The final boss of Cats of the Cosmos Chapter 1. He attacks three times with lightning strikes, powerful enough to kill an Awakened Bahamut with two lightning strikes. He also has insane range, only being outranged by two cats (Hacker Cat and Assassinlan Pasalan), both of which do negligible amounts of damage. Note that it is near necessary to max out the Mystery Mask treasure in Ch.1 in order for him to be at a beatable difficulty level for the average player.
Because of his huge range, it is recommended to use cats with fast movement speed and high attack power such as Awakened Bahamut, Swimmer Cat, and Can Can Cat to rush in and get quick damage before the next wave of Starred Aliens arrive.
