Ben X Slave Quest APK is a game based on a story that started in one of the episodes of the series, where Albedo was surpassed twice by space villain Vilgax after taking Ben Tennyson’s Omnitrix. He transforms into a powerful Ultimate Humongosaur with his own device – the Ultimatrix – and fights all of his alien minions. In the end, he was overwhelmed and – on the show – caught.
At the last seconds, the Alien X was activated instead, and Albedo escaped. Transported to a space between dimensions, he has no choice but to deal with the almighty creatures Bellicus and Serena after they warn him of a mysterious threat that will lead to the end of the Multiverse.
He will need to replace Ben, and make sure everyone thinks he is real! That means playing a hero and earning the trust of those close to real Ben. His cousin Gwen, plumber Rook Shar, chaotic Charmcaster, and a Gwen from an alternate universe seem to be key to saving the world … or dominating it.
