Blastaar was the leader of Baluur, a planet in the Negative Zone. He was not liked by his people and after he was overthrown he shot off of the planet. He then drifted, unconscious through the Negative Zone. He was awakened when Triton entered the Negative zone to save Mr. Fantastic, and he followed them through their portal back to the Baxter Building. He joined with Sandman and tried to take over the world but was stopped by the Fantastic Four and Crystal of the Inhumans. Blastaar was sent back to the Negative Zone where he regained control of Baluur and has tried to take over the rest of the Negative Zone. Annihilus is the only being in the Negative Zone who is strong enough to oppose him and Annihilus also wants to take over. Blastaar has been back to this universe to help in the battle against the Annihilation Wave. He has also been back to help the Kree battle the Phalanx.
