Ben as Alien X
Ben slams down the Omnitrix's 1.5 dial and is engulfed in a green light.
As the transformation track begins playing, a light green orb, with lightning surrounding it, travels closer and closer to the camera, until it explodes. Ben hovers in the space vacuum, with lots of tiny stars shining in the background. The camera zooms towards Ben's face, who closes his eyes, as many scenes (Ben gaining the Omnitrix, Four Arms fighting Tetramand Kevin, Cannonbolt destroying the Great One, Future XLR8 defeating Exo-Skull, Zs'Skayr erupting into flames, Way Big throwing Vilgax into space, Malware destroying Feedback, Ben transforming into Swampfire, Ben and Reinrassic III working together, Ben using the Omnitrix to cure the Highbreed, Diamondhead defeating Vilgax, Ultimate Swampfire blasting Vilgax, Aggregor absorbing the Andromeda aliens, Ultimate Echo Echo using Sonic Doom on Ultimate Kevin, Sir George defeating Fasttrack, Inspector 13 hacking the Ultimatrix, Ultimate Way Big deflecting Diagon's lasers, Ben stabbing Vilgax with Ascalon, Gravattack defeating Fistrick, Khyber defeating Rath, Feedback destroying Malware, Way Big fighting the Way Bads, Atomix using Nuclear Winner on Negative Ultimate Spidermonkey, Metashift defeating Vilgax, MAL.W.A.R.E. exploding, Ben and Ester dancing, Maltruence breaking the time stream) flash rapidly one after the other. Ben clenches his fists, as the space around him begins to bend and twist, covering him from head to toe. His body becomes more muscular, as small stars align everywhere, with a white outline forming. The camera zooms towards Alien X's head, where three horns sprout out of it and he opens his green glowing eyes. The Omnitrix 1.5 symbol pops out of his chest, as Alien X stands completely still and releases a green energy wave, completing the transformation.
