Ivysaur (Japanese: フシギソウ Fushigisou) is a dual-type Grass/Poison Pokémon.
It evolves from Bulbasaur starting at level 16, and evolves into Venusaur starting at level 32.
Ivysaur, like its pre-evolved form Bulbasaur, resembles a toad or a dinosaur, though the patches in its skin cause it to more closely resemble a dinosaur. After evolving from Bulbasaur, Ivysaur grows small fangs. Ivysaur's skin is also a little bit more blue than Bulbasaur's. When its plant is ready to bloom, it gives off a distinct aroma and starts swelling. Ivysaur will also start spending more time in sunlight in preparation for its upcoming evolution. Its plant is also an indicator of its overall health as when it grows, Ivysaur absorbs more nutrients.
Unlike its previous form, Bulbasaur, Ivysaur can no longer stand on its hind legs due to the bulb getting larger and heavier and its legs have grown thicker and stronger.
Gender differences
None.
Special abilities
Much like its previous form, most of Ivysaur's abilities originate from the plant on its back. Naturally, these attacks are stronger than Bulbasaur's. Its abilities are such like petals, powders, and scents than vines and leaves, most likely because of the larger flower on its back. In the anime, Ivysaur are shown to manipulate nature.
Behavior
Being much more commonly found in captivity then in the wild, Ivysaur's natural behavior is largely unknown, but it can be theorized that they are more aggressive then Bulbasaur, although it is still very loyal to its trainer.
When Ivysaur is ready to evolve, it starts spending more time in the sun to absorb more nutrients. It also releases a strong sweet-smelling odor.
Habitat
Grassland Pokémon
Ivysaur's natural habitat seems to consist of plains with access to large amounts of sunshine and fresh water but can be found in forests and jungles. However, they are rare, as many are in captivity.
Diet
Like its pre-evolved form, Bulbasaur, Ivysaur can last many days without eating, because it can absorb the sun's energy through the flower on its back.
