Doctor Solar is a comic book superhero originally published by Creator/GoldKeyComics starting in 1962. A physicist whose name was actually "Solar", Philip Solar was trapped in a nuclear reactor by saboteurs. He survived and found that he gained enormous power and could turn into and produce energy. He was created by Paul S. Newman and Matt Murphy.

Solar held his own title from October, 1962 to April, 1969, for a total of 27 issues. The series was revived in the early [[TheEighties 1980s]], continuing the original numbering. Four issues appeared between April, 1981 and March, 1982. He had guest appearances in the Doctor Spektor series. But this was the extent of his use by the original publisher.

In the [[TheNineties 1990s]], Solar, followed by ''ComicBook/MagnusRobotFighter'' and later ''ComicBook/{{Turok}}'', was [[CanonInvasion licensed]] by Creator/ValiantComics. Under Creator/JimShooter, Solar became the central superhero of the Valiant universe. Doctor Philip Seleski had read the Gold Key comic books as a child and his thoughts affected the reactor to copy the comic book character's origin. He wielded godlike power, re-created the universe during his origin, and was responsible for several {{Crisis Crossover}}s.

In 2010, Shooter restarted this title, as well as ''Turok'' and ''Magnus, Robot Fighter'', for Creator/DarkHorseComics, who licensed the characters directly from Gold Key using stories based on Gold Key elements (for instance, he's named Phil Solar again). The series quickly ended after a combination of unpopular art and ScheduleSlip.

Doctor Solar (along with [[Creator/GoldKeyComics Magnus, Turok, and Doctor Spektor)]] has recently been revived again by Creator/DynamiteComics.
!!Solar has examples of:
* ButtMonkey: Erica Pierce.
** [[spoiler: Erica ''Seleski'' to a degree as well, at least until she gets better control over her powers.]]
* CrossOverShip: [[ComicBook/{{Deathmate}} He had a fling with Void]] from ''ComicBook/WildCATS'' once. It didn't end so well.
* {{Expy}}: Of ComocBook/CaptainAtom, who debuted two years before Solar. Captain Atom, in turn, influenced Dr. Manhattan of ''ComicBook/{{Watchmen}}'' and, in some ways, Solar is like an Expy of him.
* AGodAmI: A recurring theme in the series.
* ILoveNuclearPower
* LegacyCharacter: [[spoiler:In the Dynamite Comics revival, Solar becomes this when Phil dies and his daughter takes up the mantle.]]
* LiteralSplitPersonality: For a while, during the Creator/ValiantComics origin.
* MeaningfulName: In the original and Dark Horse versions, his surname is actually Solar.
* NotWearingTights: For his first couple of appearances, he did not wear a costume and did not have a codename (he just did his heroics surreptitiously).
* PhlebotinumDuJour: Shooter's series overview invokes black holes, magnetic monopoles, strange matter, transhumanism and nanotechnology.
* PowerIncontinence: In his early appearances, Doc emitted low-level radiation ''all the time'', and thus owned a lot of lead-lined clothes, spent most of his time in his lead-lined lab, and had to break up with his girl.
* StevenUlyssesPerhero: It's a good thing he didn't get, say, [[AnIcePerson ice powers]].
** Averted in the Valiant and Dynamite versions of the characters, where his last name [[spoiler:(and that of his daughter Erica, the second Solar)]] is Seleski.
* SuperpowerLottery: Something later lampshaded in the Valiant reboot as Seleski comments on how ridiculously bad the writing was to have a man with absolute control over energy being dangerously radioactive.
* TelephoneTeleport: Doctor Solar is capable of travelling like this.
* WithGreatPowerComesGreatInsanity: Subverted in the Dark Horse era; Shooter has written that power doesn't corrupt, power ''magnifies'' and a good man with power would have more opportunity to do good.
