Venusaur is considerably larger and heavier than both of its pre-evolutions are, and as such, it moves slower than the two when it is not in battle, though it retains its quadruped form. The bud on its back has since bloomed into a large red flower with six expansive, white-spotted petals, supported on a brown trunk somewhat like that of a palm tree. Instead of patches on its skin, Venusaur appears to have frog-like warts. Additionally, the insides of Venusaur's ears now appear to be red in coloration.
Venusaur is one of two Pokémon that shares no types with other main series version mascots. The other is Groudon.
