On his eighth birthday, Clark dons an indestructible costume woven by Martha from the Kryptonian blankets that accompanied him on his journey to Earth. He becomes the costumed hero Superboy, the first superhero of Earth-One. Around the same time as his public debut, Superboy learns of his Kryptonian origin, and several weeks later, he gives reporter Perry White the exclusive story about his alien background. Though most of Superboy's early adventures occur in the vicinity of Smallville, he becomes famous for his superheroics around the globe. Superboy's status as both Smallville's hometown hero and as a national/global hero are reflected in the emergency-signal system that he establishes with Chief Parker of the Smallville Police and the President of the United States. As Superboy repeatedly ventures into interstellar space, his super-heroics also bring him fame on other worlds.
