Ultimate Upgrade is the Ultimatrix's DNA sample of an evolved Galvanic Mechamorph from the planet Galvan B.
Upgrade's body changes drastically after going ultimate. He gains a glowing green symbol resembling a star on his neck, directly below his eye, and the circuit patterns on his body are green. All the black is now dark green. He looks like Malaware's second form.
The Ultimatrix/Recreated Ultimatrix symbol is on his chest.
Powers and Abilities
Ultimate Upgrade has the standard abilities of a Galvanic Mechamorph, including eye beams, elasticity, and the ability to merge with technology. The latter ability has a small twist; unlike most Galvanic Mechamorphs, he permanently absorbs the technology he merges with (as Malware himself put it, technology upgrades him instead of the other way around).
Unlike his devolved form, Ultimate Upgrade has sharp claws that he could use in close quarters.
Ultimate Upgrade is very intelligent, with a lot of knowledge about the Omnitrix. After a battle with Ben Prime as Perk Upchuck, Ultimate Upgrade fixed an error in the Omnitrix.
Ultimate Upgrade is immune to flame attacks, as seen with his battle with Swampfire.
Ultimate Upgrade can be trapped by Diamondhead's crystals.
Ultimate Upgrade is extremely vulnerable to a Conductoid.
