The High was an extra dimensional being sent to 1910 Earth by a space ship. After being raise by the humans Mr. and Mrs. Cumbleland, he became a superhero and was active in the 1930s. He was a member of the Big Three (Maximum Man and Mister Majestic being the others) and friend of Jenny Sparks. However after three years, he became frustrated, which led him to going into self-exile. Living on top of the Rocky Mountains, he formed the Changers, a team of him and his most-trusted allies.
The Changers decided to change a world with self-government and without desires. However, they were opposed by Henry Bendix (who turned out to be insane) and Stormwatch (whom Jenny was a member of). The High attacked the UN and symbolically destroyed the flags of the various nations. Spark tried to convince the High his plan was a stupid idea. However, Bendix fired acid bombs (via Hammerstrike Deep Sanction Missile) thus killing all of the Changers except the High. He attacked the Skywatch base, but the force field seemly killed him.
The High later appeared Number of The Beast. He somehow survived and was cloned. His mind and the minds of 666 other heroes were sent into a virtual reality world. Two heroes escape and attacked their captors. However, the High clones caused massive chaos and destruction. Various hero such as Wildcats, Authority and Mr. Majestic fought the clones. The High was freed and killed the clones, but was unable to prevent all the destruction and death caused by the clones.
He has the basic flying brick powers: flight, super strength and invulnerability. He also had super speed, enhanced sight and "plasma vision". He slowly ages and doesn't need food or drink. He can survive in space.
