I really hope it is Morgana, simply because she would fit the role well and is known as the most evil sorceress. Some interaction between her and Zelena would be fun to see if that happens.

However I do like the idea of Mephistopheles, although I immediately get reminded of this guy: http://vignette4.wikia.nocookie.net/typemoon/images/8/86/FGO_Caster_scene.jpg/revision/latest?cb=20150707174202

And this also reminded me of Cthulhu... but that may be a huge stretch for the original Dark One. But it would be fun to see it sometime in the future.
