potent hemlock
Here the antitrix was given to an 11 year old Kevin by malware after he’d already mutated. The device stabilized his mutation by seperating the different genomes in his body and allowing each one to be specifically selected for use at any time, with his human form becoming the 11th transformation.
Additionally, kevins abilities in this AU allow him to alter his DNA for some light shapeshifting, so he’s made a few adjustments to each of his forms, turning genes on and off and reusing parts of the genetic code of each alien in different areas in an attempt to make the aliens “cooler.”
