Feedback is a lanky bipedal alien. He has one green eye with a dark green vertical pupil. His body is green and black. He has two tentacles resembling power cords on his shoulders with large plugs on the ends and a long black tail. He has golden battery bolt-like appendages on his forearms, hips, and shoulders, and has hollow battery-like fingers. He also has pointed feet.
The Omnitrix symbol is located on his chest.
- Energy Absorption- Feedback can absorb various types of energy from the holes in his fingers to a limited extent.
- Energy Release- Feedback can release energy stored in his body from the plug-like tendrils on his shoulders.
- Radio Signal Sensing- Feedback is able to sense nearby radio signals using his tendrils.
- "There's too much energy to absorb. I'm gonna eject it upwards."
- Limited Energy- Feedback does not have limitless energy; though the Omnitrix automatically provides him with some energy, this can run out, in which case he will have to recharge because the energy within him will deplete with use.
- Energy Absorption Limit- Feedback has a limit to how much energy he can hold at once. Absorbing more energy past this limit requires him to discharge some energy first.
- Vulnerable Tendrils- Feedback's tendrils can be easily pulled on, causing him great discomfort and leaving him stuck in place.
In Chapter 2: The Lonely Ghost (Page 5), Feedback appeared in a flashback with other aliens all holding the Anihilargg.
