Plot [1]EditEdit

Season 1[2]EditEdit

The series starts with Ben Tennyson, now 16 years old, who has mastered the powers of the Ultimatrix (a more powerful replacement for the Omnitrix, now able to evolve Ben's aliens) and teaming up with his friends Gwen and Kevin to battle alien threats. But now, Ben faces two problems;

1. A boy named Jimmy Jones reveals Ben's superhero campaign and Ben becomes world famous by kids, but distrusted by some adults, especially Will Harangue.

2. He must battle an evil Osmosian named Aggregor who intends to absorb the powers of five aliens from the Andromeda Galaxy in order to claim the "ultimate prize".

Our story begins when the team fights the first Andromeda alien, Bivalvan, who is stealing parts from a NASA rocket. We learn from Bivalvan that he was captured by Aggregor along with four others as he is intent on stealing their powers for reasons unknown. Aggregor captures Bivalvan again, and he does so with the others, Galapagus, P'andor, Andreas, and Ra'ad. However, Ben's Ultimatrix scanned their DNA and adding them to Ben's alien selection.

Aggregor successfully absorbs the powers of the Andromeda aliens using Paradox's time machine and even killing them in the process, transforming him into a monster similar to Kevin's first mutation. Azmuth explains that Aggregor intends to use his new powers in order to collect the pieces of the Map of Infinity, an artifact that has the power to let you go anywhere. Paradox divided the map into four pieces and separated them. Grandpa Max is forced to be laid off the mission as Aggregor damaged his entire nervous system, and Azmuth has arranged for him to be replaced with a new one. Despite the group's efforts to stop Aggregor, he successfully retrieves all pieces.

Azmuth and Paradox now fully explain what Aggregor's plan is. He is intent on using the Map of Infinity to travel to the Forge of Creation, the place where Celestialsapiens (Alien X's species) are born. He wants to absorb the power of a newborn Celestialsapien, so without the personalities of Serena or Bellicus, he could rule the universe however he wants to. With Aggregor still too poweful for them to fight, Kevin absorbs the Ultimatrix aliens, transforming him into a monster again, now crazier than he was before. Though he does defeat Aggregor, he now leaves the team.

Kevin is now going on a revenge spree on everyone who did him wrong, and also a hunt for power. Ben is willing to kill Kevin, realizing how dangerous he is, but Gwen is willing to help Kevin and cure him of his mutation. Ben goes to great lengths of disagreeing with Gwen about helping Kevin, and eventually leaves her to find Kevin and end him. However, Gwen sees a spark for hope as she enlists Darkstar's help, who reveals he has a piece of the Dominus Librium (an artifact that once cured Kevin of his previous mutation), and with enough power, it could absorb Kevin's power and change him back to normal. The group, with the help of Cooper, build the machine and Kevin does return to normal (Darkstar tries to take it, but Ben stops him). All the power he absorbed goes back to their previous owners and the Andromeda aliens are also brought back to life.
