Tobias Pines
From Transcendence AU Wiki
Toby is one of Bills reincarnations , to be exact the one after Ian .
Dipper found him starving and suffering on the streets , he actually wanted to get his popcorn and enjoy the show as karma punishes Bill's soul , but turns out Toby is basically a saint and dipper isn't cruel enough to leave an innocent suffering child on the streets . From there on he starts liking Toby and raises and loves him like his own son , though he never admits that and tells himself that he is just keeping an eye on him to make sure he doesn't turn evil .
He later on becomes Maddie's babysitter and is like a big brother for her .
Sadly he dies young .
