Idk who to make the Golden Freddy soul :(

I need y'all's advice for who to make the Golden Freddy soul/TOYSNHK. In my au, it can't be CC, because CC is not a vengeful spirit. I'm not really a fan of "Cassidy"'s character, so I don't want to do her. Anyone else have any characters they use, and also a little lore about them? Ty‼️
