Quirk Name: Cnidocytes

Type: Mutant

Range: Contact

User: Jack Kelly

Alias: Stinger (Sometimes simply 'Jellyfish' or simply 'Jelly')

Description: As the name suggests, this quirk causes the user's skin to be covered in cnidocytes or nettle cells, similar to other animals within the phylum of Cnidaria, such as jellyfish or sea anemones, granting him a protection mechanism which causes microscopic, needle-like threads called cnidocysts to release on contact, which may inject venom. Unlike these animals, however, Jack has a certain degree of control over his cnidocytes that allows him to manipulate whether he releases his cnidocysts on contact or not, as well as how much venom he injects, including none at all.

Jack's cells contain an extremely potent venom that is capable of completely paralyzing any muscle in a target's body through a numbing effect, including involuntary ones like the heart. While the speed at which the venom operates is varying depending on the target's heart rate and the area of envenomation, the fastest at which it can kill is approximately a single minute.

Through training and general development of his quirk, Jack may even willingly release his cnidocytes without contact, utilizing his cnidocysts' full length of 4-5 meters to attack at range. He can also use this for more practical means, like grabbing small objects or gripping onto surfaces in a manner similar to the setulae and setae of spiders and geckos, respectively.

Techniques:

Thread Grapple: By releasing cnidocysts through his palms and retracting them again, Jack may pull anything caught by them closer to him. In combat, this is usually used to prevent escape.

Weaknesses: While Jack's cnidocysts are extremely durable when it comes to their tensile strength, especially for their relative size, they are still easily cut through by blades or other cutting tools.

The length at which Jack's cnidocysts are released influences the speed at which his venom is injected. If too long, anything stabbed by them may dig them out before it can even reach them.
