Superman possesses few vulnerabilities in the world of DC Comics, with Kryptonite standing out as a well-known weakness originating from his home planet, Krypton. This mineral weakens Superman significantly due to its radioactive properties, leading to the creation of multiple variations over time.

Throughout the extensive history of DC Comics, a plethora of surprising Kryptonite variations have emerged, each with distinct effects that have influenced Superman's adventures. These variations have not only introduced new powers but have also led to the combination of different types of Kryptonite, resulting in hybrid effects with multiple consequences.

16 Green Kryptonite

Weakens Kryptonians, Draining Them Of Their Powers

• First Appearance: Action Comics #161 (1951)

Among the most prevalent forms, Green Kryptonite is widely recognized for its ability to weaken Kryptonians, stripping them of their strength and abilities, ultimately leading to their demise. This variant has been frequently wielded by adversaries like Lex Luthor and Batman in their confrontations with Superman.

The radiation emitted by Krypton is the source of Kryptonians' superpowers, making them vulnerable to the enfeebling effects of Green Kryptonite, a resource often kept in reserve by characters such as Batman for use against Superman if necessary.

15 Red Kryptonite

Occasional Mutations & Mood Swings

• First Appearance: Adventure Comics #255 (1958)

Introduced after the standard green variant, Red Kryptonite exhibits peculiar and diverse effects on Kryptonians, including mood swings and sporadic mutations. Apart from weakening Kryptonians, this variant is notorious for causing unexpected behavioral changes, making it a unique storytelling element.

Initially known for inducing mood alterations, Red Kryptonite has also demonstrated the ability to trigger physical mutations in Kryptonians, adding an intriguing layer of complexity to the consequences it inflicts.

14 Gold Kryptonite

Can Remove The Powers Of A Kryptonian, Potentially Forever

• First Appearance: Adventure Comics #299 (1962)

Originally a formidable threat to Kryptonians, Gold Kryptonite had the ability to permanently nullify their solar-based powers, rendering them ordinary. However, subsequent alterations in its portrayal post-crisis have limited its effects to a temporary deprivation of powers.

Had it retained its original potency, Gold Kryptonite would have posed a perpetual danger to Superman and his kind, becoming a coveted weapon for adversaries seeking to neutralize the Man of Steel permanently.
