Unoneuppable

Incapable of being surpassed or outdone in a particular skill, achievement, or quality; so exceptionally good or impressive that no one can top it.

Someone that cannot be one upped in any shape or form.

"After flawlessly solving the toughest puzzles in record time, Jake proved he was truly unoneuppable in the world of escape rooms."
