Hardening


 * Not to be confused with Harden.

Hardening is a Quirk used by Eijiro Kirishima.

Description
Eijiro's Quirk gives him the power to harden any part of his body. The ability not only protects him from physical attacks, but also from heat and shock waves. This Quirk is strong enough to protect Eijiro from several tons of metal falling on him as well as several explosions caused by Katsuki Bakugo through an extended amount of time. It can be used as both the strongest defense and the strongest attack.

The drawback to the Quirk is that there is a limit to how much damage the hardened skin can withstand, causing the hardening to slowly dissipate.

Named Techniques

 * Red Counter: While hardened, Eijiro endures a close-range attack with his skin, and then counters with a straight punch.
 * Red Riot Unbreakable: Eijiro reaches his maximum hardening level by turning his entire body extremely hard and rugged, leaving him with a monstrous appearance and practically invulnerable to most forms of attack. This form can only be maintained for around 30 to 40 seconds.
 * Red Gauntlet: While using Red Riot Unbreakable, Eijiro rushes towards the enemy and delivers a single strong punch against them.

Trivia

 * This Quirk is very similar to Steel, and the two appear to be roughly equal in terms of power and effectiveness.
 * This Quirk, in terms of function, is the inverse of Harden, which consists of hardening foreign objects instead of one's own body.
