Upgrade can use his internal nanotechnology to merge with or control any technology within reach by spreading over it. The size of the device is inconsequential, and he controls it as naturally as he would his own body. When he merges he upgrades the technology, hence his name. 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 plasma weapons. Occasionally he can merge with organic life, as long as there is technology integrated within them, such as with Rojo and Rex.
Upgrade has displayed the ability to launch a powerful green plasma blast from his eye.
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.
Upgrade cannot possess natural creatures.
