Ultimate Kevin was composed of a larger pool of aliens than his earlier mutations, with multiple parts of his body now being combinations of multiple aliens. His face mostly resembled Jetray's but had Kevin's hair, a patch on his right eye consisting of Swampfire's skin and Humungousaur's eyebrow, and a jaw belonging to Humungousaur that split like Ultimate Spidermonkey. His torso came from Humungousaur but had a backside colored like Jetray. Draped over it was the cloak/set of wings of Big Chill. His right arm mostly resembled Diamondhead's, but with two magenta crystals on his shoulder resembling Chromastone's and a claw resembling Lodestar's. His left arm mostly resembled Swampfire's, but with a metal shoulder spike belonging to Lodestar and a wrist claw belonging to Rath. His right foot resembled Jetray's, while his left foot resembled Rath's. He also had Humungousaur's tail, two of Brainstorm's legs in place of a secondary left arm, one of Spidermonkey's arms as a secondary right arm, and portholes on both his Swampfire-like hand and Lodestar-like claw.
Ultimate Kevin wore Kevin's pants, albeit with tears at the edge of the legs.
Ultimate Kevin's feelings for Gwen prior to his mutation became mixed with his insanity, as seen when he commenting that he thinks she has deliberately avoided him. He also shows anger when Cooper tries to get in his way and tries to kill him as well. Ultimately, despite his love for Gwen, Ultimate Kevin was overwhelmed by his hunger and nearly killed her.
By Absolute Power: Part 1, Ultimate Kevin's self-control is almost entirely overtaken by his insanity, further cementing Ben's claim that Kevin was too powerful for anyone to beat and that "putting him down" was the best option.
In The Forge of Creation, in order to stop Ultimate Aggregor from absorbing the powers of a newborn Celestialsapien, Kevin had no choice but to absorb the Ultimatrix's powers and turn into, as Vilgax would call it, a misshapen chaotic amalgam form of the creatures of the Ultimatrix. This form easily defeated Ultimate Aggregor and drained his powers, reverting him back into Aggregor. After being scolded by Young Ben for his selfishness when he attempted to absorb the Celestialsapien infant, Ultimate Kevin left the Forge of Creation.
In ...Nor Iron Bars a Cage, Ultimate Kevin returned to the Null Void to avenge his former mentor Kwarrel by killing Morgg. However, he simply left when Ben and Gwen intervened and Morgg was brought to justice.
In The Enemy of My Enemy, Ultimate Kevin goes rampant on attacking Argit for all his double-crossing. Fortunately, Argit's ability to turn off his pulse confused Ultimate Kevin into leaving the Plumbers' Academy.
In Absolute Power: Part 1, Ultimate Kevin's instincts have caused him to develop an insatiable hunger for energy and begins draining the life force of anyone unfortunate enough to cross his path, regardless of whether or not they had powers. Ben still thinks that eliminating Kevin once and for all would be the best choice. Gwen, however, sees that the power is controlling Kevin's mind and puts her own life at stake to help Kevin by talking.
Ultimate Kevin admits to Gwen that he retained a single shred of his humanity, which was enough to stay away from Gwen, knowing that his remaining willpower would be overwhelmed by his insanity and that he would end up draining her if he got the chance. Overwhelmed by his hunger, he then becomes obsessed with her life force and powers and ends up tracking her.
Ultimate Kevin was cured in Absolute Power: Part 2, thanks to the efforts of Ben, Gwen, Cooper, and Darkstar. However, Darkstar betrays the team and becomes Ultimate Darkstar by absorbing the powers from the Dominus Librium, which had absorbed all of Ultimate Kevin's powers. Fortunately, Ben anticipated this from the beginning and presses a button that strips Morningstar of his new powers.
Grandpa Max, Julie (wearing Ship), and Ra'ad (accompanied by Bivalvan, Galapagus, P'andor, and Andreas) collectively reveal that Ben's move also returned the powers Kevin collected to their rightful owners and revived the five Andromeda Aliens that Aggregor had absorbed previously.
In Night of the Living Nightmare, Ultimate Kevin appeared in a dream, trying to convince Ben to surrender the Ultimatrix. However, he was quickly defeated and reverted back to normal when Ben transformed into Ampfibian and electrocuted him.
In The Ultimate Enemy: Part 2, Ultimate Kevin appeared in a flashback.
Powers and Abilities
Overall, Ultimate Kevin had access to the abilities of every normal and Ultimate alien Ben had in the Ultimatrix during the second season of Ultimate Alien.[DM 2][DM 3] Over time, he would gain new powers and add onto existing ones by absorbing those of the Plumbers' Helpers, Dr. Viktor, and Stone Creatures.
Ultimate Kevin still retained his normal counterpart's absorption abilities, being able to absorb powers, energy, and matter.[DM 4][merch 1] Eventually, he even became able to absorb power from a close distance away.
Ultimate Kevin had an incredible amount of physical strength and durability, both of which came from a multitude of aliens: including both regular and Ultimate Humungousaur, Four Arms, Armodrillo, Rath, and Way Big. His Appoplexian claw allows him to smash and cut things much easier, shown when he used it to mine rock or slice trees clean off.
After absorbing Alan Albright's Pyronite powers, his fire manipulation and resistance to fire both grew stronger. Kevin began to frequently set his entire body on fire, resist being exploded, and easily walk through blazes.
Besides pyrokinesis, Ultimate Kevin also shared many more of Swampfire's powers, such as controlling plants and generating seeds from which vines would grow.
Ultimate Kevin could fire and manipulate electricity thanks to his wide array of electric aliens' DNA: Transylian; Cerebrocrustacean; Nanochip; and Amperi. His Cerebrocrustacean DNA in specific also allowed him to generate shields made of yellow electricity.
Ultimate Kevin became able to project blasts of mana after completely draining Gwen's Stone Creatures. This also gave him the ability to detect mana, as he could "smell Gwen's mana everywhere" while at her house.
Ultimate Kevin was not always aware of the extent of some of his powers or how to use them. He did not use the powers of all of his DNA samples and had to learn how to use certain powers. For example, he was unaware he could phase through the Rust Bucket 3 until Ben pointed that out.
This weakness also applies to his mana manipulation, as his mana seemed to be significantly weaker than that of an experienced mana user like Gwen. While one orb from Ultimate Kevin was able to overpower a single mana projectile from Gwen, it was unable to thoroughly break Gwen's shield, only leaving minor cracks.
Ultimate Kevin was weak to an Evolved Sonorosian's sonic disks, as Ultimate Echo Echo's "Sonic Doom" attack was the only attack ever capable of knocking Kevin out, and also being one disc blast away from killing him.

- Greg Cipes did not use a filter to make his voice deeper when he voiced Ultimate Kevin. Instead, he just changed his voice.[DM 5]
- The crew went through many design concepts for Ultimate Kevin before settling on the final design.[DM 5]
- Ultimate Kevin did not have access to Alien X's powers due to that form being immediately relocked in the Ultimatrix before the team traveled to the Forge of Creation.[DM 3][DM 6]
- Ultimate Kevin did not absorb Ultimate Aggregor's powers because he needed to, but because he wanted to.[DM 7]
- Ultimate Kevin did not change in appearance when he did so because he only absorbed Ultimate Aggregor's energy, not his genetic structure.[DM 8]
- Aggregor used a machine to change the Andromeda aliens into energy so he could absorb all of their power. This was the energy that Ultimate Kevin absorbed.[DM 9]
- Kevin did not use the same method he was taught to revert from Kevin 11 to get rid of the Ultimate Kevin mutation because he absorbed a great deal more power. It would not have been easy to discharge it, especially when it felt good to absorb more.[DM 10]
- Ultimate Kevin was the Alien of the Month in December 2011.
- However, in Australia, Ultimate Kevin was the Alien of the Month in November 2011 rather than Ultimate Echo Echo.
