Upgrade has a black exterior with green stripes that resemble circuitry all over him. The green circle on his head is his eye, which glows whenever he talks.
In Destroy All Aliens, Upgrade looks the same except for the fact that he has more of a metallic shine, making him look more like a machine.
In Ultimate Alien, Upgrade has green and black stripes where the white was in the original series.
In Omniverse, 16 year old Upgrade wears the Omnitrix symbol inside the ring of his eye and he is more muscular. His circuit pattern has changed slightly. He sounds like teenage Ben, but has a robotic tone in his voice that is similar to Malware's.
11 year old Upgrade in Omniverse looks exactly as he does in the original series, save for a green Omnitrix symbol and his neck being longer.
Powers and Abilities
Upgrade is not completely solid, as he can be both liquid and gelatinous. Due to this, he can reshape himself to let projectiles or blows pass through him by creating a hole in his body at will.
Upgrade can use his internal nanotechnology to merge with and possess any technology by encasing himself over it. The size of the device is not significant and he controls it as naturally as he would his own body. When he merges, he upgrades the technology, making the technology he possess far more advanced and futuristic and causing new features to form on it. It was shown in Road Trip Rumble that Upgrade can reconfigure technology to suit for any situation, like transform the Rust Bucket into a battle armor with an arsenal of heavy energy weapons, or even retractible robotic manipulator arms. Possessing technology allows him to transform it with seemingly no limit, such as merging with a baseball launching machine and turning it into a tripod-like robot that fired a seemingly infinite amount of baseballs, while the moment he un-merged with it, it returned to normal. He can also make his head or his face appear anywhere on the machines he possesses.
Upgrade can also merge with non-electrical machinery, as seen in The Alliance when he merged with a row machine in the gym.
As shown in Side Effects, Upgrade can form energy constructs such as an energy spike, though mostly while merged with machinery and upgrading them into weapons.
Upgrade has the capability to travel through electrical currents, shown in Midnight Madness. He can also phase through most any metal or technology.
Upgrade can gently descend through the air, similar to a parachute. This was demonstrated in Secrets.
Being inorganic, Upgrade is also able to survive in the vacuum of space.
In Battle Ready, Upgrade can make lasers with his hands and cause energy pikes.
Due being made of living metal, Upgrade is able to regenerate himself.
Upgrade is sensitive to electromagnetic pulse/fields and magnetic fields.
In The Color of Monkey, it is revealed that when Upgrade is attached to technology while it is damaged, he will be harmed as well.
