no one would say they are not masters of their craft.
