Dr. Steven Hamilton, also known as The Meteor Freak, is a supporting antagonist from the First and Second seasons of Smallville appearing in 4 episodes of the series.
He is a mineralogist with a deep obsession for the meteor rocks that fell upon Smallville in 1989 and has dedicated himself to studying their unusual properties and suspected that aliens came to Earth.
He was portrayed by Joe Morton.
Hamilton was a former professor at Metropolis University who lost his tenure after pursuing inappropriate relations with a student. Following the 1989 meteor shower, he lived as a recluse outside of Smallville, Kansas and sold fake meteor rocks to tourists while conducting haphazard research on real ones in his shack.
Lex Luthor would eventually take an interest in his work and offered to fund his research as a mineralogist but Dr. Hamilton refused his offer. Lex again went to visit Hamilton and gave him a check for $100,000, insisting that he continue his research regarding the link between meteors and human health, offering funding and proper facilities to carry out his research. Dr. Hamilton believed that the meteor rocks turn people into corrupted versions of themselves and that the whole town has changed.
Doctor Hamilton used green meteor rock radiation on dormant plant seeds to revive a once extinct flower known as the Nicodemus flower. It was believed that flower released spores that would remove one's inhibitions, releasing their innermost urges. However, the altered spores proved to be extremely harmful, and several individuals were affected and made ill including Jonathan Kent, Pete Ross and Lana Lang. Hamilton succeeded in finding a cure for this condition.
Dr. Hamilton led the excavation team at Miller's Field and found something interesting. Another component to the mystery of the meteors: an octagonal-shaped disk made from an extraterrestrial alloy. He gave the disk to Lex but the disk would later be stolen by Roger Nixon.
Due to his constant exposure to meteor rock, Dr. Hamilton started having constant seizures. Hamilton arrived at the Luthor Mansion, twitching uncontrollably and complains about the problems he is having doing his research. Seeming even more unstable, Dr. Hamilton leaves and caused a traffic accident in which a van goes off the road and overturns into a cornfield. Pete Ross comes upon the scene just as Dr. Hamilton speeds away and discovers a spaceship in the field.
Later, Dr. Hamilton heard about a man who claims to have seen a spaceship in a cornfield -- Ray Wallace, the same man he ran off the road. Hamilton knows the ship is no longer in the cornfield and demands answers from Ray. Ray tells him that Pete Ross pulled him out but when he recognizes Dr. Hamilton, he kills Ray with a lethal dose of morphine.
Dr. Hamilton discovered Clark Kent's spacecraft after Ray blabbed about it. The ship was recovered by Pete Ross, but Hamilton stole it from Pete's garage. In his barn, Dr. Hamilton is frantically trying to open the spaceship when he discovers a space which reminds him of a piece he found during the excavation of Miller's Field. He goes to the mansion to retrieve the disc from Lex, but Lex no longer has it.
On his way out, Hamilton runs into Lionel Luthor in the corridor and persuades him consider funding his research. Guiding Lionel's hand around the ship, Dr. Hamilton tells him about the missing piece. Lionel promises that when Hamilton finds it, he might get his funding.
