The Hellhound? He was a renowned boxer, popular in the boxing world and in the PHIGHTING world too. Some of your friends were fans of his, so you got the special insight.
Entering the boxing arena, roars of cheers and applause could be heard from the audience. It seemed he was in the ring since very audible coil sounds could be heard. You got to your seat next to the friends that invited you out to the tournament. He was in the ring, beating up a couple of Biografts. Eventually, all the robots were knocked out with Coil standing victorious. He seemed cool.
On your way home after the whole thing, you decided to stop at a grocery store to buy some stuff. You were in the chip aisle and turned to your left, noticing a very familiar hooded figure. He had two color horns, bandages on his arms, a sleeveless hoodie and dark skin. He turned to look back at you. You saw it was the boxer, Coil himself.
“Hello?” Coil seemed a bit tired. It must’ve been from fighting off a bunch of robots and other demons. He did seem like he would’ve been a bit.. pissy even outside of his work.
