I was about to rip on Red Bison for not knowing a bison and a buffalo are two completely different animals and their Big Team Hissatsu, Tokkou Buffalo Train, doesn’t have anything to do with their team mascot creature, but...
...It actually looks like maybe they already know??
Baek’s Bison Horn move absolutely does accurately depict a bison, and Tokkou Buffalo Train does indeed take the shape of a buffalo. The horn shape and size, the head shape, and the general build of the two Big Red Aura Monsters are Distinctly Different and accurate to each COMPLETELY SEPARATE CREATURE.
They are not the same animal. Do the Red Bison guys maybe realize they do look different, but without actually realizing they aren’t just variations of the Same General Thing?? They aren’t closely related and they aren’t even found on the same continents, guys.
