Star Thief also convinced Adam Warlock he could grow larger than the entire planet Earth and terrorized Halfworld (Rocket Raccon's homeworld) as a giant red energy being.
Barry Bauman was born with a nerve disorder which left him with normal intelligence, but no sense of sight, hearing, smell, taste, or touch. Barry's father was chairman of the board of the hospital, so the received 24-hour care every day of his life. Without outside stimulation/disturbance, he learned to fully access his entire mind (as opposed to the 10% accessed by normal humans). This apparently granted him thousands of time more mental power than others. After exploring his own mind, he eventually scanned outside of his body and first encountered his nurse, Tom Vocson. This was when he learned that he was different from others. He learned to take mental control of Vocson, and experience life through his five senses. He used Vocson to race through endless volumes of all types of books to learn the basis of all human knowledge.
Bauman soon developed telekinesis and used it to affect objects around him, initially in the form of pranks, and later causing massive accidents and even earthquakes. Feeling that mankind could have cured his disorder with a little effort, and resentful over his condition, he sought revenge on all of humanity. Casting his mind out into space, he first thought to send a massive asteroid to crash into Earth, but then came upon an idea where he could watch humankind suffer and fear their extinction. He began to cast the stars within Earth's sight into a pocket dimension created by his mind. He planned to slowly wipe out all stars in sight, then abandon his corporal form and cast his mind out into space after destroying Earth's sun as well.
Baumann the Star Thief
The man known as Adam Warlock, at that time in the Andromeda Galaxy, discovered the stars disappearing and investigated. Using his soul gem, he probed the mind of Barry and learned of his plot. Bauman then followed the probe back to Warlock, explained his origins and plans, and challenged him to stop him. Realizing he could instantly disintegrate Warlock, and seeking a challenge for himself, Barry, now calling himself the Star Thief, vowed to only use his abilities to manipulate physical objects against Warlock until he reached Earth.
Warlock survived his challenges and raced back to Earth, even apparently braving a black hole in the process. However, when he reached Earth, he now found himself dwarfing the entire planet. Star Thief explained this as being due to the different rates of expansion of the universe, but it was later learned to be a trick by him. At any rate, with Warlock now having reached Earth, Barry was free of his vow to limit his attacks and prepared to destroy him. However, Barry had become so intrigued with battling Warlock, that he had relaxed his control over his nurse, Tom Vocson. Vocson, fully aware of Barry's actions, stole a gun and put a bullet through Barry's head, instantly killing him. Barry was apparently siphoned into the Soul Gem.
(Annihilators#3/2 (fb)) - Although Bauman's body had died, his alpha-class psychic mind jumped from host to host. Eventually he was brought to the Halfworld Asylum, his admission supervised by Rocket Raccoon. Despite all therapy, Bauman disrupted the inmates, even taking over Psychology Head, Dr. Dyvyne. To stop Bauman, Raccoon turned the bio-organic Halfworld into a living prison, with Raccoon as the living key, so he left Halfworld. Meanwhile, Bauman took over the second-in-command, Judson Jakes, for a while and devised a plan that would bring Rocket Raccoon back to Halfworld so that he could escape. However, Bauman had managed to shunt his consciousness into the bio-facility of Halfworld.
(Annihilators#3/2) - Bauman appeared in a red energy form before Rocket Raccoon, Groot and various Halfworld staff, and announced he would soon be free.
(Annihilators#4/2) - Star-Thief had Rocket Raccoon, Groot and others incarcerated in an immersion environment while Bauman's energy form entered the cerebral core of a spaceship being readied for launch, but Raccoon was able to escape with the aid of Groot. Recognizing the Thanos-level threat of the reborn Star-Thief, Raccoon enlisted the aid of Blackjack O'Hare and they managed to destroy Bauman's means of escape. After viewing historical tapes of Bauman's life, Rocket Raccoon dressed as Vocson's dog, Mr. Binkey, to distract Bauman so that Halfword's security system could be rebooted. The plan succeeded and Bauman was incarcerated in an happy enviroputic world that kept him sedated.
