Meteor infection is the process of acquiring metahuman powers due to green kryptonite exposure.

Meteor-infected individuals who acquired their powers from a meteor shower, especially if they use their abilities to threaten, hurt or kill other people, are often referred to as "meteor freaks." Chloe Sullivan and Lana Lang, however, have started using the terms "meteor-challenged" or "meteor-infected" instead. (Cure) After Jimmy Olsen learned about Chloe's meteor power, he also stopped using the phrase "meteor freaks." (Gemini)

Powers and Abilities

Two factors greatly increase the odds of meteor infection:

  • The specific type of exposure: ingestion, inhalation, envenomation, sting, viral/bacterial/fungal infection, injection, genetic manipulation, etc.
  • The amount of exposure.
  • A catalyst such as electricity, magnetism, intense heat, or even death itself.


Meteor infection can in many cases cause psychosis, for which there is no known cure other than removing the factors which cause the meteor power; Dr. Curtis Knox developed such a cure.[1] It can also cause the "jitters," resulting in uncontrollable tremors, which are generally associated with a terminal level of meteor exposure.

Type of Exposure

Meteor infection is most likely to occur if the kryptonite enters the body. This can include several means:




  • Sasha Woodman was stung by bees that were exposed to kryptonite, and was subsequently able to control bees. (Drone)


  • Greg Arkin was bitten by kryptonite-exposed insects, giving him the powers of insects. (Metamorphosis)
  • Lana Lang drank the blood of Buffy Sanders, receiving Vampiric powers. She also gained additional powers after biting Clark Kent. Sanders also received her powers from the bite of a Kryptonite-infected rabid Vampire bat. (Thirst)

Wound & Subsequent Catalyst

  • When Earl Jenkins was exposed to a green mist when an explosion in the fertilizer plant occurred, the kryptonite also penetrated his skin. (Jitters)
  • Tyler Randall had a piece of kryptonite directly embedded in his wrist and then died but was saved with life saving drugs and medical procedures. (Reaper)
  • Seth Nelson was hit in the head with a snow globe containing meteor rock, putting flecks of the kryptonite directly into his head and later exposed to an MRI. (Magnetic)

Medical Treatment



  • Andrea Rojas got a heart transplant from a metahuman. (Vengeance)
  • Curtis Knox attempted to transplant kryptonite-rich organs into his wife's body, to give her immortality. (Cure)


Genetic Manipulation




Certain catalysts greatly increase the chance of a successful meteor infection:


  • Harry Volk fell into a meteor-filled pond and his motorized wheelchair shorted out. (Hourglass)
  • Eric Summers was struck by lightning while holding kryptonite. (Leech)
  • Lana was also struck by lightning while near kryptonite. (Wrath)






  • The Isis Foundation is a non-profit organization dedicated to helping the meteor-infected. It was founded by Lana and was later run by Chloe until late 2009. Its current status is unknown.
