Springtrap: he defintely could work since he had fun when he's killing, like he even did cruel experiments on them so he can work!

Gorefield: he can easily destroyed the whole universe and can transform into bigger form i know he's already in pc2 and terror whispers but he can perfectly fit in cc.

Corpse: basically just like apex but on sterdiods, he can easily work with his brute strengh and force.

Entity 01: he is basically the lord of fnaw and he's also really powerful who take on bowser form, but they had to make a copyright free design of him and then bam, he got added!

Aiden: i feel like she could work by brutally tortured them and hunting them, basically just like jeffrey woods but a russian and more aggersive, i mean serial killers seems scarier than powerful monsters. (like if cyn and uzi can get in i think aiden should)

Red: he definetely perfectly fitting in the game with his aggersive personality and even a force he had, of course he even killed godzilla in the game, so red fits perfectly!

Lucifer (pony island): lucifer seems fitting at all, plus pony island is obscure and underrated, so we need more obscure characters in chase game. (not overrated characters like miss circle, blue, alastor and others)

Room: i was a huge boisvert fan back in 2023, but i think room can easily fit in cc, he can give the survivors depression and paranoia, so room seems fitting at all!
