Technique Mimicry

Technique Mimicry is, as the name implies, the ability to copy the techniques and/or skills of other people.

Overview
Users of this ability can replicate the techniques and/or skills of those whom they've fought against or witnessed in battle; this can have varying degrees of success, with some being able to mimic a technique perfectly whilst others can only produce lackluster copies.

The results of mimicking a skill can depend on a number of different factors, such as the potential of the copier or whether the original user performed the copied technique at its highest level.

Some individuals who've been shown to possess this ability are: Garou, Orochi and G5.

Garou is capable of memorizing an opponents movements in order to copy their fighting style after only seeing it once, such as when he copied Watchdog Man's fighting style to an unknown extent and utilized it against Genos during their battle or when he managed to replicate Bomb's Whirlwind Iron Cutting Fist after seeing it just once, albeit he could only perform a lesser variation of it at first. However, being a prodigy in martial arts and having overcome a near suicidal degree of training by thrashing entire dojos as well as hunting down heroes, Garou improved Bomb's fighting style to a level where he could use the Cross Fang Dragon Slayer Fist, alone when it usually requires two fighters in order to work. After receiving powers from "God", Garou's ability to replicate fighting styles has been enhanced to where he's capable of even duplicating S-Class Rank 1 hero, Blast's ability to create portals as well as manipulate gravity just by fighting the top hero briefly.

As for Orochi, who's a prodigy in a similar vein as Garou, he's demonstrated himself to be capable of perfectly copying the latter's Water Stream Rock Smashing Fist after only glancing it once during their fight and use just as well as the Hero Hunter.

G5 has also shown to have copied Atomic Samurai's signature technique, Atomic Slash, to a lesser extent. As a result, G5 lost his battle against the hero.
