Angel Fanboy(天使愛好家 Tenshi aikō-ka) is an enemy that only appears in a special stage called Wrath of Heaven for a limited time. He isn't a problem, because he deals only 1 damage with long reload.
In the special stage Wrath of Heaven, Angel Fanboy appears as a weak enemy to remind you that anti-floating cats, such as Shaman Cat, will not deal anti-floating affects. He only does 1 damage with a long recharge on attacks, has 5 health, and is strangely a metal enemy.
