Biography[]
Background[]
| “ | It was Vilgax. It was always Vilgax. I was taking him down by myself when they got in the way! My Max? My Gwen? I told them I could handle Vilgax, but they didn't believe me! And they paid the price. So I proved to them I needed no one! | „ |

This Ben was the same as the reboot version of Ben Tennyson. However, Vilgax consistently attempts to steal the Omnitrix from Ben until a particular fight when Gwen and Max try to assist him against his wishes. Tragically, Vilgax uses his optic lasers to destroy the Rustbucket, killing Gwen and Max in the process.
Horrified and enraged by this, Ben uses Four Arms to scatter the Omnitrix, causing an explosion that destroys Vilgax once and for all, therefore avenging the deaths of both Gwen and Max. Ben transforms into Alien X and remains trapped in his powerful newfound alien form. Devastated at the deaths of his cousin and his grandfather, he decides to use his new alien to travel throughout the Omniverse to hunt down his alternate counterparts to make them suffer the same way as him by taking away their Omnitrices, as well as occasionally destroying or severely injuring them.
Prior to the events of the episode, Maximilian Tennyson (an alternate counterpart of Max Tennyson) and 15 year old Ben Prime (an alternate counterpart of Ben Tennyson) have been chasing Alien X down.
Alien X-Tinction[]
Alien X obtained an Omnitrix from an alternate timeline where Reboot Gwen never joins Reboot Ben on a summer road trip with Reboot Max, before travelling to the Reboot timeline. Reboot Ben transforms into Four Arms, Heatblast, Humungousaur, Diamondhead and finally Rath, but those aliens was defeated by Alien X, proving to be too powerful for any of his alien to fight, and ends up losing his Omnitrix to Alien X. However, Ben eventually reobtain his Omnitrix with the help of his family and his other alternate counterparts, who also help him to remove the stolen Omnitrices from Alien X's body. Ben, his family and his other alternate counterparts team up and successfully defeated Alien X with all their efforts. Omniverse Ben used Bloxx to handcuff Alien X after being weakened from having the Omnitrices removed. Alien X finally reverts back into Ben and was taken to the Null Void by Maximilian as punishment for his crimes against other Bens. But also after he pays for his crimes, he will spend some quality time with Maximillian to an endless road trip through the Omniverses.
Trivia[]
- Alien X is the final villain of the Reboot continuity of the Ben 10 cartoon franchise. Omniverse Ben used Bloxx to handcuff Alien X.
- He's essentially an evil Peter Pan; never growing up from being the child he was.
- It's unknown how he could gain full control of Alien X at the beginning, but it's possible his version of Bellicus easily sided with him, due to Ben's wrathful nature pairing well with the fact Bellicus is the Voice of Aggression, which would get past the normal need for voting.
- In a way, he's the stupidest version of Ben Tennyson (not counting Benzarro); despite having the powers of practically a god, it never occurred to him to simply rewind time at the explosion and resurrect his grandfather, Max Tennyson and his cousin, Gwen Tennyson, meaning he went on a crusade to make his family and his other alternate counterparts suffer for no real good reason.
