Well, some of them are secondary mains. I guess I didn't say that right. I mostly use Lucas, Dark Pit, and Peach. But my secondary mains are Roy, Robin, and Shulk. I wish you good luck with maining Bowser.
Thanks! He will be my secondary. My advice to you is to main one person and get really good with him/her, then pick up a secondary.
Thanks for telling me this, but unfortunately, I'm not into SSB4 that much right now. But I'll let you know when I'm ready. ^^
