Bio-Spheric Energy Manipulation: Nebulon could manipulate the biospheric energy of planets at Unearthly rank. His power stunts included:
Energy Bolts: Nebulon could project energy blasts of Amazing intensity with a range of five areas.
Force Field: Nebulon could create a protective energy shield at Incredible rank against all attacks.
Force Bolts: Nebulon could project concussive force bolts at Shift-X rank. Nebulon’s force bolts had a range of 10 areas.
Shape Shifting: Nebulon had the ability to shape-change at Monstrous rank into any form. The transformation process was very strenuous, though, requiring an Endurance FEAT roll to remain conscious. Any time Nebulon’s Health dropped by more than 50 points in a single combat round, he had to make an Endurance FEAT roll or revert to his normal form.
Teleportation: Nebulon could teleport with Monstrous rank ability for a variety of effects. His power stunts included:
Teleport-Self: Nebulon could teleport anywhere on the surface of a planet.
Teleport-Others: Nebulon could transport others either across the planet or across the dimensions with a Psyche FEAT roll.
Gateway: Nebulon could travel to alternate worlds in parallel dimension
If Nebulon were to go without contact with a bioshpere long enough, his power level would be no more than that of a normal human being.
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 homeworld. 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 forhte race’s survival.
Possessing vast bioshere-tapping power and athe ability to assume other forms, Nebulon tool a glistening golden humanoid form when he neared star sytems with humanoid populations. He was not, however, particularly successful at prospecting. Unexpectedly, Nebulon came in contact with the misanthropic Hyperion of the Squadron Sinister, who had been imprisoned by the thunder god Thor in a glass sphere floating in space. Upon rescuing him, Nebulon told Hyperion of his mission.
Hyperion was seeking vengence against the people of Earth for the imagined destruction of his world, and he offered to let Nebulon have Earth. Unaware of the alien’s true form, Hyerion directed the Ul’lula’n to Earth to reorganize Hyperion’s one time comrades, the Squadron Sinister. Nebulon wished to take custody of the world with all its land masses completely submerged under water. To effect this, the Squadron members pooled their resources to create a powerful laser canon capable of melting Earth’s icecaps. 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 and they swiftly traveled to the North Pole to engage the Squadron in battle. In the course of events, Nebulon expended so much energy that he lost control of his humanoid form and allowed his allies and enemies to see his true self; a sight that dismayed even his allies. Nighthawk seized this moment of confusion to train the laser cannon on Nebulon, who seemingly imploded, taking along his three Squadron accomlices.
In actuality, Nebulon displatched himself to the aquatic extra-dimensional world of Zaar, inhabited by a race of philosophers called the Ludberites. The Ludberites explained to Nebulon the essence of their philosophy-that it is the obligation of higher beings to improve the lot of their inferiors. For unknown reasons, Nebulon took this philosophy to heart, servedd his loyalties to his people, and abandoned his original mission to instead save the beings of Earth from their own innate foibles. Returning to Earth, Nebulon assumed a less-imposing human guise than before and started the movement called Celestial Mind Control that Promised to liberate the powers of the human mind but that actually robbed its participants of free will.
As Nebulon spread his movement across the world, the Defenders eventually tried to thwart him. In defenses, Nebulon dipatched some of the Defenders to another dimension to prevent their interfearence. At the same time, the Headmen, a group of renegade scientists, undertook their own scheme to gain worldwide political power. Soon Nebulon and the Headmen found themselves working at cross purposes. After months of effort, the Defenders managed to expose the Headmen’s political machinations and to convince Nebulon it was a hopeless task to force humanity to better itself. Nebulon abandoned his mass movement and disappeared.
When the Tribunal of Ul’lula learned of Nebulon’s interfearence in Earth culture and abandonment of his mission, it tried and convicted Nebulon for treason against his race. But before he could be taken captive, Nebulon fled into Earth’s ocean where he used his shape-changing abilities to assume the form of Lady Dorma, the deceased bride of Sub-Mariner. Convincing the Atlanteans that Dorma had survived, Nebulon used her popularity as wel as his own powers to convince the Atlanteans to attack London. The Defenders then got involved since the Sub-Mariner was one of their original members and uncovered Nebulon’s deception. Soon afterwards, an Ul’lila’n starcraft appeared and took custody of Nebulon, who was sentenced to be stripped of half his biospheric power, entrapped within his humanoid form, and exiled on Earth. The Tribunal suggested to Nebulon that he commit suicide, the noble alternative to disgrace according to his culture, but Nebulon flately refused. Learning of Nebulon’s dishonor, Nebulon’s wife Supernalia traveled to Earth to force him to take the honorable action.
Nebulon had, in the meantime, made his way into the ranks of the Avengers with the hidden goal of using his technology to siphon power from them to replace that which he had lost. Supernalia enlisted the aid of the Defenders, and soon the two teams of champions were manipulated into battle. By the time Nebulon’s motives were revealed, the Earth heroes were already being drained of their energies. Supernalia was made to realize that her actions on Earth also constituted a violation of her people’s ethics, so she chose to comit suicide. In trying to stop her, Nebulon fell victum to the same energy draining ray that was killing his wife. As Nebulon died, he admitted that at last he was actiing honorably. The Avengers and Defenders buried the aliens where they died, in the snowy Himalayan mountains.
