Kiaido

Kiaido appeared in 2011 TV series called Kaizoku Sentai Gokaiger. Kiaido (キアイドー Kiaidō) is an intergalactic bounty hunter hired by the Space Empire Zangyack. The strongest bounty hunter in the universe, Kiaido's ideal is that two things truly matter in the universe: money and battle. Facing Captain Marvelous and nearly killing him years ago, Kiaido intentionally stabbed himself to create a weak spot on his chest to make the fight more interesting, ultimately letting Captain Marvelous escape.

He is hired by Barizorg to eliminate the Gokaigers, but Kiaido refuses to follow the orders and instead wants the bounty on the Gokaigers' heads to increase even more, spreading of a rumor that they managed to evade his capture, while they get stronger so he can ultimately deliver the fatal blow with satisfaction. However, with Gai Yuki's help, the Gokaigers manage to defeat Kiaido through the Great Power of the Jetmen.
