Bulbasaur

Bulbine repens, known by it's common name, Bulbasaur, is a Grass/Poison type Pokemon native to the Kanto Region. It's a member of the Bulbine family, of which it is the infantile form.

Biology
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.

The Bulb on Bulbasaur's back is a large flowering plant that emits a stench in it's infantile form. This stench is used to deter predators from finding Bulbasaur when it's away from it's parents, though it seems to have little effect on humans. Bulbasaur's bulb is very high maintence, requiring a near constant stream of daily sunlight and water. However, if treated well, Bulbasaur's bulb will bloom into it's intermediate stage, and it will evolve.

Bulbasaur, being a grass type pokemon, makes it's own energy via photosynthesis. Using the dark spots on it's face, legs, and body, Bulbasaur converts sunlight to energy. However, unlike most grass type pokemon, it still requires sustenance, as the energy it makes is given to it's Bulb. It uses its sharp teeth to tear the edges of leaves and ferns, which it then eats. If you spot a lot of torn leaves on a low hanging tree, it's a telltale sign of a nearby family.

Behavior
Bulbasaur are naturally social creatures, especially when it comes to other Bulbasaur. Like most infant stage pokemon, Bulbasaur's naieviete is great, which pairs dangerously with it's lack of developed survival instincts. Bulbasaur are fun loving Pokemon, and will often play-fight with eachother for entertainment. However, due to their nature as grass type pokemon, no real damage occurs.
