Kryptonite is a radioactive mineral that made up most of the planet Krypton's structure, including its core.There are multiple forms of Kryptonite that vary in color and effect on Kryptonians.

Types of KryptoniteEdit

  • Green:Green Kryptonite is the most common form and makes kryptonian's feel dizzy,nauses,in pain and in long enough exposure can render them unconsious and possibly kill them.This can be avioded with lead.When being exposed to green K the kryptonian's invulnerability is by passed.
  • Red:Red Kryptonite is a bit rarer than green but can still be found.Red Kryptonite strips a kryptonian of his inhibitons and social consience making their deepest desire's come to the surface,so they act on their emotions.Red kryptonite basically brings out their "Primal Instincts".In the TV series Clark has a split personality while under Red K,Kal short for his birth name Kal-El.According to Clark Kal "does things [Clark] doesn't want to do".
