User blog comment:Dark Knight 178/Stop giving Genders to Pokemon. It is very Annoying./@comment-26262392-20150519033411/@comment-25162832-20150519101338

Robin is the gender you choose him to be. You can choose for him to be a male or female in Fire Emblem Awakening and Smash Bros for that matter. I choose a male Robin when I first played, so I commonly think of Robin as a male, and I think Nintendo does as well because that's the Robin they showed in the trailer for him and Lucina.
