In appearance, Devin was outwardly indistinguishable from a human. The same is true for Kevin and other Osmosians that are not fully mature (Osmosians live for hundreds of years and it is at least a century before an Osmosian is fully mature, they also grow small horns on their head) and Devin lacks horns on his head (it's possible he has them, but they are hidden in his hair or Osmosians can breed before being fully mature).
He was described and subsequently shown as "energetic" and "likable".
In Max's false memory, they were trying to escape from Ragnarok, a dangerous criminal who steals the energy of stars and sells them to the highest bidder. The key to his ship having been stolen by Devin, Ragnarok was in pursuit to retrieve it. Having managed to render their ship dead in space, Ragnarok boarded and attacked them, demanding his key back.
When none of his or Max's weapons were effective against Ragnarok, Devin was forced to absorb electricity to buy them some time. While Devin was able to retain his sanity (due to his experience), Ragnarok managed to prevent Max from using a Null Void Projector and trapped them both under heavy fire. Devin shielded Max from Ragnarok's attack, buying Max a chance to get his hands on the Null Void Projector and send Ragnarok to the Null Void.
Devin died in Max's arms, expressing that dying to save Earth wasn't a bad way to go. His last request was for Max to tell his wife and son that he loved them.
In reality, Devin Levin never existed.
Powers and Abilities
Much like Kevin, he can absorb energy, whether or not he can absorb matter is unknown.
It was implied by both him and Max that absorbing energy is too dangerous for him.
