With a nod to various minor league teams and my general silliness, here are my suggestions:
Tornadoes, Strombolis, River Chickens, Blitz, Sheepherders, Mutated Carp, Grouches, Brain Eaters, Indigenous People, Psychopaths, Pterodactyls, Cutters, Rottweilers, Homesteaders, Tanks, Sewer Monsters, Elephants, Donkeys.
