They'd probably get along pretty well ngl

I'd love to see that

It would be pure evil laughter

naw we done for, dawg-

Bill SOLOS

Ehh

Although he did destroy his universe we don't really know if it was instant or if it took him a few months. Cyn on the other hand dealt some pretty serious damage to copper 9 in just a couple minutes

Bill can read minds, shape-shifting, and even bend reality to his liking cyn only has telekinesis which Bill also has

Cyn can also shapeshift (technically) using her holograms

She also has mind control since she not only took control of Uzi, but also Nori and technically J

Since Bill can bend reality can do the same he can create life or matter out of nothing. Can Cyn create an entire pocket dimension used as a prison for someone? NOPE but Bill can

I didn't even mean for them to fight lol

Weirder-9!

We'd be screwed if they team up

They’d be working together no doubt

the universe would have a chance of cracking in half if they fought

Bill would invade Cyn's "mind" and they would be unstoppable, unless someone showed up with a quantum destabilizer gun

Can he even invade machines?

they would fuse and look awesome

But bill cipher has only been shown to be capable of invading minds, not computers. Cyn is a computer program, after all.
