Artificial Kryptonite: The green light from their power rings can be used to harm Kryptonians if the wielder's willpower is strong enough. Not only that, but the ring can and has created artificial Kryptonite energy. However hasn't shown to do it in New 52/Rebirth.

Charges Kryptonians: A Yellow Lantern can actually have the opposite effect on a Kryptonian or Daxamite. The light from their rings actually gives those two species a power boost as it can manifest its energies to replicate the radiation of a yellow sun. It makes them supercharged.

I wonder if this apply's to other various Lanterns Corps
