Carnivine (the Bug Catcher Pokémon) is a relatively rare Grass-type Pokémon found among forests and jungle environments within the Unova and Kalos regions, many parts of Africa and the Kanto and Johto regions on rare occasions. Though perhaps not as strikingly fearsome as other Grass-type fighters, Carnivine are vicious beasts that will gladly take apart their opponents piece by piece even if it means putting themselves in danger in the process. They might not have much to offer professional fighters in the way of move variety or even stats, but if you need a Grass-type that can bite its way through the opposition and stay safe from a Ground-type assault, you won't find a better partner than these oversized flytraps!
Carnivine are strange plants believed to be closely related to the traditional Venus flytrap but take their relative's carnivorous tendencies to a new level of dominance and ferocity in the plant world. Unlike most plant-based Pokémon, Carnivine are not able to utilize special attacks very well and instead rely on their long, whip-like roots and razor-sharp leaves to deal damage from afar, particularly favoring Vine Whip and Power Whip attacks above all else. In close quarters, however, Carnivine will rarely ever resort to attacking with anything aside from their huge mouth, which is lined on the outside by razor-sharp edges that can cut through soft flesh fairly easily. Aside from making Carnivine the only biologically-pure plant-based organism capable of effectively utilizing Bite and Crunch attacks, this can prove to be an exceptional danger to unarmored opponents because of the sheer strength with which Carnivine can actually bite down, making them a decent threat in many intermediate-level battles. It is further noted that Carnivine are wholly unique among Grass-types in that they are the only species of their type that can naturally possess the Levitate Ability. It has debated for some time what the exact cause for this is, but it is now widely believed that Carnivine have naturally developed the ability to convert the bioelectric energy within their cells into an electromagnetic field that enables their frame to be lifted off of the ground enough to avoid Ground-type attacks, though this is likely just a consequence and was probably initially developed as a way of allowing them to more easily attack and devour more mobile prey in the wild.
Carnivine rarely ever walk on the ground and instead prefer to hang from tree branches, using their lower roots to bind their bodies to tree branches and hang upside-down. This is generally done because although they might be strong enough to deliver devastating Vine Whip and Power Whip attacks, these roots are fairly sensitive and can only walk on soft, muddy ground without making Carnivine at least somewhat uncomfortable. While hanging upside-down, Carnivine release a sweet scent from the inside of their mouths (which can be opened an entire 180 degrees without tearing any connective tissue) and simply wait for something to enter their mouths. To protect themselves against accidentally chomping down on a piece of debris or a leaf, Carnivine share with their flytrap relatives a series of fine sensory hairs on the inside of their mouths that are designed to alert Carnivine to the presence of an actual living creature; when enough of these sensory hairs are triggered, it activates an involuntary muscle reflex that causes Carnivine to bite down hard, severely injuring or even squashing their prey in a single strike. Once their prey has been killed either by the initial strike or through additional biting attacks, Carnivine release a powerful digestive enzyme into their mouth and let it dissolve their meal slowly. It takes Carnivine an entire day to digest and process a single meal, but once they are finished, they merely spit out the indigestible hard body parts (exoskeleton pieces and bone) before perching once again and continuing their hunting spree.
While they might not have much to offer the traditional Grass-type specialist, Carnivine are interesting beasts that can certainly fight back with decent force in close-quarters brawls. Their immunity to Ground-type attacks may not offer much trainers in the way of a tactical advantage, but for those willing to bet on their vicious biting and whipping attacks for power, they can certainly prove to be more resourceful than their moves might otherwise suggest. Just be careful about feeding them and try not to make yourself a handy target when they haven't eaten in a while; Carnivine might not be terribly brutal, but they also won't think twice about taking a bite out of you if they feel hungry!
