This enemy is the Alien counterpart of Gory Groom, except with more health, less damage, and less knockbacks. He also gains the ability to warp your cats. With his fast attack rate, he can destroy your defenses easily.
Cat Units with the Freeze ability (Surfer Cat, Balaluga, Akira, etc.) can do wonders as they can stop him from destroying your front lines and warping them back. Anti-Warp Cats can not be warped and Gorilliam will not be able to push through your lines, or at least slow him down. When Gorilliam is given higher buffs in later stages, Anti-Warp Cats start to become useless, as his damage is enough to kill or knock back most meatshields in 1 hit, in which case it is best to just use Psychocat or Surfer Cat to stop him from moving forward. Aside from Psychocat, Another good slower is Mitama the Oracle if you have her.
