Power RedKing パワードレッドキング

Red King reappeared as Powered Red King (パワードレッドキング Pawādoreddo Kingu) in episodes 3 and 12 of the series Ultraman: The Ultimate Hero.

In this series, there are two Red Kings (a female, colored the traditional tan, and a male, red) In their debut appearance the female is seen mostly, attacking Chandora, Pigmon, and WINR before facing Ultraman Powered; she calls out to her male and the two monsters briefly double-team Powered. After being dazed by WINR, the female Red King wanders off a cliff to her doom, which leaves her mate in sorrow and loss. Ultraman Powered allows the male Red King to live, feeling sympathy for the monster.

Later around the end of the series, a male Red King appeared and was quickly killed by the Alien Baltan's version of Dorako. It's unknown if this is the same Red King from before or not.
