Blastaar (Earth-21399)

Early Life
Blastaar was a resident of Baluur, a planet in the Negative Zone ravaged by war between various factions over scare resources. A mighty warrior and the son of a military commander, Blastaar gained his superhuman abilities during a battle with a rival faction over a supposed new resource. Finding himself trapped inside a cave, surrounded by his enemies, Blastaar discovered a mysterious blue rod hiding beneath the rubble, and blasted it with his plasma rifle out of sheer desperation. This somehow triggered a reaction that exposed Blastaar to the rod's energies, granting him the ability to project explosive shockwaves from his hands.

With his newfound power, Blastaar conquered Baluur and became a military dictator, nicknamed “the Living Bomb” by the people of Baluur. After consolidating power, Blastaar ejected the rod into a nearby wormhole to ensure no one else would challenge his rule.

The Annihilation Wave
With his wife and son by his side, Blastaar lived contentedly... at least, until the dreaded Annihilation Wave descended upon Baluur.

During the resultant sacking of the capital city, Blastaar's wife and son were brutally murdered by the madman known as Annihilus. Blastaar was so enraged that he destroyed a whole squadron of the Annihilation Wave as it descended on the research facility. Then, Blastaar challenged Annihilus himself to single combat. Annihilus refused, citing his belief that the universe has no use for honor, and ramped up his attacks.

Personality
Blastaar is motivated by two things: vengeance against Annihilus for killing his wife and son, and a genuine desire to protect his people, partly because of his own failure to protect his family. However, he approaches most situations from the perspective of a ruthless military commander, being concerned with victory above all else. Any alliances he makes are alliances of convenience, and they are usually temporary.
