Gato's a key player in the Dark Guild Naked Mummy, best known for being absolutely brutal when guild members mess up—which he demonstrates early on by beating down a comrade who came back empty-handed after getting taken down by Lucy Heartfilia during a robbery at the LOVE & LUCKY merchant guild.
He's got this weird verbal tic where he repeats himself without realizing it, saying the same thing twice with a pause in between. Zato's constantly having to point it out to him, which Gato apparently needs reminding about every time.
