As a young boy, Thom Kallor was taking a spin in the family spacemobile and came too close to a comet. The spacemobile went through the gasses in the comets tail, and the radiation changed Thom. His return to home resulted in the spacemobile crashing and Thom flying from the wreck without a scratch. Along with his parents, Thom started exploring his new abilities, and he decided to use his new powers to fight crime. He donned a special costume and took the name Star Boy [Adventure Comics #282].
On a visit to Earth he met the Legion of Super-Heroes and joined them [Adventure Comics #282].
When Nura Nal, Dream Girl, first joined the Legion, Thom Kallor was attracted to her [Adventure Comics #317]. The attraction he discovered was more than that and Dream Girl was also in love with him. The Naltorean Kenz Nuhor who also loved Nura set out to kill Star Boy to remove the competition but ended up being killed by Star Boy instead. The death of Nuhor resulted in a trial where Star Boy was expelled from the Legion of Super-Heroes as killing even in self defense was not allowed [Adventure Comics #342].
After leaving the Legion, he joined the Legion of Substitute Heroes along with Dream Girl [Adventure Comics #342].
At some point he ended up in the present on Earth-22, and following the second Crisis he was transferred to Earth-1, where he ended up in the Justice Society.
Skills & abilities:
Thom has the ability to increase the mass of an object, even to the extent of simulating gravity of large worlds like Krypton. The mass is taken from the stars and is only temporary. For a time after he was exposed to the gasses from the comet, he had powers similar to Superboy like invulnerability, super-strength, super-speed, flight, and super-senses, though his x-ray vision was stopped by copper instead of lead, and he had electric vision.
Star Boy completed the Legion's personal combat training but is only a mediocre fighter in hand-to-hand combat.
