At the beginning I thought I was going to main Dark Pit and Doctor Mario, alongside Robin, Lucina, and Shulk. However, I quickly figured out that Dark Pit and Doctor Mario, while characters who were enjoyable to play with, didn't have a connection like Robin, Lucina and Shulk did. Robin, Lucina and Shulk come from two of my favourite games of all time, Fire Emblem: Awakening and Xenoblade Chronicles respectively and because of that connection with they're games and themselves as characters before even playing Smash Bros. 3DS, I was able to gravitate towards them more so than Dark Pit and Doctor Mario due to popularity, aesthetics, and the fact that I had such a deep connection with them long before I played them in the game or saw they're respective reveal trailers.
I've said this before in a previous thread, but my good friend on Smashboards, @
Wintropy, once told me, "You don't pick your main, your main picks you." Those words ring true for me given thats's how Robin, Lucina and Shulk became my three mains, despite them probably not being super top tier characters or perhaps even competitive characters. They resonated with me LONG before they became my mains. They spoke to me and connected to me as characters, establishing themselves as permanent mains long before they were revealed as playable characters. The great part about all of this is that they have REALLY fun and enjoyable move sets, which makes them even more of a pleasure to play with. Robin, Lucina and Shulk will NEVER not be my mains, despite tier lists or competitive viability, or anything else for that matter. They are here to stay and I couldn't be more happier because of that.
