So Arrellmon will not evolve?

3118974 He's not going to become a three-story-tall Windigo, no. He's gonna stay the same size, but he'll still evolve in terms of his powers.

3118976 you could say the sprite stays the same but he still evolves?

3119448, a better explanation would be that he got a new move-set instead of evolving, like how Bulbasuar can get solar beam instead of becoming Ivysuar.

I thought it was a metal cestus from AC.... well, now just to wait and hope for a hidden blade or something.... or maybe a hood....
