The Alaska Bullworms
Colors: blue and pink
It's a great reference, and a unique mascot.
The Dallas Stallions
Colors: blue and gold
I just want a Dallas team tbh.
The Chicago Ice-Devils
Colors: Ice Blue and Dark Red
I'm a fan of most Devil based mascots and Chicago probably needs a team.
The Gothenburg Bats
Colors: purple and black
Sweden. Also "Gothenburg" is pretty close to Gotham. Also it sounds super goth.
The Mexico City Cucoys
Colors: green and black, maybe black and gold
Some very southern flair and a folk creature that parents tell their kids about to scare them.
