Yes, Unit-02 was the first EVA to have blue blood, however they went back to red for Unit 03, which became infected then reclassified an Angel. And while you do have a good point about the shadow Angel, didn't he go in the shadow in the ground, then out the sphere? Still, I think that was the only actual Angel with red blood, not considering Rei. I guess I did forget about that one. I stand corrected.
