The Anti-Kryptonite suits were a series of protective suits designed and created by Winn Schott, to protect Clark Kent as Superman and Kara Danvers as Supergirl respectively, from the radiation effects of Green Kryptonite.
Astra and Non's army employed Anti-Kryptonite suits (really, small clip on electronic devices) that blocked the effect of green kryptonite radiation, but did not block bladed weapons forged with kryptonite alloys.
- Green Kryptonite resistance: The suits are used to defend Superman and Supergirl respectively from the Metallos and their Green Kryptonite.
- Clark Kent/Superman (formerly)
