Primary was a superhero who operated in Metron.

He was really a kid called John Harge (pronounced the same way you'd say 'barge' but with an H instead of a B) who was friends wih Metal Boy and others in the L.O.C. (League Of Champions).

He was the proudest of the group, showing off his powers, takin most of the space on the press' photos, etc.... Despite this behavior, Primary was still useful to the team.

The reason he is called Primary is because of his powers. He has fire powers, water powers, and light powers. If you take the colors of those powers, red, blue, and yellow, you get the three primary colors!

Primary and his friends battled crime in Metron, until one day he betrayed the L.O.C. for reasons unknown. His betrayal was stopped before he did much damage, but his treason, along with tensions from others about the L.O.C., caused the organization to close down.
