Character from Ben 10 by Man of Action / Cartoon Network
A living technological alien that can merge with and control any machine, upgrading it far beyond its original capabilities — the only alien that fights by becoming part of the environment.
Upgrade is conceptually unlike any of Ben's other forms: instead of fighting as a powerful alien, he wins by merging with machines and making them dramatically better. A gun becomes a railgun. A helicopter becomes a fighter craft. A toy becomes a weapons platform. The potential scope is enormous and Ben is still working out the applications. The trick is that Upgrade needs something to merge with. On a road with no technology around, he's a blob with an eye. He can also project his eye's laser in a pinch, stretch his body around things, and function as a living computer interface. But mostly, Upgrade shines when there's interesting technology nearby — and the universe has a lot of interesting technology.
A glossy black alien with a single large green eye and a body made of what appears to be liquid circuitry — flowing, adaptive, capable of altering its shape to merge with machinery. Cables and tendrils extend from him when he's interfacing with technology. When merged with a machine, his eye appears on the machine's surface and his circuitry patterns spread across its exterior.
