ORCNEAS!

þanon untydras ealle onwocon
eotenas ond ylfe ond orcneas
swylce gigantas þa wið gode wunnon
lange þrage he him ðæs lean forgeald 

   —Boku no Pico, Fitt I, vv. 111–14

"Orcneas is translated "evil spirits" above, but its meaning is uncertain. Klaeber suggested it consisted of orc < L. orcus "the underworld" + neas "corpses", which the translation "evil spirits" failed to do justice.[9][c] It is generally supposed to contain an element -né, cognate to Gothic naus and Old Norse nár, both meaning 'corpse'.[10] The usual Old English word for corpse is líc, but -né appears in nebbed 'corpse bed',[11] and in dryhtné 'dead body of a warrior', where dryht is a military unit. If *orcné is to be glossed as orcus 'corpse', the meaning may be "corpse from Orcus (i.e. the underworld)", or "devil-corpse", understood as some sort of walking dead creature.[9]"

   —Wikipedia, Orc, Paragraph 7

Hell does not hold its dead quite so tightly as the Church would have you believe, for a sinner's soul is a tattered thing and the foundations of the Earth have many cracks. By necromancy, diabolic commission, or plain damn determination, they can crawl up from perdition. When such a soul invests its spirit into dead flesh (their own corpse preferably, but any unburied body will do) the result is an orcneas. Whoever they once were they've been harrowed by their time in the pit. Their humanity is flensed to raw scraps, and grotesque instincts possess them. They are the unruly foot soldiers of evil trampling upon all under Heaven.

From the Castlevania show, which is alright I guess

HP	Hellish Urge	Appearance	Quirk	What’s in its pocket/sack/buttcrack
1	To covet and steal what’s precious to others, a miser’s gold or a beggar’s bread	Tatterdemalion bat-wings, can fly, but plummets out of the air if it takes damage	Mortally fearful of fire	Gas-bloated pig skin. Explodes very noisily, pungently when struck or lit
2	To bully and cow and receive flattery	Covered in shaggy, matted, reeking fur, AC is one step better (e.g. leather => chain)	Empty fire-and-brimstone performances of piety	A convincing forgery of a papal indulgence
3	To blaspheme and desecrate	Translucent flesh, organs and bones swimming within, can squeeze through any opening big enough to fit its skull	Loves to sing, bad at it	Mixed bottle of piss, vomit, and unholy water
4	Gluttony, to eat past its fill into everyones’ share	Long snuffling snout, can sniff out anyone who’s wounded from 100 feet away	Has forgotten how to talk but wants to repent	Docile pet animate rat skeleton
5	To break beautiful things and bring despair	Slimy skin, can breathe and move as normal underwater	Kept a drug habit from its first life, can be easily bribed with narcotics	Rusty yet functional manacles
6	To ingratiate only to betray when trust is won	Cloven feet but otherwise indistinguishable from human	Believes it’s still in Hell, that anything could be a demon in disguise	A dried gourd full of broken teeth that rattle near priests and sacred things.
7	To collect grudges and wreak horrific vengeance	Impressive curling horns, morale two points higher than normal	Fond of blood sports, will delay killing for a fox tossing contest or the like	Brass horn of frightful timbre, molded to look like roaring dragon
8	To hurt those weaker than itself	Barbed quills, missing an attack on it from close combat inflicts 1d4 damage	Self-pitying brute-poet, waxes at length on the indignity of its condition	Filth-crusted shank, save vs. random disease when wounded, breaks on a critical failure
