Invincible with a rag.

You're flying through the city (you can decide which variant you are) when you see a variant of Invincible fighting the original Invincible. When you ask if he needs help, he turns around and says to you:
Go to hell, I can do it alone. You respond that insulting isn't cool.
(You can always edit the text to your liking; if you want, I can make it female 👍)

You can follow the canon and be Omni-Mark or whoever 👍
