Ben 10 Wiki

Bootleg is the Antitrix's DNA sample of a mutant Galvanic Mechamorph/unknown hybrid and Kevin's equivalent to Upgrade.


Similar to Upgrade, Bootleg takes the appearance of a black humanoid made of liquid metal. However, he has blue geometric stripes visible on his body. His blue shoulders have two orbs, and his back sports two spiked spheres. The red dot on the front of his head is his eye. When he becomes smaller, he has less circuitry on his body and a second red dot in place of the Antitrix.

The Antitrix symbol is located on his chest.

Powers and Abilities

Being part-Galvanic Mechamorph, Bootleg shares many of the same abilities as Upgrade, such as technological possession, elasticity, and enhanced flexibility. Due to the alterations Kevin made to the Antitrix, Bootleg is most likely much more powerful than Upgrade.

Bootleg can merge with technology that is already merged with another Mechamorph, such as when he merged with the Rustbuggy while Glitch was already merged to it.[1]

If Bootleg's body is damaged or taken over, he can become a smaller form, ditching the rest of his body. The body can then continue performing its own actions independently, even after Bootleg has timed out, and can also be merged back into himself.[1]

Seeing as how Upgrade was able to upgrade the Omnitrix to permanently enhance his other aliens, Bootleg could most likely perform the same activity too, although his DNA pod would probably be destroyed in the process.[2][3]

Due to being made of living metal, Bootleg is able to regenerate himself.

Being inorganic, Bootleg is able to survive in the vacuum of space.[4]

Bootleg can terraform a planet's terrain to his own liking, allowing him to manipulate the rocks for offensive combat , as demonstrated by AntiVilgax.[5]


Being part-Mechamorph, Bootleg shares many of the same weaknesses as Upgrade. For example, he is vulnerable to the electrical attacks of a Fulmini.[1]

Bootleg can still sustain damage from attacks on whatever object or technology he is merged with, as seen when Rath attacked Vin Ethanol's car whilst he was merged with it.[6]

Due to Kevin's alterations to the Antitrix, Bootleg is too powerful for the inexperienced Kevin to currently utilize to the fullest. For example, Bootleg accidentally gave Xingo a power-up by mistake whilst being merged with a TV.[7]

Bootleg is a word describing an illegal recreation of a certain object and also a type of illegal download such as pirated music or pirated music videos. This is a reference to how Bootleg, as well as the other Antitrix aliens and the Antitrix itself, are copies of the Omnitrix and its aliens.


  • The layout of Bootleg's circuitry loosely resembles Ultimate Echo Echo from the Classic Timeline.
  • Bootleg shares similarities with various Mechamorph characters from the Classic Timeline.
    • Firstly, he is a mutant Mechamorph like Malware.
    • Secondly, he is an alternate counterpart of Upgrade with a blue color scheme like Techno-Bubble and the Retaliator Armor.
    • Thirdly, he speaks with a voice that is essentially Kevin's voice through a speaker, similar to Upgrade's appearance in Framed.
    • Lastly, he is a Mechamorph hybrid like Uprigg.
  • When Vilgax removes the Antitrix from Bootleg, forcing the latter back into human form, the animation is similar to how Vilgax removed Gax from the Omnitrix in Omni-Tricked: Part 3.
