Few characters are as unusual in Brawl as Yoshi. Yoshi is a rather
heavy character, tied with Wario in weight, but rather small and weak for his weight. He is also very maneuverable in the air, with a slow falling speed and the fastest horizontal air speed in the game - uncommon attributes for a heavy-weight. His midair jump is the largest in the game, giving limited
knockback resistance during its ascent. Tied with Wario, he is thought to have the fastest ground-to-air acceleration in the game.
Many have insisted that one of Yoshi's major flaws is that - because of his minuscule third jump - Footstool Jumps, grabs (such as special grabs that can catch in the air), and attacks with enough knockback to cancel his midair jump's resistance are devastating to Yoshi when he is trying to recover. This is quite false, however; Yoshi's up-air has incredible priority and super-armor frames, and can be used simultaneously with Yoshi's second jump. In essence, it works to make Yoshi's second jump function as an up-B that hits everything above and immediately to the sides with virtually transcendent priority. People do not understand this because they still aren't used to the fact that double jump cancelling is gone, so it does not occur to them to flick their tail as they are rising through the air. Once in this habit, however, it is literally impossible for any opponent to do any of the above before getting nailed by Yoshi's potent up-air (often resulting in a KO). Also, after being hit, Yoshi virtually always regains his second jump the way other characters regain their Up B. This renders the (nonexistent) issue of getting hit or grabbed on the way up irrelevant, as Yoshi can simply try again. Footstool hopping doesn't count as hurting Yoshi, so Yoshi won't regain his second jump - but if anyone tries to footstool hop an even remotely competent Yoshi, they will be sent into the ionosphere with no questions asked, so this too is not a concern. Furthermore, Yoshi can air dodge with his second jump, giving him the distance of his second jump while mitigating its lag, allowing Yoshi to capitalize upon having the fastest air speed in the game while covering substantial distance. He is also the only character in the game with a
fast recovery move that is also a projectile move (and hits the opponent with a projectile that is unrelated to the recovery), allowing him to exercise his projectile game while recovering. In short, it is almost literally impossible to edgeguard a competent Yoshi.
