They find the hero/heroine in the middle of the battlefield as he/she wakes up from Dee Dee's meddling with Dexter's time travel experiment. In the future, Ben and Numbuh Five are teamed up to help combat the Fusion Spawns at the Battle of Tech Square. However, due to a miscalculation by Mandark, the cannon fire was too late to stop the Terafusers from summoning Planet Fusion and its army to Earth. Ben (once again as Fourarms) then helped defend Dexter's ship against the Fusion Spawns in order to buy him and Professor Utonium time to fire the cannon. Ben was able to bypass Mojo's security system as the Galvanic Mechomorph he called "Upgrade." Despite a Fusion Spawn attack, that part was recovered without a hitch, since Mojo and his minions had abandoned the lair in their attempt to conquer Planet Fusion. Mojo's lair was raided by a team consisting of Ben, Numbuh Two, Bubbles, and Blossom. Unfortunately, two key parts to the EPC were in the custody of both his nemesis, Mandark, and the villain, Mojo Jojo. With the help of Professor Utonium, Dexter developed plans for an Electronic Pulse Cannon to disable the Terrafusers. Although, after his success at saving the universe from the High-breed invasion, his overconfidence caused him to revert to his immature personality.Īfter the first Terrafusers landed on earth, 10 year old Ben (as Fourarms) teamed up with Dexter to defend Foster's Home, Mac, and Bloo from the Fusion Spawn invaders. He has proven to be a capable leader for his team. A common trait people see is that Ben is somewhat not intelligent, though Ben actually proves to be resourceful and cunning when needed, especially when the Omnitrix cannot activate or doesn't provide him with the form he originally wanted. Sometimes, his idealistic nature tends to make him act naive. He will stop at nothing to protect his family or anyone in danger. He also had a love-hate relationship with Gwen in the original series, but they are shown to be much closer in Alien Force.ĭespite his immaturity, Ben is good-hearted, and his actions are motivated above all by a strong and sincere will to help other people. In Alien Force, he acts more mature due to Max's disappearance and the threat of the High-Breed Invasion, but tends to turn back to his original immaturity after it. Ben then took the Ultimatrix which was in the possesion of Albedo, an alien device that allows him to transform into any various 10 aliens found across the galaxy, hence the name "Ben 10." Ben eventually aquires new aliens through unlocking them in the Omnitrix and absorbing DNA along with the loss of Ghostfreak, whose home planet is in an alliance with Planet Fusion.įor most of the series, Ben is portrayed as an immature, sometimes cocky boy who would occasionally take credit he doesn't necessary deserve. As of episode 46 of Ben 10: Alien Force, Ben destroyed the Omnitrix which was on the wrist of Vilgax at the time. He is the only person in the world to be able to use the Omnitrix. Benjamin Tennyson, also known as Ben, is the grandson of Max Tennyson, friend to his former enemy Kevin and twin cousin of Gwen Tennyson.
