Idk how rare this is but I didn't even know it existed until today when i got it, and looked at the wiki to find that its been able to occur since the FL upd but is rare. Judging by the fact almost half of my playtime right now comes from since the FL update (as well as the fact that I only saw one YT vid of this upon researching it) I would assume that its REALLY rare
In case you we're wondering, It functions exactly the same as evil scary but is: -(what I assume to be) twice as large -Has lower-pitched sounds -Bounces on larger intervals (much slower) -Has a hitbox that extends up to around his hands -Does the same damage as normal evil scary (I believe) -Bounces much further His special move where he flies around in the sky and dives on anyone is INCREDIBLY hard to dodge when anywhere around him. His ramp-up move where he screams is different, only doing around three bounces but travelling further on each one (because of his slower base bouncing speed and larger bounce distance)
