Blue Kryptonite

Blue Kryptonite is a type of kryptonite featured in the Superman comic books, the Supergirl television series and The Smallville TV series.
On Smallville, blue kryptonite renders Kryptonians somewhat powerless. Blue kryptonite was used to overload and kill Bizarro. 
On Arrow's Supergirl, it weakens Bizarro.It was the opposite of regular kryptonite with a reversed ionic charge.
Blue kryptonite was synthesized by the DEO in order to take down Bizarro after green kryptonite proved inadequate for the task. Jor-El used it in his power ring and injected the cloned Kandorians in the Orb with blue kryptonite so they would only have access to their powers under a red sun instead of a yellow one.
