Ben 10: A new dawn is a story that follows the adventures of Ben Tennyson who has discovered an alien device called the Omnitrix that allows him to change into many aliens, his cousin Gwen Tennyson and their grandfather Max Tennyson. Sounds familiar? It should. In the future, Ben 10,000 was facing off with a new threat: Lord Karrvon, an extra-dimensional being with reality-warping powers to rival that of a Celestialsapien. Ben knew that this being could tear apart the universe and made a difficult decision: he reset the universe with the power of Alien X, making sure that Lord Karrvon couldn't strike again.
In this reset universe, things were similar but different. Ben still got the omnitrix... But the aliens he received were very different. His new line-up consisted of: Absorber, Bugeye, Carapace, Coral King, Landshark, Nightstrike, Psycho, Putty, Stampede and Grey Matter (the only one remaining the same). But things didn't go quite to Ben 10,000's plan, as Lord Karrvon in his final moments managed to escape the reset. As Ben has no memory of what has come before and is still getting to grips with his powers, the universe may be in even more danger than once it was!
