Origin

Long ago in the Negitive Zone, when the Tyannans seeded life spores on barren planets, one of their ships got hit by a meteor and was sent onto the volcanic planet Arthros. Before dying, the crew released spores. Many years later, one of the spores evolved into an insectoid creature. Due to a mutation he had a high intellegence. He found a Tyannan starship wreckage and used a special helmet to transfer all information about the advanced Tyannan technology. This caused him to grow stronger and smarter, he also gained a "Cosmic Control Rod" and body armaments. The creature became known as Annihilus and he set out to destroy anything that was a threat to his existance. He planned to conquer or destroy all planets nearby Arthros. Other creatures came from the spores as well, but Annihilus used his power so he would rule above them.

Early Encounters

When Sue Storm was having cosmic ray-related pregnancy complications, the remaining three went into the Negitive Zone to find anti-particles that could treat Sue. Annihilus's minions captured Reed, Johnny, and Ben, but the three managed to escape with the cosmic control rod. After siphoning off the needed particles and returning to earth, they returned it to the Negitive Zone. Annihilus invaded the Microverse, sending his minions to conquer in his name. Psycho-Man tryed to stop the Insectovorids, but they were emotionless so they were immune to his power. Psycho-Man had no choice but to capture the Silver Surfer and Spider-Man and have them help him. He wanted the two to power his weapons. The two heroes escaped and they left Annihilus and Psycho-Man fighting for the Microverse. Annihilus's invasion was repelled.

Kidnapping of Rick and Franklin

Doctor Doom stole Annihilus's rod so he could steal Galactus's energy. Annihilus captured Rick Jones and would only release him if he got his rod back. The Fantastic Four managed to retake the rod and they returned it to Annihilus and Annihilus released Jones. Annihilus later fought Janus the Nega-Man and won. Since Annihilus won, he made Janus lead him to Earth, but Janus expolded where matter meets anti-matter. Annihilus almost crossed over to earth with Rick Jones, but the Avengers were there to stop him. The Vison tricked Annihilus to fall back into the portal to the Negitive Zone. Annihilus sensed Franklin Richard's power and abducted him. Annihilus amplified Franklin's mind causing it to go out of control. The Fantastic Four came and defeated Annihilus, but Reed Richards had to temporarily shut down Franklin's mind (so Earth's solar system would be protected).

Annihilus's History will be completed later

Annihilation

Annihilus has become aware that the Positive Zone universe is starting to over take the Negative Zone. With is army, the Annihilation Wave, Annihilus has travelled to the Positive Zone and began a purge of all life that his wave has come upon. He sent out seekers to capture the Heralds of Galactus. He made a deal with Thanos that saw the capture of Galactus himself possible. The Annihilation Wave has destroyed countless worlds.

Powers

Annihilus is a highly advanced insectoid being with strong chitinous armour, and super strength. His intellect is slightly above human average, though his strategic intelligence is a bit higher. Annihilus is able to fly with his own wings, even in the vacuum of space. He possesses a Cosmic Control Rod which allows him to manipulate cosmic energy and retards the aging process. He has a vast army of soldiers and ships known as the Annihilation Wave which are controlled through a hive mind.

When he gets killed he produces a clone of himself that retains all memories.
