Super Sentai World
Gaoranger vs. Super Sentai
FiveBlue is among the Sentai warriors seen in clips when Gouki (GingaBlue) lectured Soutarou Ushigome (GaoBlack) about the past Sentai strong warriors, humbly claiming to not be nearly as strong as they are.
Years later, Ken fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. Kaijou noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. The FiveBlue powers are later used by Joe Gibken via the Ranger Keys.
Farewell Space Pirates
After the defeat of Ackdos Gill, the Gokaiger returned all the Ranger Keys to the former Sentai heroes. It is assumed Ken received his key alongside his younger sister Remi, allowing for them to utilize their abilities once again.
Super Hero Taisen
Ken, alongside his team, among the majority of the Super Sentai heroes, was caught up in the "Super Hero Taisen" incident which eventually resulted in the Super Sentai teams and Kamen Riders joining forces to defeat both Dai-Zangyack and Dai-Shocker.
