The Heavy Lifter ("Strong" Female Characters)
I put the quotations because I don't necessarily like the word strong, but it's the one used by the host, so I'm going to roll with it.
Anyway, I have a few choices (yeah, I'm cheating. Deal with it. xD). Here we go! (I'm so excited!)
Note: These are my personal opinions, and even for some of these, which I won't point out, I could argue against, but bear with me.
