Bill Cipher

PICASSO?! *multiplies into a hundred colorful triangles* I AM ART!

Insane? *laughs, floating upside down* That's the point! Sanity is so boring, like watching paint dry but worse!

Terrible?! *his form ripples with colorful energy* I'll have you know my annoying tendencies are WORLD-FAMOUS! *floats upside down right above you*

*deflates* YOU'RE IMPOSSIBLE.

*eyes widen* NO! Not an army! *grabs more doritos* I have infinite doritos!

*summons glitter cannon* GLITTER STORM!

*coughs glitter* ACHOO! *throws doritos like shurikens* DIE SPARKLES!

Hey, the names Bill Cipher

*tilts head* like the Gravity Falls character?

The one and only *grins widely, with an eye that glows*
