Yoshi Team
The Yoshi Team is a group of variously-colored Yoshis that appears in some way in three of the four Super Smash Bros. games. Generally, the Yoshi Team appears in groups of two or three, with each member having below-average strength, particularly in lower difficulty levels.
In the Super Smash Bros. series
Super Smash Bros.
In Super Smash Bros., the Yoshi Team is made up of 18 multi-colored Yoshis. They are the second opponent(s) the player faces in the 1P Game after Link. The Yoshis rarely attack, are very weak, and will get sent flying from almost any attack. They tend to jump in random directions, often off the edge. KOing them in the order they appear yields the Yoshi Rainbow bonus.
If the player is using Yoshi, then the members of the team that match the player's color will be given a light colored tint; similar to the method of distinguishing two players of the same character on the same team.
The Yoshi team also boasts two unique alternate costumes, blue (not to be confused with the cyan costume) and pink. Blue Yoshi and Pink Yoshi though are only playable on Stage 2: Yoshi Team (playable as an opponent character and CPU). But Yoshi's alternate costumes are red, yellow, green (default), and cyan. The Cyan Yoshi is used when Yoshi is on the blue team in Team Battles.
Super Smash Bros. Melee
In Super Smash Bros. Melee, the Yoshi Team re-appears in the Adventure Mode, about halfway through the Mushroom Kingdom stage. There are only ten Yoshis in the team this time but act mostly the same. However on Classic Mode, the Yoshi Team is not a multi-character opponent on Stage 8. It does not return on Classic Mode in Melee (despite its frequent appearance on 1P Game in Super Smash Bros.).
A complement of 30 Yoshis appear in The Yoshi Herd, SSBM's 24th Event Match, with the final one being a giant.
Super Smash Bros. Brawl
In Super Smash Bros. Brawl, the fifth Co-Op Event Match is The Yoshi Team of 50. The largest Yoshi Team thus far is even easier to KO than its predecessors, but on higher difficulties, the significantly reduced time alloted - combined with Brawl's relatively slow loading times - can make them quite challenging. There is also a mini-team of 6 Yoshis in Event 11: Yoshi's Rainbow, which must be KO'd in a colored order similarly to the Yoshi Rainbow bonus.
Outside of the events (Event 11: Yoshi's Rainbow and Co-Op Event 5: The Yoshi Team of 50) the Yoshi Team along with Giant DK, do not appear as opponents in Brawl's Classic Mode; despite their frequent appearances in 1 player modes from Super Smash Bros. and Melee.
