Star-Master, a superhero created by an anonymous author, first appeared in "Star-Master #1," a comic that was distributed online (the website has been removed since). When the website was still up, the creator wrote that Star-Master "got his abilities by reading a strange book he found." This was a cursed book that had fallen from space.
His powers are: the ability to see through solid objects like rooftops and walls, the ability to manipulate energy into blasts, flying, and immunity to damage caused by UV radiation. The Star-Master comic makes reference to the Zygor Clan, which is an evil clan that aims to take over Earth. A character named Tina is also mentioned, but there is no official statement regarding details about her connection to Star-Master.
"The character of Star-Master is available for use by anyone, with only one condition. This paragraph must be included in any publication involving the Star-Master, in order that others may use this property as they wish."
This hero, although he may be edited and adapted by anyone, only has one canon story, as stated in his official page (which, again, is now gone). Writers are still free to create their own version free of charge, as long as they include the above paragraph in their work.
Star-Master was confirmed by the creator to be a Catholic character of Irish and Scottish descent. His real name is Ralph Loveland. He listens to heavy metal, and his favorite color is blue. Not much else is known about him.
