Bulbasaur

A strange seed is planted on Bulbasaur's back at birth which sprouts into a plant. The toad-esque Bulbasaur makes up for lack of size with a will of iron—especially trained by someone like Ash. This Pokemon's confidence and ensnaring vine abilities make it a powerful ally. In "Bulbasaur and the Hidden Village," Ash finds Bulbasaur to be very tough and extremely difficult to capture in the wild—but Ash finally captures it with great persistence.
