In Black, I went with the girl, since I loved her tomboy design and overall she just seemed pretty radical. I believe I named her Jester, since I can't fit my real name in the digits provided pfff.
In White, I believe I chose the boy. I named him Torin, which would have been my name if I were a boy. Besides Brendan, I felt as though he had the best male design. The others I weren't a big fan of. :c
In White 2, I went with the girl again and I don't remember what I named her pffff. But I remember refusing to choose the guy, because I just couldn't, for the life of me, figure out how his hair worked with his visor. xD
