Powers and abilities

Superhuman Physical Characteristics
Demon Physiology (Sinner)

Energy Manipulation (Manifested energy slashes capable of destroying Sir Pentious's machine and cutting Baxter's artificial creature in half)
Darkness Manipulation, Intangibility & Pseudo-Teleportation (Much like Alastor, Zestial can melt into shadows to quickly move to different places)
Shapeshifting, Thread Manipulation, Stealth Mastery & Small Size (Type 1) (Can transform into a spider, allowing him to spy on Vox, Velvette and Carmilla's discussion whilst remaining undetected, as well as spinning webs)
Forcefield Creation (Alongside all the other Overlords, he helped to generate a forcefield to stop the Might of Lilith from exploding)
Summoning (Summoned a cup of tea)
