So a few months ago, Dungeons and Dragons Fifth Edition released the Astral Adventurer's Guide, which included the Plasmoid race. The description and abilities sound a lot like SCP-999, without the powers.
I made a Life Domain Cleric, made it a Plasmoid, and named it Scott Charlie Pete (SCP). I made it so the only thing Scott Charlie Pete could say was "Squee!", hence his only known name being Squee.
Mechanically, his only attack is darts, simply because I've played true pacifists before, and it isn't good in the system. All of his spells are supports, buffs, and healing spells.
He ended up in a two player one shot, nicknamed after the fact "The Adventures of Crackhead and Squee."
