The 2003 Teen Titans series jumped right into the action; the series premiere opens the show with the fully formed and thoroughly trained Titans battling formidable enemies employed by Slade, Robin's arch nemesis who is building an army to take over Jump City. Opening Teen Titans with the team already a well-oiled machine with good control of their powers leaves little time to delve into the origins of each member's ability- at least at first. Throughout the series, a combination of flashbacks, reminiscing, and the unexpected arrival of people and things from the Titans' past slowly reveal the team's fleshed-out beginnings.
