Victreebel is a pitcher plant Pokémon with a bell-shaped body. It has a gaping mouth with pink lips and two sharp teeth. Its semicircular eyes appear directly under its mouth and it has several dark green spots on its body. On either side of its body is a large green leaf. Covering Victreebel's mouth is a leaf with a long, brown, yellow-tipped vine growing out of it. The vine is flicked to mimic an animal in order to attract prey. Victreebel also produces a sweet scent to further aid in luring its victims. Acid that has dissolved numerous prey animals becomes sweeter and even more effective at attracting prey.
It can be found in small groups and is territorial. In the manga, Victreebel hoards food, usually small birds and rodents, and collects Leaf Stones to perform evolution rituals at night to help Weepinbell become more Victreebel. Being the result of an evolution via Evolution stone, Victreebel is rarely found in the wild, though they can be found in temperate forests and jungles.
James had two separate Victreebel (traded for each other in Here's Lookin' at You, Elekid), both of which evolved from Weepinbell while in his possession. His second Victreebel was expelled from the group by Jessie after it attacked her. It landed near James's first Victreebel, both Pokémon fell instantly in love, and they hopped off together into the forest.
