The Conal Effect

When someone is seemingly absent mentally, and acts like an NPC, but the act is theorized to be an antic disposition, and can destroy the universe if they wanted to.

Individuals seeming to be affected by The Conal Effect tend to secretly quantum jump throughout their surroundings. No mere mortal knows when or how, but the individual somehow ends up behind you.

"Hey where'd this guy come from?"
"Guys, I think he's affected by The Conal Effect."
"Oh we're done bro nice knowing you all"
