It's a humanoid robot monster. If it were a Fakemon, it would be mono Steel. Vaguely inspired by some of the stronger Eggman robots from Sonic Heroes and One Piece's eighth main character, Franky.
This cyborg originated from Unova, but Alolan people updated its appearance to execute its own Z-Move:
Satellite Punch! How SUPER is that!?
(Looking at its design, it's obviously a stereotypical New Yorker's super robot.)
