Super Hero Taisen (originally based on the film of the same name) is a tokusatsu-based RPG, much in the same vein as Henshin Heroes, and it has a very similar setting. Unlike Henshin Heroes, Super Hero Taisen has so far had an episodic format, with only interactions between the characters linking the episodes of the roleplay together.It has a lot more expansiveness with it's hero choices, allowing toku-like heroes from anime (namely from Tatsunoko works and Tiger & Bunny) to be played along with the more traditional selection of Kamen Riders, Super Sentai, Power Rangers, and Ultraman.The game is defunct, though members have started a similar game with many of the same characters at Heroes' Carnival.
Action Girl: Manami Mizushima, Yuki Kashiwagi, Atsuko Maeda, Nemo, Rebecca Valiant, and the list continues to grow.
Continuity Reboot: The original site was made around early 2012, the same time Kamen Rider X Super Sentai Super Hero Taisen (the roleplay forum's namesake) was released, and even had a similar plotline. The site was abandoned not long after its creation, but it was rebooted by the original creator of the forum, and given a new mythos.
