''Trace'' is a South Korean webtoon (webcomic) series written and illustrated by manhwa artist Go Yeong-hun or known as his pen name, "Nasty Cat".

Thirty years ago, a mysterious species of creatures known as Troubles began a gradual invasion to conquer the Earth. However, entering the human world unleashes energy with an unexpected consequence: the creation of humans with mutant superpowers. Whether they gain their new abilities at birth or in the course of life, these rare humans are known by only one name--Traces. A Trouble always leaves behind a Trace.

One such Trace is Gangkwon. His birth as a Trace killed his father and terrified his mother to such an extent that she fled for her life. Now, he must live a double life to protect his adopted family. By day, he plays the role of school wimp, but by night he's a Trouble hunter. All goes well until one day, a Trouble appears in his very own classroom and threatens Taeun--his closest friend and family member.

Kim Yun-Seong is another Trace, who acquired his mutant abilities during his early 30s. Soon after the acquisition, his wife and daughter were taken away from him for experimental purposes. All goes well until he loses contact with his family. There is an attempt at his life. Yun-Seong reports this to the police and finds himself a wanted man. He eventually finds where his family is but can't go in because of the Traces guarding the building. After almost getting killed, another Trace finds him and offers a plan to get into the building.

%%please don't wiki word Trace
* AdultFear: This is unique among other X-man-esque spin-offs in the fact that it follows the journey of a middle aged business man as he develops mutant powers, rather than the usual gang of high school teenagers. Since this a CrapsackWorld he lives in, his wife and daughter are taken away by the government under the pretense of normal screening and testing, when really [[spoiler: they are used for human experimentation. The protagonist doesn't realize this until he breaks into the facility, where he is greeted by the sight of his wife's head floating in a vat.]] Talk about preying on a typical father's worst feelings of helplessness.
* AuthorAppeal: The artist said that he wanted to create the world of superheroes with a Korean identity.
* AngerBornOfWorry: Kwon Ghang Sa and Eun Tae Han, to each other.
* AnIcePerson: Sa Ghang Gwon
* BodyHorror
* CreepyChild: That mysterious kid with the bowl cut.
* CurtainsMatchTheWindow: Everywhere.
* CuteBruiser: Cha Mi-ri
* DefrostingIceQueen: Jang Mi to Morrienoah Jin, [[spoiler: which turns out to be a double subversion. Though Jang Mi still went through with the original plan.]]
* [[spoiler: DeadAllAlong: Kim Yun Seong family is explained to have been killed shortly before the attack that led him to suspect that something was going terribly wrong.]]
* EldritchAbomination: The Troubles, they're vaguely human in shape but have some form of body horror.

* {{Mutants}}: The Traces.
* MysteriousWatcher: That creepy kid with the bowl cut.
* OnlyKnownByTheirNickname: At some point most people forget that The Beggar's name is actually Kim Yun-seong. It doesn't help much when non-Korean readers have trouble getting Korean names.
* PersonalityPowers: There's a couple of examples, mostly however is the violent Cha Mi Ri's super strength.
* RagtagBunchOfMisfits: The Beggar Team, consisting of a beggar, some assassins, a gambler who cheats, a bank robber, and violent schoolgirl.
* RequiredSecondaryPowers: Traces tend to have MadeOfIron as a secondary power.
* {{Superhero}}es: The traces do resemble mutants of the Marvel universe or metahumans of the DC universe.
* SchoolOfHardKnocks: The separate school the traces attends seems to be a combination this and a SuperheroSchool since graduates can join trouble extermination groups, and the more violent traces tend to duke it out with little to know immediate consequences(though it might just apply to Cha Mi-ri becaue her father's a [[ScrewTheRulesIHaveConnections politican]].
* SuperRegistrationAct: The government does this with all traces, any that don't comply if found get arrested and shipped to a prison for a few months.
