I intended to make a story about this, but couldn't really figure a plot. So have the idea and enjoy.

Thirty-Fifth: 

Undertale Multiverse idea: Classic, Fell, and Blue have special abilities. 

Classic, the True Judge: He instantly knows the backstories of every single Sans in the multiverse. 

Fell, the True Motive: He instantly knows the danger rating of every single Sans (In relation to his AU and to the Multiverse). 

Blue, the True Shipper: He instantly knows the ships of every single Sans (and the likelihood) and he can nudge ships along. (To the tune of "When you're happy and you know it") When you don't know who to date, you ask Blue!~ clap clap When you don't know who to date, you ask Blue!~ clap clap When you don't know who to date, and you really want a mate, when you don't know who to date, you ask Blue!~ clap clap

(You can change Blue's True Power to match the level of Classic and Fell if you want)
