Bulbasaur

Bulbasaur is the Seed Pokémon. It is a Grass/Poison type Pokémon. It evolves into Ivysaur at level 16, which evolves into Venusaur at level 32. Bulbasaur, along with Charmander and Squirtle, is a starter Pokémon in Pokémon Red, Green, Blue, FireRed, and LeafGreen.

Biology
Bulbasaur resembles a baby dinosaur. It has three white claws growing out of its four legs. It has a green bulb on its back. Bulbasaur has green triangle-shaped designs all over its body. It's eyes are red with white scleroses. Bulbasaur has a purple mouth with a pink tongue, and two pointy white teeth sticking out of it's mouth. It is typically 2'4 feet tall, and weighs 15.2 pounds.

Bulbasaur means Schoenus Bulbus si lippus with can translate into The bulb-backed schoenus.

Bulbasaur is a small, quadrupedal Pokémon that has blue-green skin with darker patches. It has red eyes with white pupils, pointed, ear-like structures on top of its head, and a short, blunt snout with a wide mouth. A pair of small, pointed teeth are visible in the upper jaw when its mouth is open. Each of its thick legs ends with three sharp claws. On Bulbasaur's back is a green plant bulb, which is grown from a seed planted there at birth. The bulb provides it with energy through photosynthesis as well as from the nutrient-rich seeds contained within.

As mentioned in the anime, starter Pokémon are raised by Breeders to be distributed to new Trainers. Having been domesticated from birth, Bulbasaur is regarded as both a rare and well-behaved Pokémon. It is known to be extremely loyal, even after long-term abandonment. Bulbasaur in the anime have demonstrated a nurturing instinct towards younger, weaker Pokémon, one individual even using its vines to pick up a crying Pokémon, gently rocking it back and forth through the air while singing a "Bulba-by."

It is found in grasslands and forests throughout the Kanto region. However, due to Bulbasaur's status as starter Pokémon, it is hard to come by in the wild and generally found under the ownership of a Trainer. It has been observed that a Bulbasaur's bulb will flash blue when it is ready to evolve. If it does not want to evolve, it struggles to resist the transformation. Many Bulbasaur gather every year in a hidden garden in Kanto to evolve into Ivysaur in a ceremony led by a Venusaur.

Main series
Bulbasaur in the anime

Ash's Bulbasaur
Ash's Bulbasaur debuted in Bulbasaur and the Hidden Village as one of the Pokémon in the Hidden Village, thus also marking the species' physical debut. Though initially wary of Ash, the two eventually warmed up to one another, and Bulbasaur challenged him to a battle. Using Pikachu, Ash won the battle, and Bulbasaur was caught. Unlike Charmander and Squirtle, which were caught in the two episodes following that of Bulbasaur, Bulbasaur remained in Ash's party for most of his journey through Johto until Bulbasaur... the Ambassador!, when Ash sent him to Professor Oak's lab to work as an ambassador between otherwise argumentative groups of Pokémon.

May's Bulbasaur
Much later on, while Ash was traveling in the Hoenn region, May caught her own Bulbasaur after being separated from the group in Grass Hysteria!. She remained with her throughout the rest of her journey in Hoenn, helping her to win the Purika Contest and place Top 8 in the regional Grand Festival. When she traveled to Kanto to continue her journey with Ash in The Right Place and the Right Mime, May, too, left her Bulbasaur at Professor Oak's Laboratory to learn from Ash's while she, Ash, Max, and Brock traveled throughout the Kanto region. May retrieved her during her travels in Johto, where she evolved all the way into a Venusaur.
