Did Bullseye say in a canon comic somewhere that aiming for the left eye is more challenging so that’s why he does it? I’ve read it in fanfics many many years ago so I don’t know if i’m confusing the two lol.
I'm never going to let anyone forget the left eye thing.
(So, to answer Nonnie, Bullseye did say one time the left eye was more challenging, but it was in a very specific case, not an absolute. But it's way funnier to make it a real thing in fandom space.)
