Benjamin Kirby "Ben" Tennyson is an alternate version of Ben.[note 1]


Ben is a teenage version of his Reboot counterpart with shaggy hair. He wears a white hooded jacket with two green stripes on both arms and a green number 10 on the right side. He wears brown cargo pants with pockets at the knees and green and white shoes. He wears the Omnitrix on his left wrist.


Compared to the other teenage alternate Bens, Omniverse Ben is notably more cocky. Despite his attitude, however, he is self-sacrificing, wiling to use himself as a shield to protect others, and is a heroic person like most any other Ben Tennyson. His attempts to be friendly to his younger counterparts often rub them the wrong way, despite his good intentions.


Omniverse Ben first appears in Alien X-Tinction, where he is brought to Dimension 27998.3 by Ben and Maximilian to help fight Alien X. When Original Series Ben as Heatblast is having trouble blowing up raining boulders, Omniverse Ben turns into Bloxx to protect him, Ben, Gwen, Max, Maximilian, Ultimate Alien Ben as Ampfibian, and Gwen 10 as Ripjaws.

Ben eventually convinces everyone to fight Alien X at the time. As Bloxx, Omniverse Ben is able to synchronize his powers with his counterparts and remove the alternate Omnitrix from Alien X's left shoulder. After Alien X is defeated, Omniverse Ben states that he was not expecting their enemy to be an evil adult Ben. As Maximilian takes Evil Ben elsewhere, Ben thanks the others, stating that he could not have beaten Alien X without them. Omniverse Ben cockily agrees, stating that he could not have done it without him. He is last seen being shoved into the portal by Gwen 10 before returning to his home dimension.

Powers and Abilities


Ben possesses the finalized version of the Omnitrix. Through it, he can transform into various aliens and utilize their respective powers.

Aliens Used


Whenever the Omnitrix times out, Ben is left powerless until he switches to a new alien form.


Ben 10

Season 5


  • This Ben's design is a stylized version of 16-year-old Ben Prime's occasional appearance in Omniverse.
  • Omniverse Ben's inclusion in the reboot was first hinted by Duncan Rouleau when giving vague hints on what to expect for Season 5.[DR 2]
  • Omniverse Ben might come from sometime after So Long, and Thanks for All the Smoothies, as he is shown wearing the hoodie he gains after recreating the universe as Alien X.
  • Omniverse Ben is shown wearing his hood over his head, something Ben Prime never did on-screen. This trait is instead something Nega Ben exclusively performed.
OV Omnitrix Core AXT.png
  • The square faceplate on Omniverse Ben's Omnitrix is part of the Omnitrix's core and pops up when activated instead of the faceplate sliding upwards to reveal its core like it does in Omniverse , however this is most likely an animation error.
  • The reason why Omniverse Ben used only Bloxx during Alien X-Tinction was due to time constraints and design costs.[DR 3]


  1. Duncan Rouleau claims that the four alternate Bens featured in this special are the same as the Ben Prime from the previous four series.[DR 1] However there are subtle differences between the Bens compared to their Classic counterparts and while these could just be errors, it is never directly confirmed whether or not Maximilian or Alien Force Ben's device can travel through time. As such it is open to interpretation as to whether or not this Ben is Ben Prime. This wiki however, considers them separate characters who are based on the Bens from the series they represent.
