Zhang Lu

Zhang Lu aka Legend Hero Yu Ji is a blind fortune teller who uses his Legend Hero powers to brainwash people into displaying their hidden or darker sides and an antagonist in episodes 15 and 16 of the Korean Tokusatsu show Legend Heroes.

History
At some point Zhang Lu received a Legend Changer and the Yu Ji Hero Piece.

Zhang Lu first appears when he hypnotizes Tao Qian into becoming an unrepentant and greedy thief. He later hypnotized Mi Zhu into being a love-crazed maniac for Gongsun Zan. He was soon tracked down and confronted by Liu Bei, who transforms into Legend Hero Guan Yu to fight him, but Zhang Lu managed to outmaneuver him and get away.

He later encountered Cao Cao as well and the two fought. Realizing Cao Cao was much stronger than him, Zhang Lu teleported away.

Returning to his fortune teller stand, Zhang Lu realized he misplaced his cane and began grasping around for it. His Hero Piece tried to tell him where it was but Zhang Lu got mad at him for "looking down upon him", going into a rant about how people weren't trustworthy and how he couldn't trust anyone.

Zhang Lu eventually has a rematch with Liu Bei and was defeated by him. After having his mecha destroyed in his Final Battle with Liu Bei, Zhang Lu's Legend Changer was damaged by Cao Cao. Zhang Lu asked Liu Bei to become the new Warlord for his Yu Ji Hero Piece, expressing regret at how he had treated it, but Yu Ji refused to have another master, instead choosing to stand by his Warlord until the end.

After being disqualified from the Dream Battle and forgetting about it, Zhang Lu was seen being helped up some steps by a group of kids.
