Powers and AbilitiesEdit

Effect on Kryptonians

Blue kryptonite suppresses Kryptonians' power and abilities under a yellow sun, making them essentially human and without any superpowers. ^{[citation needed]}

When part of a bullet, blue kryptonite can also temporarily suppress a Kryptonian's invulnerability long enough to leave a tracking code on his or her skin. (Shield)

As a result, Kryptonians under the influence of blue kryptonite are immune to the crippling effects of green kryptonite radiation. ^{[citation needed]}

Despite the fact that this stone removes their abilities, Clark has proven on numerous occasions to have retained some body resistance while under its influence. (Persona, Lazarus, and Harvest)

Effect on Bizarro

Blue kryptonite has the opposite effect on Bizarro; reflecting the inverted nature of his body's ability to process energy, rather than removing his powers, it overloads his body with power, causing him to explode, compared to attempting to power a lightbulb with a nuclear reactor.

Effect on humans and environments

It also purifies water and makes crops grow even in the harshest of environments and humans, by ingesting it, become perfectly healthy, giving off its radiation.

VulnerabilitiesEdit

The effects of the blue kryptonite are controlled by proximity, just like other types of kryptonite. Its powers will fade away if the Kryptonian is at a certain distance of it, or if it is stored inside of a lead box.

In the case of jewelry, it needs to be worn.

Unlike Gold kryptonite, the effects of blue kryptonite persist only while the person is exposed to it.

Also, blue kryptonite will not be effective under a red sun, which Alia used it to gave herself power under the yellow sun (because Kryptonian DNA which has been radiated with blue kryptonite will not have powers under the yellow sun except that Kryptonian have the blue kryptonite that would switch the results back).

Early HistoryEdit

A small town outside of Metropolis was hit with a few meters from the first meteor shower and had blue kryptonite in it. For 20 years, the town people used it to make their water fresher and make their crops grow.

Season SevenEdit

After activating the blue crystal in the Fortress console, it created an exact duplicate of Lara-El and Zor-El.

Lara gave Clark his father's victory ring, which had blue kryptonite. Unknown to Clark, once he put it on it stripped him of his powers, part of a plan orchestrated by Zor-El. Only by destroying the crystal did he manage to get rid of the ring, but he also unwillingly destroyed the clones of his mother and uncle in the process.

Another instance was when Clark asked Lionel (who was really Brainiac in disguise) for a way to stop Bizarro, and he suggested he use the blue kryptonite, as it would destroy Bizarro from an overload of power.

Lionel tells him to find Dax-Ur, using the Kryptonian shield he found and after meeting with Dax-Ur, who showed him a bracelet made ​​of blue kryptonite that he was wearing to live a normal life, Clark obtained a piece of blue kryptonite and faced Bizarro. During their confrontation, Lana used the kryptonite to destroy the last phantom.

Season NineEdit

A Kryptonian soldier time-traveled back from the future with Lois to assassinate Kal-El. Kal-El and the soldier later battled and she used the blue kryptonite to make them mortal-like so she could kill him with her sword, which she wouldn't have been able to if he had his powers.

It was also revealed that when Jor-El was forced to create the Orb and include the DNA of Kryptonian soldiers, he radiated the Orb with blue kryptonite radiation, making all of the clones powerless so that they could not rule earth under a yellow sun.

Zod made a blue kryptonite knife in order to prevent himself from going to a new world with the rest of the Kandorians. After a brutal fight between Clark and him, Clark decided to stab himself with the knife and fall off the tall building they were fighting on. Thus keeping distance between the blue kryptonite and Zod. Afterwards Zod's powers were returned and he was sent to the new world to the rest of the kryptonian clones.

Season TenEdit

After sending the Kandorians away, Clark still fell to his death with the blue kryptonite dagger in his abdomen, but Lois saw him fall and tried to revive him but was unsuccessful then noticed the dagger and pulled it out of Clark's body and threw it a great distance away from him. The sun rose and Clark healed.

When Clark came near any of the townspeople affected by blue kryptonite (or their water), he would lose his power. Clark was burned by blue kryptonite infused fire trying to save Lois.

Clark was marked with a blue kryptonite tattoo by Deadshot's bullet. Later, Emil Hamilton removed the tattoo.

Alternate RealitiesEdit

Season Ten (Earth-2);

In a parallel universe where Clark was raised as the adopted son of Lionel Luthor, he and Lionel had sword practice in which the swords were tipped with blue kryptonite.

In the ComicsEdit

Blue kryptonite is the Bizarro analogue to green kryptonite. Using Bizarro logic, this, in general, hurts Bizarros while having beneficial effects on ordinary Kryptonians. Pre-Crisis, blue kryptonite is the result of using Professor Potter's "duplicator ray" on some green kryptonite. Here, blue kryptonite affects Bizarros like green kryptonite affects Kryptonians. Blue Kryptonite radiation is not blocked by normal lead, but by imperfectly duplicated lead. Bizarro World, a sentient planet, had animated Blue Kryptonite golems underground that surfaced and attacked the Super-Powered Bizarros while the delighted non-powered bizarros cheered them on. When Jimmy Olsen had his mind turned to that of a Bizarro, Exposure to Blue Kryptonite radiation turned his mind back to normal. In an episode of Super Friends, blue kryptonite heals Superman from the effects of red kryptonite. Post-Crisis, its origin is unknown. Here, blue kryptonite makes Bizarros become polite, goodhearted, coherent, and intelligent. It also causes physical pain much like green kryptonite affects Superman. In the Direct-To-DVD movie, Justice League: Crisis on Two Earths, Blue Kryptonite harms Ultraman (Superman's criminal counterpart in an alternate reality) in the same manner that Green Kryptonite harms Superman.

Blue kryptonite has also been used in Superman video games as a life restorative due to its "Bizarro" nature. ^{[citation needed]}
