I'll start

I have this OC called Gavin who always leaves a positive impression on people no matter how grand or itty-bitty.

However this works on /anything./ So much so, he can use this passive to avoid all forms of conflict, including and not limited to a Karren in a shopping mall, an aggressor at a bar and an eldritch cosmic horror monster because "Oh, that's gavin, he's chill"

Lane is a close second due to how actually strong and overwhelming her strength and aggression can be when pushed to the limit.

Also you GOTTA be OP to last 5+ years in the fast food industry.
