Angel Fanboy serves as a weak enemy to remind you that anti-Floating cats, such as Shaman Cat, will not deal anti-Floating affects to Angel enemies. He only does 1 damage with a long delay on attacks, has 5 health, and is classified as a Metal enemy.
*In each stage, there is strength magnification, the value of health and attack power varies due to this value.
*Time between attacks is the time of the attack from the motion end until the next attack motion start
Trivia
Despite being a Metal enemy, it does not say "(Metal)" after his name.
His English description used to be: "Blew his life savings on Angel goods. Discovered Angels can't be hurt by non-Angelic attacks after obsessively collecting Rare Cat Capsules." It was likely changed due to the fact that this was misleading.
He is the only traited non-event/collab enemy in the game whose name does not include parenthesis displaying their trait. Furthermore, he is the only metal enemy who lacks an obvious metal motif.
The reason behind his bizarre attributes is to prevent him from being killed in one hit before the player has the chance to read his sign, while not encouraging the player to bring an anti-Metal unit for such a trivial enemy.
His advice is actually incorrect in the case of one enemy: Variety Bears defy the rule by having both Floating and Angel traits.
