Game 1. King K. Rool
Impa is really cool and I wouldn't mind seeing her, but King K. Rool also has potential and the fans have been requesting him for a while.
Game 2. Takamaru
It would be nice seeing another character get boosted popularity through an inclusion in Smash, and I think that would happen for Takamaru. He has a likable design and I also think he would fit in well. Though this is very close, as I really want to see Captain Toad get in too.
Game 3. Decidueye
Decidueye would work well as an archer in Smash. He has different moves he could use and even some exclusive ones such as Spirit Shackle which could be a special that pins down the opponent. A new Pokemon is almost inevitable and I feel like Decidueye is one of the top candidates for this. Though there are other good Gen VII options such as Lycanroc, Mimikyu, one of the Tapus, and an Ultra Beast.
Game 4. Rex & Pyra
This is very hard for me since I really want Waluigi, but I think Xenoblade is big enough for a second rep and these two could represent the Driver and Blade system. Mythra could also be implemented and I want to see how they handle this. Will Pyra be in the background or would they work like a duo character?
Game 5. Andy
Advance Wars from what I've heard was considered a great game especially when it released. More representation for the GBA era is fine with me and Andy could be fun to play as.
Game 6. Isaac
Even though I haven't played Golden Sun, I've wanted to see Isaac for a while. Maybe Ballot results will make it happen.
Game 7. Bandana Waddle Dee
Bandana Waddle Dee is one of the main characters of Kirby at this point, there aren't any spear users in Smash yet, and he has support to back him up. He's personally one of my most wanted newcomers this time and I hope to see him playable this time.
Game 8. Dixie Kong
I really want to see Ashley, but I also think that Dixie Kong deserves to get in now. She is one of the the lead protagonists of the original Donkey Kong Country trilogy, alongside Donkey Kong and Diddy Kong who are both already playable. She also made a playable appearance in the latest game Donkey Kong Country: Tropical Freeze. Whether she would be unique or a semi-clone of Diddy Kong, I want her to be a newcomer.
While I can see who will win some of the games this round, I think it is hard to predict other ones. Anyways, those were just my votes on who I'd like to see, though it has come down to multiple characters I want to see competing. I would be fine with any of the ones remaining becoming newcomers.
