After four Olympic Games, I figure that Nintendo and Sega will keep doing this. And this will be the summer Olympics. Now, we had the same roster since Mario and Sonic at the Olympic Winter Games. Well, it's time for new characters. I'd want it to have some sports divide Males and Females, because that is what happens in the real olympics. But since I'm not sexist, maybe there could be an option to play co-ed. And since there are 16 boys and 4 girls, the newcomers will have 4 boys and 16 girls. Here are the newcomers:
Team Mario Boys
- Toad
- Diddy Kong
Team Sonic Boys
- Charmy
- Espio
Team Mario Girls
- Rosalina
- Toadette
- Dixie Kong
- Birdo
- Baby Peach
- Baby Daisy
- Candy Kong
- Zelda
Team Sonic Girls
- Rouge
- Marine
- Cream
- Wave
- Elise
- Zeena
- Cosmo
- Ulala
Now here are the rival matchups: The veterans will have the same rivals as before.
Toad vs. Charmy because bees take nectar from flowers, and as mushrooms are rooted to the ground, they can be close enough to a flower, except it is a fungus. Charmy being naive hates Toad for that.
Diddy Kong vs. Espio because Espio is good friends with the "Kremling" Vector. When Espio tells Diddy that Vector isn't a Kremling, he doesn't believe him, because Vector looks like one. Diddy can't take Vector as his rival because Uncle DK already took him.
Toadette vs. Cream because of Toad and Cream being the hosts of the Olympics in previous games. Now that there is the Male/Female separation for this, Toad and Cream can't be together, so Cream has to deal with Toad's counterpart Toadette.
Zelda vs. Ulala, two third party characters (well, I ran out of characters). At least they are from Nintendo and Sega respectively. At least Mario knows Zelda from Super Smash Bros. and Sonic met Ulala in the Sega All-Stars games. For having the one thing in common of coming from the wrong worlds, they agree to be rivals. Zelda will have her Twilight Princess design because that is how Mario and Sonic knows her best.
Rosalina vs. Elise, two human royalty. They compete for that reason. Actually, they were both also introduced in the last generation! While Rosalina appeared multiple times in the Mario series, this is Elise's first appearance since the retcon of her debut. This would mark their second Sonic appearance for both of them as Rosalina previously appeared in Super Smash Bros. for Nintendo 3DS/Wii U.
Candy Kong vs. Rouge, two characters for the furry fandom.
Birdo vs. Cosmo, Cosmo is a flower alien and Birdo is often partnered with Yoshi, who had grappled flowers with his tongue.
Dixie Kong vs. Marine. Dixie is a sidekick for Donkey Kong and I believe Marine is a friend of Blaze.
Zeena vs Baby Peach. Zeena is sensitive about her make up and could probably hurt babies.
Wave vs Baby Daisy. Just because in Sonic Riders Zero Gravity, Wave wished on a shooting star, and Storm asked about her age, as she was acting younger for her age in wishing on a star.
So, what do you think of this roster?
