Powers: Magnetism
Bio: Hailing from the planet Braal, Cosmic Boy (or "Cos", as he is more familiarly known) is one of the original Legion members to appear as "The Legion of Super-Heroes". He has absolute control over magnetism and shows often startling prowess at manipulating all things metallic in a way that casual comic fans might today recognize as a kind of riff on the X-Men villain, Magneto. In truth, though, this hero predates the Marvel villain by about a decade.As one of the longest-running members of the Legion, and its frequent leader, his is one of the more developed personalities. Though his personality has fluctuated in each of the major runs of the book, he is characterized with some variation, but he never strays too far from being portrayed as an essentially serious leader--a "straight", earnest, mature figure amongst his more frivolous peers. He is frequently shown to be in an adversarial relationship with Braniac 5. He often displays fraternal respect to Lightning Lad/Live WIre and Saturn Girl. These four may be seen to be the solid leadership core of the group. He has maintained various romantic relationships, but perhaps none as significant as that to the Legion of Substitute Superheroes' Night Lass.
