Removing easter egg characters is NOT allowed.
Anyway, here is my list:
I don't hate Foxy, but he is definitely my least favorite member of the OG band. Plus his jumpscare looks pretty bad.
Again, I have nothing against BB. I just think the other animatronics from FNaF 2 are more interesting.
Phantom BB is probably the most boring FNaF 3 antagonist tbh. Nothing much to say about him.
Jack O Bonnie is cool and all, but he is still my least favorite FNaF 4 animatronic.
Electrobab is extremely irrelevant, and has one of the most bland designs in the whole series. Easy pick. (Cry Breeze)
I find Happy Frog's voice quite annoying, plus I don't really care about her that much.
