The Ultimate Battle (Unlocked)

The Ultimate Battle is the 27th episode of Ben 10: Unlocked.

Story
The future Ben Tennyson, now 63 years old, has been retired. However, Praxiss' son, Raxiss, has seeked revenge against Ben for trapping his father in prison. Reluctant to fight against him, Ben says that he doesn't accept the battle. Unfortunately, Raxiss then begins to threaten the whole earth with his own Ultimatrix, and then used it to attack the earth with his clones. Ben is now forced to fight again one last time.

Ben encounters Raxiss in the desert, and then begins a battle with their Ultimatrixes. Ben and Raxiss create their own clones thanks to Echo Echo, and soon releases an all-out war.

The original Ben and Raxiss fought against each other while the clones were fighting theirs. Ben has a tough time fighting him, and eventually almost gets defeated. However, he was forced to use his last resort: Alien X. Being retired, the two keys of Alien X are both his, and so decides to use him. Convincing the two to make Raxiss disappear was very hard, but eventually he was able to say something to convince them, and Raxiss and all his clones just disappeared due to his power.
