the "pointy ear" trait is common because there is a high degree of Fay and Demon alteration of "mortal" species in Villains Multiverse.. many species have been corrupted or interbred.. resulting in typical elfin and/or demonic features appearing in many beings.

This further fuels fanatics like Oath into believing non-humans are "demons" because, technically, they are.. or Fay.. there's a reason Destiny Force is hard for science to grasp.. it has links with powers far beyond science.. the power of splinter realms and so forth.

In the case of Pegacorns, they have pointy ears due to "evolving" from equines.. or rather being envisioned as an equine-species when Avalon "gave birth" to them.

The distinctive dark pelt Inferno has is a trait of Twilight Corruption, this is seen in many characters that are corrupted by Twilight or Makers (Arodnap, King Equinox, Equis etc) .. they often start with the regular skin / pelt tone of their respective species then develop that dark pelt when they succumb to Twilight Corruption.. in the case of winged beings they develop "demonic" wings and if they are "blessed" by the Watchers they develop wild mutations such as multiple limbs, tendrils and a massive increase in physical mass (such as Equinox).
