A faster and stronger variant of Gory. His DPS is very high and has Area Attack, so he can push through meatshields very easily, but has a bunch of knockbacks, similarly to Gory Black, in order to compensate. Overall, Angelic Gory isn't too hard to deal with by himself, but he becomes deadly in groups, especially when buffed.
Using mid ranged cats such as Paris and Dragon will knock him back fairly easily, allowing for a quick breather for your team.
Another good strategy for this enemy is to stall it with high health cats like Tank Cat/Crazed Tank Cat and hit it with ranged attackers. Rocker Cat excels against Angelic Gory, especially in his True Form, as he does considerable damage and only takes 1/4 of the damage. Dioramos also gets a chance to be useful against this enemy, but be wary that he doesn't get swarmed too quickly!
Juliet Cat might not be the best choice against this enemy as her long foreswing causes her to miss often with Angelic Gory's high knockback count. If you were lucky enough to receive any Ultra Souls or Delivery Cat, they also have a chance to prove their worth; as when stalled by stacks of Sanzo Cat, they will effectively stall and destroy Angelic Gory as well as any support he may have.
