I also imagine that she's the only one that actually looks forward to fighting in enclosed spaces, everyone that has to fight alongside her is like AW MAN BUT THERE'S SMOKE EVERYWHERE AND IT'S SUPER GROSS and she doesn't really care all that much because she's got mechanical lungs :P

Also I picture her pretty much always having a cigar on the go. Cigarettes are too small to pick up without crushing with her MEC fingers.
