Character by me

Buck is a 28-year-old 5'6" rat who works as a personal trainer at a local gym. He prides himself on building up his arms as well as the arms of other gymgoers. Over the years, his gym has seen more and more sumo wrestlers coming in to get their pump on. Buck is more than happy to assist these big guys in packing on more muscle and he's not even all that concerned with their "extra bulk." He teaches them some weightlifting techniques and they teach him a bit about the art of sumo wrestling. In terms of personality, Buck can come across as your typical arrogant workout-obsessed gym bro, at least on the surface. Although, once you get to know him, he's actually pretty affable, quite friendly, and very understanding. This has become especially apparent after the time Buck has spent with the sumos. One can only imagine what the future holds for this iron-pumping rodent.
