The material which would be later known as Isotope-8 was brought to Earth by a mysterious Pulse, a phenomenon which also affected technology worldwide and left strange energy signatures.

S.H.I.E.L.D. weren't the first ones to notice this strange material, and found themselves against Hydra and A.I.M., who were also trying to get it. With the help of an alliance of superheroes led by an Agent, the two terrorist groups were drawn back.

After researching a "mysterious ore," S.H.I.E.L.D. arrived to the conclusion that the Pulse was a charged cloud of an "Isotope-8," this material which was capable of multiplicating people's powers. The Alliance's new task would become that of securing the Iso-8 from supervillains, some of them who would even create their own alliance, a syndicate led by Doctor Doom.

Both S.H.I.E.L.D. and the Syndicate have used the Isotope-8 to create different types of armaments and to empower their forces.

Different types of unstable Isotope-8 would later appear, a green Iso-8; a blue Iso-8 mutated by the Brotherhood of Mutants; a cosmic yellow Iso-8 created when the Phoenix Force interfered in the Pulse's path towards Earth; a red demonic Iso-8 spawned from Hell; an Asgardian purple Iso-8 modified by its contact with the magic of Asgard; a derivated purple Iso-8 developed by Hank Pym; a "chaotic" Iso-8 created by Ultron; a red Iso-8 created from the demonic Iso-8 synthesized by the power of Tony Stark's arc reactor, and a violet Iso-8 variant created by Wonder Man.

After consulting his mentor, Doctor Strange discovered the Iso-8 might be native of Earth, and that emanations similar to Iso-8 were detected by the Ancient One in the 18th century.[1]


The true nature of the Isotope-8 is unknown. Mutable at a subatomic level, the Iso-8 attaches itself to the essential characteristic of a material it touches and intensifies it. Accoring to Otto Octavius, the Isotope-8 can be considered "the perfect catalyst," although Reed Richards has stated it is not because, unlike catalysts, the Isotope-8 changes itself.

If the Isotope-8 is put in a crystal array to focus a laser, it makes the laser have more focus. If it's put in an electrical field, it magnifies the charge and the momentum of electrons, and becomes magnetic. If it's part of a plasma, the plasma gets denser, hotter and more powerful. Mr. Fantastic has studied the reactions of Isotope-8 with heat, electricity and magnetism, and stated that in those areas, the Iso-8 is an "energy intensifier the likes of which I've never seen."

Hydra has managed to condense data down to binary code and transmit it to limbs and muscles via Iso-8, allowing themselves to create almost perfect replicas of the Avengers from footage of different heroes in action.[1]
