Here are the mutations Kevin suffered in the original series.
Pyronite Kevin
Kevin was mutated into a Pyronite/Osmosian hybrid when he absorbed Heatblast's DNA. Kevin's plan was to move the tracks to have a cash train hit another train, and once they collide, he would take the money. Ben disagrees, saying that it would hurt civilians. Kevin does it anyways, not caring about what Ben has to say. Ben then decides he has to stop him by brute force, so he changes into Heatblast But he wanted four arms. While they are fighting, Kevin manages to absorb Heatblast. Heatblast shakes him off before Kevin can fully absorb the DNA, but he had been on long enough to absorb half of it, making him a Pyronite/Osmosian hybrid.
Powers and Abilities
- Energy Absorption
- Pyrokinesis
Tetramand Kevin
Kevin attempted to use the power of the Omnitrix to get revenge on his rivals. Ben, believing that he should not use his power for the sole purpose of revenge, attempted to distract him as Four Arms but he wanted stinkfly While the two were brawling, Kevin lost his Heatblast abilities, putting him at a disadvantage. Like before, Kevin absorbed Four Arms' DNA and fought back. Only this time, he managed to absorb more of the DNA, making him closer to a Tetramand than a hybrid but the only differance was that he had six arms instead of four. With his two powers, he easily overwhelmed Ben, who reverted to his human form. With his victory, Kevin attempted to take off the Omnitrix. However, due to him pulling too hard on it, he activated the Omnitrix's defense, and it let out a blast of DNA, blowing Kevin away, losing his Tetramand powers in the process.
Powers and Abilities
- Energy Absorption
- Enhanced Strength
- Enhanced Durability
Kevin 11
After Kevin had been defeated by the Omnitrix's feedback pulse, he had discovered that he had absorbed a sufficient amount of DNA from the blast. The Omnitrix had let loose every strand it contained that was not locked, allowing Kevin to switch between any of Ben's ten unlocked aliens, but only being able to access his own human form for brief intervals; putting him in a situation opposite to Ben himself. However, during a fight with Four Arms on the Golden Gate Bridge, Four Arms put Kevin into submission and, at first, looked like he was going to kill him. Instead, he deliberately missed and walked away, stating that Kevin was never worth it. Kevin, however, wanted to continue fighting and became enraged. The rage of an untrained Osmosian, combined with all of the energy and DNA he had absorbed, caused his powers to spiral out of control, causing him to mutate him into a hulking chimerical behemoth fusion of the ten original starter aliens of the Omnitrix, which Kevin dubbed Kevin 11 (due to having all of the powers of the ten Omnitrix aliens plus his own).
However, he had soon realized that he was merely a fusion of DNA, giving him all the combined strengths and weaknesses of all ten aliens. This subtracted the moderate strength of species from intense strength of species, giving him only slightly stronger than average powers, save for the ones that did not compete with other DNA or were otherwise uncompromised by his physical makeup, such as Stinkfly's ability to shoot gunk and Ripjaws' gills (although, he had become too heavy to swim). Vilgax called Kevin 11 "a misshapen chaotic amalgam of creatures from the Omnitrix", his powers weren't as strong as Ben's and only had one-tenth of their original strength (however, in terms of physical strength, he was stronger than Four Arms). However, he is capable of mixing the abilities to create a powerful result, such as using Heatblast's flames and Stinkfly's gunk to form an explosive attack, or using XLR8's speed, Four Arms' strength, and Diamondhead's fist for, as he put it, "one mean punch".
In ...Nor Iron Bars a Cage, it is revealed how Kevin changed back to normal from Kevin 11. When he became a Null Void prisoner, he met another prisoner named Kwarrel, who Kevin 11 soon looked to as a mentor. Kwarrel taught Kevin 11 how to control his anger and powers. Soon enough, he had learned he could do much more than merely absorb and manipulate energy, he found he could do the same thing with matter itself.
