In appearance, Devin was outwardly indistinguishable from a human. The same is true for Kevin and other Osmosians that are not fully mature (Dwayne McDuffie confirmed that 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 mature). He also spoke with a notable English accent.
Devin deeply loved his family was very self-sacrificing and considered the planet Earth to be his true home.
Devin's background has not been touched-upon much, no details have been revealed about his life before his career as a Plumber, and no mention of his family other than his son and his wife has been brought-up yet.
As seen in the flashback in Vendetta, Devin and Max were trying to escape 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 the Earth wasn't a bad way to go. His last request was for Max to tell his wife and son that he loved them.
