more art of the silly guy by meeee

they tried, he just snapped his fingers and evaporated them all (similar to what he did in the ep Weridmageddon when Time Baby's whole army came)

That makes him anti-memetic, which means he defies the usual laws of how the world works. The SCPF has reality anchors at their sites which keep anti-memes from disrupting the fabric of reality during a breach. All they have to do is lure him to a facility and the reality anchors will do the rest.

erm, about that, he's kinda stuck in Theraprism rn, so SCPF gotta break in there, deal with many other evil imprisoned therapy-needing enities, and also deal with The Great Axolotl the most powerful being in all dimensions and multiverse, to get to Bill Cipher and even then if they captured him, he can just escape into the minds of someone and possess them. or he an just leave that dimension. he can see what ALT dimension and can go into the ALT dimension too. honestly I think he was also playing with Dipper and Mabel and that's why he lost

Just saying, they'll find a way eventually. The SCPF has literally contained gods, demons and cosmic beings within its confines.

well I hope they never find ol' billy :<
