Janitor Reinhardt, Mei, and Reaper as hair stylists, Smurfette D.Va. Pilgrim D.Va with roast turkey MEKA for Thanskgiving(I still don’t know where that one came from).
I also added some silly details to other people’s ideas. Rocktopus said Sigma as a clown, I said make it Steven King’s IT with “We all float down here Georgie” as an ult line.
Those are just some I remember off hand.
Edit. Found a thread with some of them listed, and linked.
