Clockwork

Clockwork is the Omnitrix's DNA sample of a Chronosapien from an unknown planet.

Appearance
Clockwork is a robot-like alien with skin that is made of copper with black stripes and a transparent piece of green circular glass, revealing gears inside of him.

In Omniverse, 16 year old Clockwork has a larger body and holes on the protrusion on his head. His head is also restructured a little. The piece of glass is now in the shape of a hexagon instead of a circle.

11 year old Ben's Clockwork has a thinner and rounder head, a white and black shirt, and a smiley face.

Clockwork wears the Omnitrix/Ultimatrix symbol on his chest.

Powers and Abilities
According to Ben 10,000, Clockwork can travel through time.

Clockwork can fire green time rays from his hands or chest which can send people back in time or to age an object/person to dust as seen in Catch a Falling Star.

By rotating the winch on his head, Clockwork has the ability to create a projection of what happened in the past as seen in The Eggman Cometh and in The Beginning of the End.

Weaknesses
Clockwork is not very durable, as Overlord's glove's laser beam could break Clockwork's arm and make him shut down. When Clockwork changed back to Ben from this state, Ben's arm was broken.

Because of his large body, Clockwork is quite slow and low on stamina. Therefore, he tires out quickly.
