The Ego Flaunt

For every molecule of water in their body, they have two bits of their own being.

The one who believes they're better than everybody and look down upon them thinking accordingly. They talk to others condescendingly as if other people aren't worth the "privilege" of being in their presence, disregarding all who want to prove themselves. However, if whoever wants or needs to show the Ego Flaunt is trying to do so for plot-important reasons, the Flaunt will allow the other to proceed, pushing aside their beliefs on how no one is worth their time. If the Flaunt is ever defeated in anything, they would hardly believe what happened and demand that they have a rematch with whoever "ruined" their reputation.

If the Ego Flaunt plays sports, they may be a high-ranking player with a next-to-perfect record with hardly any defeats if any at all. They cockily mess around with the equipment they hold (e.g by twirling a tennis racket around with their finger through a hole in the strings, swinging a baseball bat at an imaginary ball, etc.) while they play as they could (or at least believe they could) easily do so and still win. If somebody challenges them, the Flaunt will do their trademarked talk-down before either telling them They Suck and denying them or accepting them only because the Flaunt had nothing better to do or wants to show how weak the challenger is.
