Nebulon possesses a number of super-humanoid powers which draw upon a planetary bioshpere's energy. Since his powers are derived from the life-energy of a world, they wane whenever he is no longer in proximity to a planet.
Enhanced Abilities: Nebulon in humanoid form has super human strength, agility and endurance.
Energy Manipulation: Nebulon can manipulate energy for a variety of effects, including the creation of spheres, shields, or energy blasts.
Teleportation: Nebulon can teleport across the surface of a planet and between dimensions.
Shape-Changing: Nebulon possesses the ability to shape-change into virtually any form. Because the transformation process is so strenuous, Nebulon does not undertake it often.
Nebulon was a member of the alien Ul'lula'ns, a race of six-tentacled, finned, water-breathing non-humanoids, who had begun to deplete the mineral resources of their home world. To remedy the situation, the Ul'lula'n High Tribunal dispatched an undisclosed number of prospectors to locate and secure worlds with the appropriate mineral resources for the race's survival. Possessing vast biosphere-tapping power and able to assume other forms, Nebulon took a glistening golden humanoid form when he neared star systems with humanoid populations. He was not, however, particularly successful at prospecting. Happening upon the misanthropic Hyperion of the Squadron Sinister, who had been imprisoned by the thunder god Thor in a glass sphere floating in space, Nebulon rescued him, and told him of his mission. Hyperion, eager for vengeance against the people of Earth for the imagined destruction of his world, offered to let Nebulon have Earth. Unaware of the alien's true form, Hyperion directed the Ul'lula'n to Earth and had him re-organized Hyperion's one-time comrades, the Squadron Sinister. Nebulon wished to take custody of the world with all of its land masses completely submerged underwater. To effect this, the Squadron members pooled their resources to create a powerful laser cannon capable of melting Earth's polar ice caps. The Squadron member Nighthawk was an unwilling accomplice to the proceedings, however, and took the first opportunity to summon help.
Contacting the Defenders, Nighthawk outlined the nature of the crisis. The Defenders swiftly travelled to Earth's North Pole and engaged the Squadron in battle.
