Boshi

"What're YOU lookin' at? If you wanna challenge me, you have to bring Cookies!" -Boshi, Super Mario RPG: Legend of the Seven Stars

Boshi is blue Yoshi with an attitude. He is also the rival of Yoshi. Boshi is a loner who likes to wear a spiked collar around his neck and wear cool shades. He (along with many other Yoshis) live on Yo'ster Isle, home of the famous Mushroom Derby races.

One fateful day, Boshi defeated all the other Yoshis in a race and became the champion of the Mushroom Derby. Boshi then declared himself boss of the Yoshis. Under his reign, the races of the island were cancelled. In fact, the only one allowed to use the racetrack was Boshi himself. Although the other Yoshis disliked Boshiâ€™s rule, they felt obligated to obey the champion of the derby.

During the events of Super Mario RPG: Legend of the Seven Stars, Mario travels to Yoâ€™ster Isle via the Pipe Vault. Once there, Mario meets up with his old friend Yoshi. The green Yoshi delivers the bad news, and Mario decides to help free the island. Thankfully, Yoshi recognized that Boshi had a weakness for Yoshi Cookies. Yoshi asked a friend to loan him some cookies and Yoshi and Mario confronted the boss of the island. If Yoshi could win a race against Boshi, then he would become the new champion of the Mushroom Derby (as such, Boshi would lose his authority). Boshi, who would never decline a wager with Yoshi cookies on the lines, agrees to a race.

During the race, Mario rode on Yoshiâ€™s back, helping his old friend defeat Boshi. To beat the blue Yoshi to the finish line, Yoshi had to move to the beat of the derbyâ€™s music. As the music plays, the player must alternate between the A and B buttons with the musicâ€™s tempo. If the player presses the buttons too fast, Yoshi will not move. Unfortunately, as the song plays, the beat may stop or change. However, the player must continue pushing the buttons to the original beat, not the new beat. Additionally, if Mario has any additional Yoshi cookies, he can feed them to Yoshi, giving the green dinosaur a boost of speed.

Ultimately, the race was close but Yoshi proved to be the victor and became the champion of the Mushroom Derby. The other Yoshis congratulated the champion and demanded he become the new boss of the island. Yoshi, as humble as ever, declined the offer, stating that the races should be free for everyone to participate, not controlled by a boss. Yoshiâ€™s words even reform Boshi, who agrees to participate in fair competition.

Ever the loner however, Boshi still likes to stick to himself. However, he has learned to enjoy the spirit of competition. Proving he is still a good runner, Boshi still manages to win a race every once and a while. However, he is not the dominant racer he made himself out to be.

Boshi, like many other Yoshis, can only speak the Yoshi language. Thankfully, Yoshi is bilingual and can translate Boshiâ€™s words for Mario.

In Japan, Boshiâ€™s name is Washi, created by combining the word Yoshi with â€œwaruiâ€, the Japanese word for bad. As such, Boshi is to Yoshi as Wario is to Mario or Waluigi is to Luigi.
