As quoted above, SE tends to reuse the mob artworks and mechanics in other instances.. to save time on programming, animating and thinking of new mechanics. Mix and match apperances of a mob with mechanics of another.. add a pinch of hue and some decorations.. VoilĂ ! New Boss emerges!
Remember how you hate "Angra Mainyu" in WoD? .. he is the Ahriman from Hakkue who was tutored by 1st boss in Qarn to cast Doom.
