* Music/IllNino (third album onward, the TropeMaker for the subgenre as it was in the [=2010=])

* '''Mathcore''': Technical metalcore involving odd time signatures, dissonant chords (the fabled "panic chord"), and frequent GenreMashup tendencies. Famous acts include Music/{{Converge}}, Music/TheDillingerEscapePlan, Candiria, The Chariot, Car Bomb, and Botch.

* LongTitle: This was a pretty big trend in the genre for a while. Some of the worst offenders included Daughters, Norma Jean, Curl Up And Die, Shai Hulud, Botch, Coalesce, Integrity, Eighteen Visions and 7 Angels 7 Plagues. Candiria, Iwrestledabearonce and Burnt By The Sun were known to do this occasionally as well.
** Even Hatebreed got in on it with "Conceived Through An Act Of Violence", ''Satisfaction Is The Death Of Desire'', "A Lesson Lived Is A Lesson Learned", and a few tracks on their SelfTitledAlbum
** The kings of this trope are I Set My Friends on Fire, with catchy titles like "Words that Rhyme with Orange," "Reese's Pieces, I Don't Know Who John Cleese Is," and "My Uzi Holds a Thousand Rounds of Consciousness" (among many others).

* '''Melodic metalcore''': ''The'' most famous style in the genre, this started out as a mix of metallic hardcore and melodic death metal, sometimes with thrash metal influences; occasional elements of post-hardcore or alternative metal may also be mixed in. Characterized by melodic death metal-style guitar riffs, faster tempos, frequent guitar solos, and (for many though not all bands) greater use of clean vocals. Famous acts include Music/KillswitchEngage, Music/ShadowsFall, Music/AllThatRemains, Music/ParkwayDrive, Music/AsILayDying, and Music/{{Trivium}}.
* '''Modern metalcore''': This style of metalcore places much greater emphasis on its post-hardcore and alternative metal inclinations, generally featuring catchy choruses, somewhat greater use of breakdowns, and gratuitous use of clean vocals; many bands also embrace electronic elements. Some bands retain vestigial influences from melodic metalcore. Famous acts include Music/BulletForMyValentine, early Black Veil Brides, Asking Alexandria, Music/BringMeTheHorizon in the late 2000s and early 2010s, early Music/AvengedSevenfold, Atreyu, Of Mice & Men, and Music/MotionlessInWhite.
** '''Progressive metalcore''': A spinoff of modern metalcore, typically involving more technical guitar work and more atmospheric synths, as well as featuring extremely prominent djent elements. Famous acts include Architects, Erra, later Born of Osiris, Northlane, Invent Animate, and later Veil of Maya.

* '''Entombedcore''': A blend of old-school metallic hardcore, old-school death metal, and often crust punk or powerviolence, typically involving the "chainsaw" guitar sound of old-school Swedish death metal (hence the reference to Music/{{Entombed}}). Famous acts include Music/TrapThem, Music/{{Nails}}, Cursed, All Pigs Must Die, Sect, and Wolf King.

* Paleface (slamming beatdown with hints of NuMetal)

** '''Slamming beatdown''': A microgenre that has solidified as of the late 2010s, slamming beatdown is ExactlyWhatItSaysOnTheTin: beatdown hardcore crossed with slam death metal, and is distinctive enough to get a mention. Most acts come from the hardcore side, but a few come from the death metal or deathcore side and skew closer to slam, using more traditional death metal gutturals (and, in the case of deathcore-based acts, atmospheric leads and occasional deathcore breakdowns). Famous acts include Bodysnatcher (the ''Death of Me'' reissue bonus tracks onward), No Zodiac, Dysentery, Acranius, The Merciless Concept, and Paleface.

* '''Melodic metalcore''': ''The'' most famous style in the genre, this started out as a mix of metallic hardcore and melodic death metal (and sometimes thrash metal) before it began to embrace post-hardcore and pop-punk elements. Characterized by melodic death riffing and the frequent usage of clean vocals. Famous acts include Music/KillswitchEngage, Music/ShadowsFall, Music/AllThatRemains, Music/ParkwayDrive, Music/AsILayDying, and Music/{{Trivium}}.
* '''Modern metalcore''': An offshoot of melodic metalcore, this took the catchy choruses and pop-punk dabblings of many of the original acts and emphasized them, while mostly eschewing the melodic death elements and frequently embracing electronic elements as well. Famous acts include The Devil Wears Prada, early Music/AvengedSevenfold, Music/BulletForMyValentine, Atreyu, Asking Alexandria, and Music/MotionlessInWhite.

* Music/NoFaceNoCase

* Paleface (slamming beatdown)

* '''Entombedcore''': A blend of old-school metallic hardcore, old-school death metal, and often crust punk or powerviolence, typically involving the "chainsaw" guitar sound of old-school Swedish death metal (hence the reference to Entombed). Famous acts include Music/TrapThem, Music/{{Nails}}, Cursed, All Pigs Must Die, Sect, and Wolf King.

* Music/TheHaunted: Often mistaken for metalcore thanks to A) forming from the ashes of Music/AtTheGates, one of if not the most influential bands on melodic metalcore, and B) both of their vocalists having a lot in common with the genre (Peter Dolving uses cleans occasionally and comes from a punk background, while Marco Aro has a very hardcore-esque tinge to his vocals). However, their music is melodic death/thrash with some influences from groove metal, with the exception of the experimental ''Unseen''.

* '''Mathcore''': Technical metalcore involving odd time signatures, dissonant chords (the fabled "panic chord"), and frequent GenreMashup tendencies. Famous acts include Music/{{Converge}}, Music/TheDillingerEscapePlan, Candiria, The Chariot, Car Bomb, and Norma Jean.

Metalcore (also known as "metallic hardcore" or erroneously referred to as "screamo", names given to the more punk-influenced bands) is a combination of HeavyMetal, ThrashMetal and HardcorePunk, and sometimes takes a more melodic approach to the songs than thrash. It is characterised by gratuitous use of the MetalScream, as well as breakdowns. Lots and lots of breakdowns (although due to, ahem, certain bands, this attribute has been {{Flanderized}} a bit). If you're not in the know, a "breakdown" is when the music kind-of slows down to induce moshing or "throwing down"...or something like that.

* Earthists (also djent, notable ambient influence)

* Sylosis: The confusion comes mainly from their vocalist's screaming style, as well as their time of emergence and their tendency to tour with melodic metalcore acts. Musically, however, the band is ThrashMetal with some elements of DeathMetal and ProgressiveMetal.
