Yoshi is a protagonist in Super Smash Bros. Crossover. He is a lovable dinosaur who is good pals with Kirby. Yoshi bravely fought against Dark Mario during the events of Season 6. In Season 13, Yoshi and Kirby are discussing the current situation when Psycho Kirby arrives. Kirby tells Yoshi to find some help while he battles against the Cannibal. However, Yoshi gets lost along the way and winds up at the N64 Race to the Finish with Mewtwo and Zombie Giant-Man. They later reunite with Naruto Uzumaki when he saves them from the Fighting Polygons. Yoshi later witnesses Vegeta's death at the hands of Sasuke Uchiha and Yoshi says they have to save Kirby. Along the way, they are intercepted by Samus, whose enhanced power has driven her insane. Yoshi, Naruto, and Trunks, who joined their group after his father's death, are told to get to Kirby while Mewtwo and Zombie Giant-Man fight Pichu and Zombie Spider-Man to avenge Pikachu and Zombie Wasp. Samus tries to stop them, but Yoshi kicks Samus hard as payback for not draining his energy. Yoshi and the others however, are unable to save Kirby once Dark Pichu, Zombie Spider-Man, and Samus arrive and watch helplessly along with Sakura Haruno and Meta Knight, who arrived when they sensed Kirby was in trouble, as Kirby is burned to death by Psycho Kirby. Yoshi is then determined to avenge his fallen friend. In Season 18, Yoshi is infected by the zombie plague offscreen. Yoshi is later killed during the final battle against Yami Bakura. Yoshi is later revived as one of Yami Bakura's reanimated soldiers. Oddly, Yoshi is not infected even though he died as such. Yoshi is revived by Shenron at the end of Season 19. At the end of Season 25, Yoshi becomes a Hero of Legend after Mechtavius Destroyer is defeated.
Yoshi's appearance is based off his modern day appearance in the Mario series.
- A running gag is that Yoshi is considered useless and that he has short-term memory loss. Ironically, Yoshi later becomes a Hero of Legend.
