NRG (Earth-68)

This is a version of NRG that appears on Earth-68, the universe owned by Dioga beta. NRG is the Omnitrix's DNA sample of a Prypiatosian-B from the Andromeda Galaxy.

Appearance
NRG is a humanoid alien made of pure, red, radioactive energy contained in a heavy, oven-like suit that is capable of containing high levels of radiation and heat.

In John Smith 10, he has his UAF appearance until Omniverse, where he gets his Omniverse appearance. His true form doesn't have a radiation suit.

Powers and Abilities
Same as canon NRG. He doesn't have the ability to get out of the suit at will, though it does break easily.

Weaknesses
Same as canon NRG.
