Sure I'll be the devil that sounds fun.
You "be" the devil! Being the devil seems to actually change your metaphysical properties some, making you no longer omnibenevolent but instead "mostly" malevolent, with a purpose of inflicting meaningless suffering on the world! Yay!
Besides that, you are a red humanoid with horns and a tail in the mostly-void. There is a World full of BAD DEMONS you could probably boss around. Maybe.
EXIST
[1]
You unexist. Which is basically the same as existing but, you know, the opposite of that. It turns out that most things are basically just their own opposites, including states of being.
Whisk the Non-omnipotent with the Existing, let sit in the freezer and bake into mortals in 100 years.
[2]
You try to whisk the WORLD, but the demons get mad and latch onto your whisk, creating too mush drag to use it efficiently!
Offer kitty a blob of Dark to play with. While it’s occupied, begin shifting my elemental weight around—gathering Hot at the center and relegating Cold to the periphery.
[4]
Kittytac isn't in this game! You give Cat some dark blobbyness, though.
Pumping Hot to the center of the mass seems to work, creating a dense center of utmost heat. It seems to glow... with a GLORIOUSLY INCANDESCENT light!
Quickly steal some hot from the blob
[3]
You take some of the hot, but it's really just a Warm.
