History Characters / LimbusCompanySinnersSevenToThirteen

** He uses a slightly different sanity mechanic compared to other Identities, which has the same conditions but a greatly increased gain/loss, making it easier for him to raise his sanity, but also easier for him to lose it if his allies are slain.

* MechanicallyUnusualFighter: Uniquely to most [=ID=]s, this version of Sinclair has access to two movesets, his first being the standard moveset, while his second has him manifest his EGO for even stronger attacks.
* MythologyGag: An alternative condition for him to awaken his Volatile EGO during combat is if two other Sinners die in the same turn - mimicking how Philip actually awakened his EGO in ''VideoGame/LibraryOfRuina''.

-> '''Sinclair:''' You're wrong, [[spoiler:Miss Carmen]]. I'm afraid. I'm so afraid that I want to let go of this blade and flee this place at this very moment. But I don't want to linger here any longer. [...] This feeling... is destiny bestowed upon me... I have to soar. I will break this shell that stands in my way. I'll break it altogether and soar to a higher place.
* SuperMode: Once he hits 45+ SP, he obtains his Volatile EGO, empowering his moves and transforming his third skill into Blazing Strike - however, [[CastFromHitpoints his second and third skills consume SP once he transforms]] - and once his Sanity reaches 0 or below, he returns to his normal mode.

* SuperMode: Once he hits 45+ SP, he obtains his Volatile EGO, empowering his moves and transforming his third skill into Blazing Strike - however, [[CastFromHitpoints every action he does consumes SP once he transforms]], including his defense skill - and once his Sanity reaches 0 or below, he returns to his normal mode.

* BreakingOldTrends: This is the first [=ID=] to have the description of Volatile rather this Effloresced. [[spoiler:This is likely due to the fsct that Philip's E.G.O. back in Ruina remained incomplete and thus only partially summoned, unlike other E.G.O. users we've seen across both games.]]

* DumbMuscle: Played with. He's noted to be simple-minded by his description, preferring action and violence over logical thought, poses a handful to manage and even a physical threat to those near should his anger overwhelm him. While not quite an idiot, it's clear that his emotional outbursts get the better of him far too often. Throughout the chapters he's shown to be quite intuitive about certain situations, and is even able to deduce the cause(s) of murder when investigating the old L Corp. building in Canto I just from a preliminary glance. While overall he's not the most book smart of the Sinners, he's shown himself to be capable of some rather clever moments.

* EnragedByIdiocy: He was prepared to beat Hong Lu to death with a tenderizer for saying that potatoes grew on trees (he thankfully turned out to be joking.) Ironic, considering Heathcliff's own DumbMuscle tendencies.

* UngratefulBastard: Of all the Sinners, Heathcliff is the most overt in thinking he doesn't owe Dante any respect even though he'd be dead several times over without them, since it's their job to revive him.

* BookDumb: [[DownplayedTrope Downplayed.]] He's got zero formal education, so the first thing he does when the crew is told their next mission is in K Corp's Nest is complain that he was never told that there were mandatory education requirements for the job. That said, he's actually quite clever and quick on the uptake as evidenced by his skills at reading people and figuring things out on the fly, the latter in particular when [[spoiler:he opts to ''stab himself'' with the Golden Bough to communicate with Catherine's unhoused soul in the climax of Canto VI]]. Tellingly, he has Identities where his latent intelligence is properly cultivated, such as in the Seven and Öufi Associations.

* BrutishCharacterBrutishWeapon: He's a barbaric brutish jerk and his weapon of choice is a scuffed metal bat that deals pure Blunt Damage.

* JackOfAllStats: She has a ''lot'' of things packed in her kit, including Bleed, Poise, Offense Level Up, Aggro, Burn, specific forms of Power Up and even Assist Attack (which can be best described as a better form of [[VideoGame/MagiaRecordPuellaMagiMadokaMagicaSideStory chase]]). Due to this, it is difficult to slot her in one category and can fulfill a role in a Bleed team but also one in a Burn team.
