Gerbil's a little out of place compared to the other secret bosses isn't he
>Puppet man involved with two Dark Worlds who mirrors Kris's situation as a puppet and seems to have been in contact with FRIEND who itself is probably an overarching supervillain
>Some horrible creature hidden in fiction within fiction that knows what Kris is thinking and wants to see them enjoy violence, fight room is inside the Shelter and covered in Titan eyes
>A dead man brought to life who rejects the whole schizoboss schema AND the prophecy who in life knew the prophecy in and out and wrote his own adaptation of it
>Clown that went to jail for having too much fun
It definitely feels like there's gonna be something more to him later
