Question: Is Jor-El also weak to kryptonite?

Kryptonite



Kryptonite is a material that appears primarily in Superman stories. In its most well-known form, it is a green, crystalline material that emits a peculiar radiation that weakens and sickens Superman, but is generally harmless to humans when exposed to it in short term. However, when it gets into their bloodstream it can poison them. There are other varieties of kryptonite such as red and gold kryptonite which have different but still generally negative effects on Superman. Due to Superman's popularity kryptonite has become a byword for an extraordinary weakness, synonymous with "Achilles' heel".[1]
Origin

An unpublished 1940 story titled "The K-Metal from Krypton", written by Superman creator Jerry Siegel, featured a prototype of kryptonite. It was a mineral from the planet Krypton that drained Superman of his strength while giving superhuman powers to mortals. This story was rejected because in it Superman reveals his identity to Lois.[2]
The mineral known as kryptonite was introduced in the radio serial The Adventures of Superman, in the story "The Meteor from Krypton", broadcast in June 1943.[3] An apocryphal story claims that kryptonite was introduced to give Superman's voice actor, Bud Collyer, the possibility to take a vacation at a time when the radio serial was performed live. In an episode where Collyer would not be present to perform, Superman would be incapacitated by kryptonite, and a substitute voice actor would make groaning sounds. This tale was recounted by Julius Schwartz in his memoir.[4] However, the historian Michael J. Hayde disputes this: in "The Meteor From Krypton", Superman is never exposed to kryptonite. If kryptonite allowed Collyer to take vacations, that was a fringe benefit discovered later. More likely, kryptonite was introduced as a plot device for Superman to discover his origin.[5]
In the radio serial, Krypton was located in the same solar system as Earth, in the same orbit, but on the opposite side of the Sun.  This provided an easy explanation for how kryptonite found its way to Earth.
Kryptonite was incorporated into the comic mythos with Superman #61 (November 1949).[6] Editor Dorothy Woolfolk stated in an interview with Florida Today in August 1993, that she "felt Superman's invulnerability was boring."[7]
Forms: colors and effects 
Various forms of the fictional material have been created over the years in Superman publications.


Other varieties of the material have appeared, but have been revealed to be hoaxes, such as "Yellow" (Action Comics #277 (June 1961)), "Kryptonite Plus" (Superman's Pal, Jimmy Olsen #126 (Jan. 1970)) and "Blood" (52 #13 (Aug. 2006)).

In other media

Television
Live-action
The Adventures of Superman (1952-1958) featured kryptonite in the episodes "Panic in the Sky", "The Defeat of Superman", "Superman Week", "The Deadly Rock", "The Magic Secret", "The Gentle Monster" and "All That Glitters".
Superboy (1988-1992) featured green kryptonite in the episodes: "Kryptonite Kills" and "Metallo", "Bride of Bizarro", "Kryptonite Kid", and "Obituary for a Super-Hero". The red variety was featured in the episode "Super Menace". A Bizarro White variant was featured in the episode "The Battle With Bizarro", which heals the title character.
Lois & Clark: The New Adventures of Superman (1993-1997) featured green kryptonite in the episodes "The Green, Green Glow of Home", "Barbarians at the Planet", "The House of Luthor", "Metallo", "Top Copy" and "Battleground Earth". The red variety was featured in the episodes "Individual Responsibility", "Ultrawoman" and "Lethal Weapon".
Smallville (2001-2011) featured kryptonite on a regular basis. A large quantity of the green variety descends to Earth in a meteor shower, arriving in the town of Smallville, Kansas with the spaceship containing the infant Kal-El. The material is colloquially referred to by Smallville residents as "meteor rock", but is eventually called "kryptonite" by Clark Kent once he discovers his origins in season two episode "Rosetta" (in real life, the area near Brenham, Kansas is known as the site of a major meteorite strike between 10,000 and 20,000 years ago).[13] Aside from being harmful to Clark Kent, the mineral produces bizarre changes in flora and fauna. It also occasionally bestows metahuman abilities on humans depending on the circumstances of their exposure to it, such as a girl treated for a rare bone disease acquiring shapeshifting powers. These people are commonly known by the inhabitants of Smallville as "Meteor Freaks". The green variety of the mineral appears in several episodes every season, although other varieties appear, including: red in "Red" (2002), "Exodus", "Exile", "Phoenix" (2003), "Unsafe" (2005), "Crimson" (2007) and "Upgrade" (2010); black, formed when superheating green kryptonite in "Crusade" (2004) and "Doomsday" (2009); silver in "Splinter" (2005); blue in "Blue" (2007), "Persona" (2008), "Kandor" (2009), "Salvation" (2010) and  "Harvest" (2011); as a gem in "Persuasion" (2010) and gold in "Prophecy" and "Finale" (2011). Smallville was the first appearance of a black kryptonite that would split a person into their good and evil halves, before later being brought into the comic canon in Supergirl (vol. 5) #2 (Oct. 2005).
Supergirl (2015–present) featured green kryptonite in the episodes: "Pilot", "Stronger Together", "Hostile Takeover", "For the Girl Who Has Everything", and "Distant Sun". In the second part of Arrowverse's 2017 crossover "Crisis on Earth-X," reveals that Green Arrow of Earth-1 somehow obtains samples of green kryptonite, and uses them to construct kryptonite arrows as deterrents against rogue Kryptonians such as Overgirl (Supergirl's parallel universe counterpart from Krypton-X) and Superman imposter John Deegan (on 2018 crossover "Elseworlds"). DEO manages to synthesize and create blue kryptonite which is featured in the episode "Bizarro". The red kryptonite is featured in the episode "Falling" as a failed attempt to recreate green kryptonite by Maxwell Lord. Silver kryptonite is featured in the episode "Nevertheless, She Persisted". In season 3, the black kryptonite is pivotal to its arc, first appearing in the episode "The Fanatical", in which it is being referred to as Harun-El by Kryptonians. The Worldkiller Coven from Krypton, headed by dark priestess Selena, schemes to use the Harun-El to terraform Earth into a Krypton-like planet for Kryptonians to inhabit. The protagonists uses the Harun-El to split the Worldkiller Coven's servant, Reign, from her human alter-ego Samantha Arias. By the end of the season finale, it is implied that Supergirl's being is also divided after her exposure to it during her final battle with Reign.

Films
In Superman (1978) Lex Luthor (Gene Hackman) deduces that a meteorite found in Addis Ababa is actually a radioactive piece of the exploded planet Krypton. Luthor uses the mineral to weaken Superman (Christopher Reeve), who is saved by Luthor's lover Eve Teschmacher (Valerie Perrine).
In Superman III (1983) billionaire Ross Webster (Robert Vaughn) orders the creation of synthetic kryptonite. Computer programmer Gus Gorman (Richard Pryor) uses tar to compensate for an unknown component of kryptonite, causing the newly created mineral to eventually turn Superman evil and split the hero into two beings. Gorman's "supercomputer" later fights Superman and uses a kryptonite ray.
In Superman Returns (2006) Lex Luthor (Kevin Spacey) steals the Addis Ababa L9 Pallasite Meteorite and uses kryptonite to create a new Kryptonian landmass and a dagger for use against Superman. The film describes kryptonite's formula as "sodium lithium boron silicate hydroxide with fluorine". A year after the film was released, a substance with a similar formula was discovered, jadarite, a coincidence which led to media attention.[14][15][16][17] The new mineral, unlike the fictional material in the movie, does not contain fluorine and does not glow green.[14]
In Justice League: Crisis on Two Earths (2010) an alternate universe version of Lex Luthor uses blue kryptonite against the villain Ultraman.
In Justice League: Doom (2012), the villain Metallo wounds Superman with a kryptonite bullet, but he is saved by the JLA.
In Batman v Superman: Dawn of Justice (2016) kryptonite is discovered by men working for Lex Luthor (Jesse Eisenberg) at the bottom of the Indian Ocean and experimented with by Luthor, who learns of its harmful effect on Kryptonians when the corpse of General Zod is exposed to it. The kryptonite is then stolen from Luthor by Batman (Ben Affleck), who uses it to create kryptonite gas pellets and a kryptonite-tipped spear, both of which he later uses in battle with Superman (Henry Cavill). Doomsday is also shown to be weakened by kryptonite, allowing Superman to use the spear to kill him in the film's climax.[18]
