Chronosapien

Chronosapiens are a species of biomechanical lifeforms. They're robotic, metallic and appear to be more machine-like than biological.

Appearance
Chronosapiens are large, round semi-humanoid aliens, made of copper and have a translucent window on their chest which displays their innards, which appear to be various gears. They have a round, short head with a semi-circular appendage on top, greatly resembling a wind up key. When moving, Chronosapiens produce gear-like sounds.

History
According to Ben 10,000, at some point during the Time War, the Chronosapiens went rogue.

Powers & Abilities
Chronosapiens are capable of time-travel, and can display events that have happened in the past by rotating the appendage on their heads, which produces a light. This light covers the area and displays all objects and movements in the past as holographic images.

Also, they can slow down time, which makes them look like they are fast when they're actually really slow.

Chronosapiens can use each other's Chronosapien keys, but they won't have their true resonance.

Weaknesses
Chronosapiens appear to be fragile, and easily damaged.

Their metallic bodies can be broken by sufficient force, and they can fall into a powered-down state in which the light in their torso goes off and they cease moving.

They are slow runners and tire quickly.

Use of their powers create a ripple effect which can be sensed and reversed by another one of their own species.
