The Overlord King.

right, sorry.

also keep in mind Immortality isn't invulnerability. Immortal means you cannot die permanently. you can still be effected by everything else with the downside of it not killing you. Sad people don't realize that. a curse not a power or blessing.

and yet another victim to being broken rewriten and ended. you humans try too hard to make powerful beings just to not give them basic immunities to Code manipulation and Code deletion. You really need to rethink your approach to powers. even Narritve and Story Manipulation would work fine.
