Rio

Not to be confused with Mario and Sonic at the Rio 2016 Olympic Games.

Rio is a pop idol trumpet player from Samba de Amigo and one of Amigo's close friends.

Appearance
Rio is a tanned skinned slim feminine looking character who wears a collared cheetah-print leotard complete with tail and high heels. He wears a diamond necklace underneath his leotard, a matching set of bracelets on both arms and wears yellow eyeshadow and lipstick. He wears his hair in a feminine bob hairstyle.

He appears to have a pair of pointed cat ears with cheetah print on them, although much like Linda, it is hard to tell if he is actually a cheetah or it's a costume, as there are two other cheetahs named Chumba and Wamba who play in the band, and their appearance is completely different.

Rio is rarely ever seen without his trumpet or a rose in his hand.

History
Rio was formerly the most popular Pop idol and he can't help but to act like a show-off. But once you get to know him better, he is actually an all-around good guy who's always chasing his dreams. To bring him the luck he needs, he continues to eat onion rings every morning.

He forms a Samba troupe with Amigo and Linda.

Trivia

 * For whatever reason, Rio tends to be missed out of crossover cameos. He is absent from Sega Superstars Tennis, Sonic Riders, Sonic & Sega All-Stars Racing and Sonic & All-Stars Racing Transformed. He is the only main character from Samba de Amigo to not appear in the latter title, with Linda appearing in all of these crossovers, Chumba, Wamba, Bingo and Bongo appearing in every one bar Sonic Riders, and Amiga appearing in both racing titles.
 * Rio's gender was the cause of much confusion amongst fans for a long time, although the official manuals refer to Rio as male.
 * Rio's status as the previous most popular pop idol likely means he was upstaged or replaced by Amiga, Amigo's little sister who appears to be the most popular pop idol in Samba de Amigo at current.
