|"That's not what happened at all!"
Kirchonn the Invincible is one of Master Wu's enemies, who once defeated him and his army of Six-Armed Warriors. While Kirchonn's army was imprisoned in the Mount of Shadows, Kirchonn himself was locked in prison along with various other adversaries of Wu, such as Cardinsto and the Time Ninja. They were later freed by Lord Garmadon in a bid to either eliminate Wu or leave him overconfident.
Arriving back at the Monastery that day, Wu would discover this revelation thanks to a note wich give him a riddle: What is red, blue and very, very dangerous? Realizing the answer is a parrot with an ax, Sensei Wu decides his enemy is at Parrot Bay and heads there. Sure enough, he discovers Kirchonn. Declaring that he'll resume his conquest at Parrot Bay, Kirchonn confronts Wu, revealing he has gained the ability to summon an infinite number of axes. Despite his new advantage, however Kirchonn fails to defeat Wu, who uses Spinjitzu to tie him up to the mast of the ship. Begrudgingly accepting defeat, Kirchonn warns Wu that time is not on the latter's side before Wu leaves to defeat his next opponent. Deciphering Kirchonn's clue, Sensei Wu realizes his next enemy is the Time Ninja, a bandit who gained the power to see a second into the past allowing him to predict all of his opponent's attacks.
