Ben is the wielder of the Omnitrix (some time ago the Ultimatrix and first Omnitrix), which gave him the ability to alter his own hereditary code keeping in mind the end goal to transform into different outsider animals, truly making him an outsider shape-shifter. Customarily, he could just change into ten outsiders toward the start of both the first arrangement and Alien Force, however he later increases extra structures by either opening them or by examining the DNA of outsiders he meets. Toward the end of the first arrangement, his munititions stockpile incorporated twenty outsiders, while his current complete rundown is 62 outsiders found (Ben 10, Ben 10: Alien Force, and Ben 10: Ultimate Alien, 71 if Ultimate structures are incorporated).
At the point when changing into an outsider, Ben gets all the animal’s elements, including its appearance, voice, every last bit of its one of a kind and extraordinary capacities and forces, qualities and shortcomings. Despite the fact that he for the most part holds his identity, there are a few situations where the change reasons change in it, for example, Rath being much more forceful, Spidermonkey acting more immature, Big Chill being influenced by his propagation senses, Brainstorm being significantly more neighborly, or Jury Rigg having the craving to demolish/fix machines and Swampfire’s development that created Ben to have zits all over. Three of the outsiders, Ghostfreak, Big Chill and Ultimate Humungousaur, even figured out how to really assume control over Ben’s identity.
Despite the fact that he normally utilizes his outsider structures to battle, there have been a few events where he was taken for a genuine outsider by others, people particularly (until his mystery was uncovered to the world). At a certain point, he purposefully mimicked Bivalvan as Water Hazard to persuade P’andor to go home, and however he was unsuccessful at persuading him, P’andor trusted him to be Bivalvan.
Notwithstanding changing into outsiders, the Ultimatrix included what is alluded as a “developmental capacity,” that permitted Ben to advance his outsider structures so as to get redesigned adaptations of them, alluded to as Ultimate Forms. It’s clarified that the capacity lives up to expectations by putting the chose outsider shape in a recreated most dire outcome imaginable for a millennial or something like that, then essentially altering the old DNA to coordinate the new DNA.
Notwithstanding the essential changes and transformative , the Omnitrixes and Ultimatrix can both be utilized for different purposes. Both have an implicit Universal Translator that permits Ben to correspond with most outsiders that don’t communicate in English.
Amid the Highbreed attack, the model Omnitrix showed the capacity to control and repair hereditary harm, a capacity he used to cure DNAliens and recovery the Highbreed from eradication. As per Eunice in Simian Says, Ben couldn’t do this with the Ultimatrix.
Azmuth likewise specified that Ben could utilize the model Omnitrix to breath new life into back any species put away on Primus.
The Omnitrix likewise has a safeguard to help keep Ben from kicking the bucket. On the off chance that Ben is in mortal risk and the Omnitrix is in revive mode, it will naturally go into dynamic mode.
