The Ultimate Combination!! BlackZarak, the New Lifeform

After freeing Shuta, Ginrai and the other Cybertrons know that now that they've finally located the Destron base, they must destroy it. They assemble a strike force, led by God Ginrai and Grand Maximus and prepare to take down the base. Cancer and Clouder guide the Cybertrons through a gap in the Destrons' radar detection net, but the Destrons have a new system and launch a counter-offensive with the Seacons and Pretenders. Fortunately, Grand Maximus is more than enough to handle King Poseidon, while God Ginrai handles the Pretenders. Lord Z reveals his true form and merges with Black Zarak, who traps the Cybertrons at the bottom of the base. Overlord then plants some bombs to blow up the base entirely, and God Ginrai has to convince Wilder and Bullhorn to leave before the whole base is destroyed.
