Aran Ryan is an Irish boxer from Punch Out! who is known for his cheating habits, unstable personality and aggressive nature both in and out of the ring - making him arguably more antagonist than the other boxers in the game. Although most of the boxers in the series use outlandish powers that would not be allowed in real-world boxing Aran Ryan is shown to be a prolific cheater even by the game's standards and is also fairly malicious, especially in his second fight.
Aran Ryan is also cemented as a "heel" (sports-based villain) due to the crowds turning on him and throwing bottles and food at him, to which he threatens them with physical violence due to his hot-temper.
It should be noted that in his first appearance, Super Punch-Out!, he was not evil and is the only boxer with no clear personality to speak of.
- Aran Ryan is the only opponent in Wii's Punch-Out! that cheats, who breaks the 4th wall. If Aran Ryan defeats Little Mac during the Major Circuit, he celebrates his victory, by shacking the ropes while acting crazy, grabs the camera, and headbutts it, breaking the lens.
- He is a rare example of a villain who was not evil (in any ways) in the original incarnation (which is Super Punch-Out! for SNES) but became a villain in another incarnation (which is Wii's Punch-Out!).
- He, debatably, is the only boxer in Punch-Out! to crossed the MEH due to the fact he brought a weapon in a boxing match.
