Hrm, that’s tough. Samus is definitely up there for a couple of reasons. You know, awesome powered suit, 80’s epaulets, armor cannon, etc. Hrm. I don’t know that I necessarily have a favorite? It would probably be my OC armored lady tank I play in most MMO’s honestly. But besides Samus and my OC I’m generally a big fan of..
Those are just some off the top of my head, I’m sure I’m forgetting tons.
tl;dr my favorite is my OC, made some notable mentions.
I would love to, trust me. it’s not due to a lack of motivation. It’s hard for me to find sourceable ladies in armor (reasonable armor) unless I decide to branch out to ladies in less reasonable armor (exposed breasts/chest, pointy plate mail that would likely kill them if they fell down, etc)
