I pretty much love everyone, lol. There's only three characters in the game I actually dislike, so I'll just make this a simple top ten for the sake of time and post length.
10.
(DEDEDE, THAT'S THE NAME YOU SHOULD KNOW! DEDEDE, HE'S THE KING OF THE SHOW!)
9.
(He's one of the funniest characters on the roster, IMO. I always have a blast playing as this guy.)
8.
(There was a short period back in Brawl where I played him a lot, and him being in the game is what got me curious in Pikmin.)
7.
(The best Link. He's just such a lovable little dork.)
6.
(I've always unironically loved Pichu and wanted him back. Needless to say, I am very excited to play him in Ultimate, and would love if he somehow ends up good, lol.)
5.
(Metroid is probably in my top 5 franchises of all time, and Samus is just super fun to play in Smash. If it weren't for all the other characters I like putting time into, Samus would probably be one of my most played secondaries.)
4.
(She's a pure doggo. 'Nuff said.)
3.
(I've been playing Luigi in Smash for as long as I could hold a controller. Heck, Luigi's is one of my most video game characters period, so I honestly don't think I will ever stop playing as him in Smash Bros.)
2.
(My all time favorite video game character. Like Luigi, as long as he's in Smash, I will never stop playing as him. I may be replacing him as my main with Inkling, but he's still gonna always be in my character rotation.)
1.
(They're cute, they're stylish, they're awesome, they're the Inklings. Gosh, what can I really say about them that I already haven't? Splatoon really has surprised me with how much I've grown attached to it over the past couple of years, and I pulled for these guys so hard during the ballot days. Seeing them make it in, and the very first revealed, no less? That was a pretty magical moment I don't think I'll ever forget, ha ha.)
