@lombiegee replied to your post “I’m thinking about the popular eva post that occasionally floats...”
Would the Evangelion's themselves even qualify as some sort of eldritch horror? Just asking out of curiosity!
Unit 01 looks pretty horrific unarmored (i.e. in episode 19 before Dinner Time if you catch my drift). As for the other Evas (save for the MPEs), not so much. It may be because the intention of those mothers (save for Rei, since she’s a clone) in the Evas aren’t geared at Instrumentality.
Yui isn’t herself nightmare fuel on her own and neither is Unit 01. You’d have to put them together, realizing that Yui was trying to make Instrumentality come to fruition using the Evangelion as her vessel. Yui knew what she was doing in basis of using that vessel and her basically overkilling Zeruel was on a whim if anything in action that can be described as savage and intelligent. I think that is where Unit 01 cements her status as eldritch.
