@VinMcCarthy In a zombie apocalypse who would I want by my side? Erza Scarlet of course! Not only is she excellent swordsman and expert at requip, she also has a relentless spirit and would never give up during a fight if the ones she loved were in danger. Not to mention she has a lot of awesome armor one of them being heavens wheel armor where she could take out multiple zombies with an armada of swords.
She can also strike fear into the hearts of grown men and women. I mean when she was introduced she was carrying a huge horn/tusk that was maybe 10x her size on one shoulder like it was nothin'. Erza, along with Gray and Natsu, took down a whole village. Also she fought 100 monsters by herself, kept fighting minerva and the metallic dragon babies even with a broken foot and beat etherious kyoka with no sight, sense of touch or hearing. Who wouldn't want this wicked awesome warrior by their side if there was a zombie apocalypse?
