Lalo Muldroon, a.k.a. Micro Lad, like Shrinking Violet hails from the planet Imsk. Like all Imskians, Lalo possesses the ability to shrink to a microscopic size. He came to Earth to apply for membership of the Legion of Super-Heroes. Lalo failed the audition. He then joined with other rejected Legion applicants to form their own team known as the Legion of Super-Rejects. The team formed to show their superiority to the Legionnaires whose powers matched their own and were preventing them from joining the team.
