Ivysaur (フシギソウ, Fushigisou) is a fictional creature from the Pokémon series. It debuted in the series' first generation as the second stage Grass-type starter Pokémon of Kanto, and represents that generation as a playable character (via Pokémon Trainer) in Super Smash Bros. Brawl and Super Smash Bros. Ultimate.
Ivysaur is the evolved form of Bulbasaur, and is categorized within the Pokédex at #002 as the "Seed Pokémon". Ivysaur appears as a moderately large, teal, quadrupedal saurian. 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 Versions, Bulbasaur is obtainable alongside its fellow Kanto starters Squirtle and Charmander under special conditions in Pokémon Yellow Version, 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.
Ivysaur is briefly mentioned in both Venusaur and Bulbasaur's trophy descriptions.

Ivysaur appears as a playable character Super Smash Bros. Brawl. It is one of Pokémon Trainer's three Pokémon, alongside Squirtle and Charizard. Ivysaur can be switched into or out of battle via Pokémon Change, which operates similarly to Transform.
Ivysaur, along with Squirtle, did not return as a playable character in Super Smash Bros. 4. However, it does appear in both versions of Super Smash Bros. 4 as a trophy.

As a playable character
Main article: Ivysaur (SSBU)
Ivysaur returns as a playable character as part of Pokémon Trainer, alongside Squirtle and Charizard, 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.
