Xerox

Xerox (ゼロックス Zerokkusu) is the Quirk used by Kaneki(Nemesis)
Description
The Xerox Quirk take shape as black flame-like creations, these can summoned from Kaneki's hands and thrown, shot, etc. The quirk is very powerful, as once it hits it's target, if the flames grow enough, they will erase the target's quirk for a few seconds to a few minutes, this all depends on how powerful the flames grow. These flames can be used for attack or defense, as Kaneki can use the flames to attack his enemies, and also use Xerox on himself, to defend himself.
Weaknesses
One of Xerox's biggest weaknesses, is that the quirk itself isn't very powerful without extra quirks or time to ignite and grow. This quirk also doesn't have an very effective range, as the flames grow weaker the farther, you go from Kaneki. This quirk is made more useful with Kaneki's other quirks.
