Bulbasaur resembles a small, squatting dinosaur that walks on four legs and has a large bulb on its back that is able to shoot seeds out of. It also has large red eyes and has very sharp teeth. Its skin is a light turquoise color with dark green spots. It has three claws on all its four legs. Its most notable feature, however, is the aforementioned bulb on its back, which as the Pokédex states, was planted on it at birth.
Bulbasaurs have “bulbs” on their backs that grow steadily larger as the Bulbasaur matures. This bulb contains a seed which uses photosynthesis to supply Bulbasaur with energy. Its bulb is also used to store the energy which the seed absorbs, which can be used when it is necessary. It is assumed that when a Bulbasaur collects enough energy in its bulb, it will evolve into an Ivysaur.
Bulbasaur is very polite Pokémon. They are very loyal to their trainer and always try their best to win the battle for them.
As Bulbasaur is a starter Pokémon, it is hard to locate, however, it could be found near streams.
Ivysaur’s appearance is very similar to that of its pre-evolved form, Bulbasaur. It still retains the turquoise skin and spots, along with its red eyes. Ivysaur’s top fangs are now larger and are visible outside of the mouth. Also, its ears are now darkened to black in the center. The most notable change is that the bulb is starting to bloom, with pink petals visible, and large leaves on the bottom.
Ivysaur’s ability is Overgrow, which increases the power of Grass-type attacks by 50% once the Pokémon has less than one-third of its maximum HP.
The bud that it carried on its back as a Bulbasaur has grown into a full blossom when it had evolved and can grow larger in sunlight. As the blossom grows, Ivysaur loses the ability to stand on its hind legs. The blossom produces a pleasant smell when it is ready to bloom, and Ivysaur is ready to evolve into Venusaur.
Venusaur is a large dinosaur like Pokémon that is somewhat similar in appearance to its pre-evolved forms, Ivysaur and Bulbasaur. Its skin still retains a light turquoise color, but it no longer has the spots, and it appears more rough and scaly with bumps here and there. The former bulb on its back has now fully bloomed into a gigantic flower and its ears have lightened up as well.
Female Venusaur are slightly different because they have a seed on their back, which shows that it can give birth to a new Bulbasaur.
