Venusaur is a squat, quadrupedal amphibianPokémon with bumpy, blue-green skin. It has small, circular red eyes and a short, blunt snout. Its mouth is wide with two pointed teeth in the upper jaw and four in the lower jaw. On top of its head are small, pointed ears with reddish pink insides. It has three clawed toes on each foot. The bud on its back has bloomed into a large pink, white-spotted flower. The flower is supported by a thick, brown trunk surrounded by green fronds. A female Venusaur has a seed in the center of its flower.
Venusaur uses its flower to catch the sun's rays to convert them into energy, which causes the flower to become more vibrant. The flower releases a soothing scent that attracts Pokémon and calms emotions. This scent becomes stronger after a rainy day. In the anime, Venusaur has demonstrated the ability to manipulate nature, release several vines from its back, and lead evolution ceremonies for Bulbasaur and Ivysaur. This Pokémon is rarely found in the wild, but it has been known to inhabit grasslands.
As Mega Venusaur, the flower on its back grows larger and two smaller pink flowers bloom, one on its forehead and one on its rear. Its legs and back have become sturdier to support the extra weight of the flower. Additional leaves with woody stems, which are supported by vines, are also grown around the flower. Mega Venusaur also develops dark markings on its forehead below the new flower on its forehead.
As Gigantamax Venusaur, it becomes larger with its flower blooming even further, to the point of covering its body. These flowers have a taller bud, along with extremely thick and springy petals that are capable of shielding Gigantamax Venusaur. Its eyes have light green sclerae and orange irises. More foliage grows from under its flower, and the trunk that supports said flower becomes shorter. It has several light green markings located at its belly.
Gigantamax Venusaur attacks with its thick vines, which are powerful enough to topple down a 10-story building. Gigantamax Venusaur's flower can spread enough pollen in a similar fashion to a volcanic eruption. Breathing in this pollen can cause uncontrollable sneezing, and inhaling large amounts can even cause fainting. However, this pollen also promotes plant growth in areas where it lands.
A Venusaur nicknamed Bruteroot appeared in Mewtwo Strikes Back and its remake Mewtwo Strikes Back—Evolution, under the ownership of Corey. It was taken away from her by one of Mewtwo's special Poké Balls but was liberated by Ash along with the other confiscated Pokémon. Along with Ash's Charizard and Neesha's Blastoise, they were the only confiscated Pokémon not to be cloned and they had the same marks that Bulbasaurtwo had, indicating that it was likely obtained by Mewtwo through different means than the ones used to clone. Its clone reappeared in Mewtwo Returns. Corey's Venusaur also appeared in an alternate timeline of the main series that was introduced in I Choose You!, where it was seen battling Neesha's Blastoise; it is unknown if it holds the same nickname in that timeline.
In Ivysaur's Mysterious Tower!, multiple Venusaur evolved from Ivysaur after they traveled to a new Gym, which was under construction in Vermilion City, so they could absorb the sunlight needed for the evolution process.
Venusaur, the Seed Pokémon. A Grass and Poison type. It's believed that a nutritious diet and lots of sunlight make Venusaur's flower bloom in more vibrant colors. The flower's scent can calm and heal the human heart.
In I'm Your Venusaur, a local legend states that a 300-year-old tree, the Venusaur Tree, was grown out of a Venusaur who protected the town from invaders many years ago. The Venusaur and its tree are considered the guardians of the town.
A Venusaur appeared in a fantasy along with the other fully evolved Kanto starters in Chinchou in Charge, where the Pokémon Association Chairman of Kanto and Johto explains to Bill and Janine the special privilege of entering the finals unconditionally after collecting the badges.
When Venusaur is released from a Poké Ball, it uses the move Earthquake, which acts similarly to Donkey Kong's Down + B attack. Any player caught in this will be sent flying.
Venusaur is also a Pokéfloat. The front half will push itself onto the screen first and play will then begin to move to the right after Snorlax leaves the screen.
Evolving from Ivysaur, this deceptively toxic Pokémon has a huge flower on its back that emits a cloying fragrance: the scent lulls its enemies into a state of calmness. Venusaur's flower synthesizes sunshine into pure energy for its SolarBeam move. Think of Grass-type Pokémon, and Venusaur comes first.
Mega Venusaur appears as a trophy in both versions of the game.
With a special type of Mega Stone called Venusaurite, Venusaur can Mega Evolve into Mega Venusaur in the middle of a battle. Not only does Venusaur get a large defense boost when it Mega Evolves, but the plants on its back grow so much, it looks like you're being attacked by a walking jungle. Now, that's got to be intimidating!
According to Ken Sugimori in a Japanese interview discussing the Pokémon franchise, Venusaur and its pre-evolutions were inspired by frogs. In particular, its short legs, stout appearance, ear-like protrusions on its head, and the Thick Fat Ability on Mega Venusaur, together make it resemble horned frogs. Unlike Bulbasaur, Venusaur's "ears" have hollows, indicating that they are in fact ears and not glands, as seen in many species of frogs and toads. It also shares similarities with the extinct Pareiasaur.
