Snivy first appeared as one of the Pokémon owned by Professor Juniper along with the other Unova Starters, Oshawott and Tepig. A hungry Tepig sees some Berries on a table and goes to eat them. Tepig's sloppy eating causes juices to fall on Snivy's back which it quickly washes off with his tail. Tepig causes more juice to fall on Snivy who attacks in anger and the two begin fighting. Oshawott, the more peaceful of the three, unsuccessfully tries to get them to stop and constantly gets hit in the process. Eventually, Oshawott reaches its boiling point and begins attacking Tepig and Snivy, forcing them to use any object in Professor Juniper's lab they could find to protect themselves. Professor Juniper comes in to find the three in their violent tussle and sends them back into their Poké Balls; the three sleep inside while Professor Juniper worriedly wonders if they are truly ready to be Pokémon for the upcoming Trainers.
Later, Snivy, along with Tepig and Oshawott, are sent to Black's home from the lab and the package reaches the boys hands. Black's cold, which he got after staying in the rain while waiting for package to come, causes him to sneeze and drop the box, releasing the Pokémon from their Poké Balls. Snivy and Tepig get into another fight and Oshawott once again tries to stop them only to get angry again and violently attack them. Tepig runs off with Black following, leaving Snivy at the mercy of Oshawott's rage. Later, Professor Juniper shockingly arrives to see the aftermath of the battle between Snivy and Oshawott. Next, Bianca and Cheren arrive wondering what had happened; while Professor Juniper worries about her broken Pokédexes, Bianca hands Cheren Snivy, stating that it resembled him, and takes Oshawott for herself. After they find Black and witness him and Tepig defeating a wild attacking Sewaddle, Snivy just looks away uninterested while the others look in shock. Afterwards, Snivy is used against Bianca's Oshawott which ends with the latter and its Trainer attacking Cheren and Snivy in anger.
After Cheren and Bianca arrive in Striaton City to tell Black to take care of his Pokédex, they get roped into his Gym battle. Snivy, along with Oshawott and Tepig, now named Tep, are used to battle the Gym Leaders, Cilan, Chili, and Cress. Before doing so, Snivy is used to teach Bianca about Pokémon type compatibility by having it and Tep attack her Oshawott and teach Bianca which types are strong and weak against Water-type Pokémon. After passing through the Gyms challenge, they face the Gym Leaders.
At first, Snivy and the others are overpowered by the three Pokémon belonging to the Gym Leaders but eventually gain the upper hand when they use teamwork. Snivy was defeated by Chili's Pansear after it made itself stronger with Work Up. Luckily, Tep managed to grab some of Pansage's leaves and feeds them to Snivy and Oshawott, rejuvenating them. Just as they are revived, the match's time limit ends, allowing Cheren, Bianca, and Black to win with 3-2.
In Driftveil City, Cheren was attacked by two Team Plasma Grunts and had Snivy taken from him. With the help of Black and his newly evolved Tranquill, Cheren managed to free Snivy from its captors. Together, with Black's Nite, Snivy defeated the Grunt's Pokémon with a Grass Pledge and Fire Pledge combination.
In the Unova Pokémon League, Snivy was used to battle the Hood Man's Klink after substituting it with his Boldore. Much to Black's confusion, Snivy had yet to evolve despite it being Cheren's first Pokémon. During the battle, Snivy was clearly outmatched, which disappointed Cheren. Cheren forcibly switched Snivy out with Unfezant, who defeated the Hood Man and allowed Cheren to advance to the finals. Seeing how badly he treated his Snivy makes Black furious enough to challenge his friend in battle immediately.
Snivy reappeared in the Black 2 & White 2 chapter, where he was used to keep Hugh quiet after his loud talking kept disrupting the class Cheren was teaching.
Personality and characteristics
Snivy, like its species, is a proud and arrogant Pokémon. Snivy is shown to hate getting dirty and will instantly try to clean himself off. If whoever got him dirty in the first place continues doing so, Snivy will attack in retaliation. According to Bianca, Snivy and Cheren resemble each other.
