## History

### Pre-Crisis

Blue Kryptonite was created using the Duplicator Ray on a piece of Green Kryptonite which Superman used to halt an army of advancing Bizarros. Blue kryptonite only affected Bizarros and was harmless to humans and Kryptonians.

### Post-Crisis

Blue kryptonite was the opposite to the more common green variety and made Kryptonian-based Bizarros highly intelligent, a process that scared them.

### Post-Infinite Crisis

Blue kryptonite caused Bizarro pain much like green kryptonite crippling Superman.

### Prime Earth

An enemy from the Anti-Superman Army dubbed the Blue K-Man stated that his kryptonite radiation wavelength was cancerous to the soul. Xa-Du, the Phantom King, recoiled out of fear while in the Kryptonite Man's presence because he was an ethereal being from the Phantom Zone, and blue kryptonite radiation caused spiritual death.

Blue kryptonite suppressed Clark's powers, at least for a time. During the effects, Clark was also immune to the symptoms of green kryptonite. The blue kryptonite was forged into Jor-El's victory ring which was presented to him when he first became a member of the Kryptonian Science Council. Clark's resurrected mother, Lara Lor-Van, gave him the victory ring while explaining that it was a Kryptonian tradition to pass the victory ring onto the firstborn son when he came of age. Unknown to her, the ring had been a trap set by Zor-El to strip Clark of his powers. Blue kryptonite was used to overload and kill Bizarro.

### Super Friends
