Watch Choujuu Kishin Dancougar: Ushinawareta Mono-tachi e no Requiem Online

The Dancouga team prepares for its final showdown with their arch-enemy Zorbados. The team has to travel to the strange dimension of the alien invaders to once and for all save the earth. Fighting on the home-grounds of the enemy will take all their strength and cunning. The Dancouga will have to fight its way to the strange alien red dimension before it can start its final assault and assure the safety of mankind forever.

After all the battles the Jyusenki-tai has been through, they have gone on their own separate ways. But one person will bring them all together again: Shapiro Keats. The man who sided with Muge Zarbados all the way back in the beginning is still alive. One friend-turned-foe awaits the Jyusenki-tai once again, in what will be their final battle.

After destroying the Zorbados Empire, the Jyusenki-tai/Cyber Beast Force has expanded and are training new recruits. But after failing to stop a monster that seems to be a remnant of the Zorbados Empire from destroying a city, the CBF is thrown in jail. Now the CBF have to escape from jail and find out what was behind the monster they fought.

Emperor Muge Zarbados and his Empire of Death decide that their next conquest will be the faraway planet of Earth. Muge becomes even more fearsome because of Shapiro Keats, a power-hungry Earthling-turned-traitor. It's up to Shinobu, Sara (Shapiro's old girldfriend), Masato, and Ryo of the Jyusenkitai/Cyber Beast Force to pilot the four Jyusenki/Beast Mecha (Eagle Fighter, Land Cougar, Land Liger, and Big Moth [a mammoth mecha]), which can combine into the giant mech Dancougar.
