I see people have been talking about mains.
Became my favorite Pokemon after I found out he was playable in Melee. Also because he was the most powerful Pokemon back in the day and I liked having a cool legendary on my team in Red. Also a fan of the first movie. Too many reasons to like him.
Was the last character for me to unlock in 64. Back before I knew how to use the Internet, I thought the last slot was Wario or something and could never figure out how to unlock the character. One day I played Smash at my cousin's house and he had every character unlocked. He showed off Ness, and I thought it was cool to play as a kid like I was. Also, I thought he looked Asian. Since then, Ness has been one of my mains in every Smash game. When I finally got to play through EarthBound, the Mother series became one of my favorites. I've loved its music since I first heard some Mother music on the Onett stage in Melee.
My main reason is
. I don't care if it's the worst counter move, I like trying to summon the doll. Also, Greninja is fun to play, water starters have been my favorite since gen 2, etc.
I loved Mother 3. That's pretty much my main reason. A little different from Ness too.
Because I mained Pokemon Trainer in Brawl. Also, first starter ever for me was Charmander. While I'm not great with slow but strong characters, as a fan of Pokemon and growing up with gen 1, I'm playing as him sometimes.
Samus is cool, and I love the Metroid series. I haven't played Other M, but I've played all the other games.
Tipper, speaks Japanese, feels comfortable to use, enjoy the representation of the Fire Emblem series and how he basically defined it. Also, his appearance in Melee is what brought the series to the west.
Like her as a character in FEA. Also, I love her alternate costumes.
Some honorable mentions:
because her reveal trailer was animated by Shaft.
Costumes, cool way for representing Fire Emblem, etc.
Because I like the music from Mario Galaxy 1 and 2, and I like using characters on their home stage.
The Monado, costumes, and because a friend hyped him up for me.
Was my main in 64 before I learned about Ness. Has some cool hats. Still easy to use considering Pichu was one of my mains in Melee. Also, I got a Pikachu Amiibo and named him Pikabro while wearing an Ethan hat. He might be better than me at this point.
