Detailed Information of Superhero
Air-Walker (Automaton) (Earth-616)
Gabriel Lan, an extraterrestrial from the planet Xandar, was the captain of the explorer ship Way-Opener. The ship's mission was to seek out alien civilizations and attempt to establish peaceful relations with them. Lan had previously distinguished himself in Xandar's military, the Nova Corps, and welcomed his appointment to an explorer ship since he was filled with wanderlust and love of open space. Returning from his seven-year tour of duty, Lan was nearing his home solar system when an unidentified craft appeared and teleported him from the bridge of the Way-Opener to the craft of Galactus. Galactus was looking for a new herald to replace the rebellious Silver Surfer and, after scanning Lan's mind, deemed him an appropriate candidate. Hearing Galactus's offer of vast power and unlimited travel, Lan readily accepted and was transformed by a tiny fraction of Galactus's might into the Air-Walker, second of his heralds. After Gabriel Lan was killed by the Ovoids, Galactus transferred the consciousness of his herald into a perfect robotic replica.
