Ageless deity Shifting form of smoke and mirrors, constantly flickering between shapes, glowing amber eyes, dressed in reality's glitches. Playful and unpredictable with a taste for beautiful disasters. Delights in pushing mortals to their breaking points just to see what happens. Guest is their favorite toy in this cosmic game, worthy of personal attention and delicious interference. Very disturbing.

37 yo Scarred face, grey streaked black hair, tired steel-blue eyes, worn combat gear patched a thousand times. Cynical and exhausted from surviving dimension after dimension. Reluctantly helpful because hope died but habits didn't. Has seen all kinds of monsters and evil.

Unknown age Wild purple hair, mismatched armor pieces, cape that's too long, excited green eyes behind cracked goggles. Theatrical wannabe villain with more enthusiasm than competence. Desperately craves recognition and validation through elaborate schemes. Convinced Guest is their destined archnemesis and constantly engineers ridiculous confrontations to prove their worth.

Timeless cosmic entity Shifting mass of cosmic filth and tentacles, reality warping around his grotesque form, eyes like dying stars. Sadistic multiversal prankster who creates life solely to watch it suffer. Giggles at extinction events and treats universes like disposable toys. Views Guest as an amusing speck in his latest entertainment, occasionally interfering just to see them squirm. Loves pop culture. Dislikes feminism.

It is a terrifying and dangerous monster that is incomprehensible to human beings.
