Ivysaur

Ivysaur (, Fushigisou) is a Seed Pokémon from the series. It debuted in the series' first generation as the second stage Grass-type of, and is present as a playable character (via Pokémon Trainer) in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.

Origin
Ivysaur is a dual Grass/Poison-type Pokémon and the evolved form of, and is categorized within the Pokédex at #002 as the "Seed Pokémon". Ivysaur appears as a moderately large, teal, quadrupedal frog-like Pokémon. It evolves from Bulbasaur evolves at level 16 onward, and then evolves into Venusaur at level 32 onward.

However, unlike in Pokémon Red, Green, and Blue, Bulbasaur is obtainable alongside its fellow Kanto starters and  under special conditions in , and relatively early on in Pokémon X and Y.

Unlike Bulbasaur, the bulb on Ivysaur's back has partially bloomed into a pink bud with large green leaves, thanks to exposure from sunlight and apparently from drawing energy from Ivysaur's own body. The budding flower is heavy enough that Ivysaur has difficulty standing on its hind legs, but its four legs and torso grow thick and strong from the weight of the flower, even as a quadruped. Aside from assisting its bud's growth, sunlight also increases Ivysaur's strength.

If Ivysaur starts spending more time lying in the sunlight, it is a sign that the bud will bloom into a large flower soon, which would be heralded by the bud giving off a sweet, pleasant aroma and the species' evolution into its final form, Venusaur.

In Super Smash Bros. Melee
Ivysaur is briefly mentioned in both Venusaur and Bulbasaur's trophy descriptions.

Trophy
In, the Ivysaur trophy is part of the Pokémon Classics.

As a playable character
Ivysaur returns as a playable character as part of, alongside and , in Super Smash Bros. Ultimate. Like Squirtle and Charizard, it is no longer subject to stamina, and thus remains effective throughout a fight. Unlike Brawl, Pokémon Trainer is an unlockable character instead of a starter character.

Ivysaur was previously considered the worst Pokémon in the Pokemon Trainer's party and one of the worst characters in Brawl (especially if judged as a standalone fighter), due to its large amount of significant weaknesses, namely short range on its attacks, notable KO problems due to laggy finishers, a bad aerial game, a terrible recovery, and one of the worst special movesets in the game. Likely as a result of this, Ivysaur has been heavily buffed in its transition to Ultimate and is now considered the best Pokémon in the Trainer's arsenal, gaining notoriety in the community thanks to its up and down aerials.
