Nick Brain didn't really do a part-time committed job as a teenager before going into the J. For the most part, Nick was either training or playing games sch as Street Fighter in his off time. On occasion though, Nick would do odd jobs at his local rink in the late summer/early fall, helping sharpen skates, tape up sticks, fuel up the Zamboni with siphoned gas, fix the demonic machinery that provided power to the arena, standard stuff. In exchange Nick would get some free ice time to work on his skating, shooting and stickhandling. Occasionally Nick would also get a money handshake of $20 from the arena owner for his efforts.

Nick also did occasional garden work odd jobs (paid in cash) for his next door neighbour, Damian Wayne. Damian is also the son of Bruce Wayne, the CEO of Wayne Enterprises, a company that Nick's mother works for. Damian paid Nick pretty well, although there was a minor misunderstanding when Nick Brain accidentally found a prototype grappling hook shooter, set it off, and broke a window with it.
