So I know we have Lesser, Greater & Hound demons for the "generic" ones & then we have Succubi/Incubi, Imps & whatever Big Red is for unique demons bit I hope we get to see new demons later. Perhaps ones based on sins & or negative emotions (like in Dragon Age) demons could still have a vague look similiar to the Lesser & Greater Demons but with different skin tones, horns/crests, differing number of limbs ect...
Demon types I would like to see, either as tougher enemies or bosses/mini-bosses:
-Gluttony: Fat, morbidly obese demons with a wide mouth & mouths instead of hands. Orange skin.
-Sloth: Grey skin demons with six arms & a half-moon crest covering there forehead.
-Greed/Avarice: gold or yellow skin demon with four arms & a "crown" of horns. (Could have this appear in the Dwarf Girl arc as a Balrog type demon that coused "gold fever" in a clan, killing them all through greed)
-Lust/Desire: Pinkish demons that have curved horns & a futa body (feminine shape, breasts & wide hips but a terrifying, rock hard cock), they would make for creepy enemies that would fit a porn game.
-Wrath: bulky demons wreathed in flames with cracked, burning skin & thick horns (loom kinda like a modern devil, but still looking like the Greater/Lesser demons).
-Envy: Green demons with glowing eyes that have really long arms & curly horns. Perhaps they can shapeshift? For some story elements that could be interesting.
-Pride: Huge, purple demons with a muscled physique & large horns. Covered in spikes & an intimidating silhouette.
Would love to start fighting some Angels as well at some point, perhaps in service to the Lord of Light; have some Cherubs, Maleks, Archangels, Ophanim, Seraphim ect being sent down or summoned by Purifiers/Priests to aid in battle!
