Aku

Long ago in a distant land... I, AKU, the shapeshifting master of darkness, unleashed an UNSPEAKABLE EVIL! But, a foolish samurai warrior wielding a magic sword, Stepped forth to oppose me.

***SCHHWWWIING***

***SCHWIIIING***

***SCHWIIIING***

Before the final blow was struck, I tore open a portal in time, and flung him into the future, where my evil is LAW! Now, the fool seeks to return to the past, and undo the future that is AKU!

Description
Aku is the main antagonist of Samurai Jack, and is one of the most famous and strongest competitors of Mr. /co/lympus. He attained the third seed in his first two appearances, finishing seventh place in 2018 and losing in the fourth round of the 2020 tournament to the eventual champion Tom Cat.

Outside of Mr. /co/lympus, Aku plays as a gold-medal forward for the board's virtual divegrass team, and has his own goalhorn that is played whenever he scores on the pitch.
