It's hero time!
~ Ben's catchphrase


Benjamin "Ben" Kirby Tennyson was an ordinary ten-year old boy who looked forward to spending his summer vacation goofing off and playing video games. But his Grandpa Max had different ideas, taking Ben and his cousin Gwen out on a national road trip to see the nation's most famous and quirky sights. It would have been one boring summer if not for a strange shooting star that flew over the Tennyson's campsite. Intrigued, Ben followed the fallen object to its landing site, upon which he quickly found himself forcibly bonded to a strange "watch" that allowed him to transform into ten different alien "heroes". Now sucked into the world of supernatural and intergalactic threats, Ben quickly discovered that this summer was going to be anything but boring.

Stamina: Unknown (Depends on what type of alien he currently is, or in his original form)

Standard Equipment: Omnitrix (Original and Current), Ultimatrix (originally), Skurd (A Slimebiot is attached to the Omnitrix)

Intelligence: Ben is rather disinterested in school and thus is not particularly worldly at first. This flaw was compounded by the fact that he had a short attention span and preferred to enjoy himself and shirk responsibility as any boy his age would. However, he matures and becomes extremely well-accustomed to battling alien lifeforms over the course of his adventures to the point of facing the universe's most vile and powerful villains and coming out on top in the end. As a teenager, he actually attempts to study. He got a C+ on his worst subject, Chemistry after only studying for a few minutes (And likely the 3 hours he had until his exam began the following morning). In addition, he becomes a brilliant scientist as an adult, developing his own Omnitrix systems and even fusing multiple aliens together for various effects on top of handling crime almost entirely by himself. However, he still has his bouts of arrogance from time to time, and occasionally comes off as lazy and reckless.

Weaknesses: All the weaknessess that the Omnitrix has, Alien X cannot fight if his personalities are unable to agree in doing so, but this has eventually disappeared during his battle with the Galactic Gladiator.

Key: Original Series | Alien Force, Ultimate Alien and Omniverse

Notable Attacks/Techniques:

  • Activate Mode: The Omnitrix's default mode, allowing Ben to transform into an alien recorded within for 10 to 20 minutes. However, once this time is up, Omnitrix will go into "Recharge Mode", locking itself down for a minimum of five minutes in order to prevent incorrigible damage to the user's DNA. However, the Omnitrix can instantly recharge in the face of sudden, mortal danger in order to protect its wielder.
  • Capture/Scan Mode: When the Omnitrix detects new DNA not present in its records, it can copy the DNA of the new sample by making direct contact with the alien or by scanning the alien with a visor under the watch's face.
  • Self-Destruct Mode: Ben can order the Omnitrix to destroy itself with the voice command, "Omnitrix Self Destruct in (time): Command code: 000 - Destruct 0". After activation, the Omnitrix charges energy while counting down until it explodes, with the power of the explosion being proportionate to the amount of time spent charging. The Omnitrix can gather enough energy in thirty seconds to blast off the arm of Vilgax, but can unleash a ripple of energy that can destroy the entire universe if allowed to charge for a few days.
  • Master Control: Under certain circumstances, Ben has access to the Omnitrix's Master Code, allowing him to remain transformed indefinitely and transform into any alien in the Omnitrix he is aware of with a simple thought.
  • DNA Manipulation: In addition to allowing Ben to take up the form of other aliens, the Omnitrix can alter the biological makeup of others and repair damaged genetic structures. Ben used this function to cure the severe genetic damage caused by Xenocyte parasitism, removing the parasite in the process. He later applied the traits of numerous aliens onto the Highbreed in order to remedy the genetic stagnation they caused through their own inbreeding.
