Gato

ガトー

Gato is a prominent member of the Dark Guild, Naked Mummy. He has a peculiar habit of repeating sentences twice, with the second utterance following the first after a few seconds, without realizing it, something about which he is always informed by Zato.
Gato is first shown in Naked Mummy's headquarters, brutalizing one of their comrades for not having brought back any money, having been defeated by Lucy Heartfilia while robbing the LOVE & LUCKY merchant guild.
