>>20181688Yes, Venusaur is a Grass-type, meaning it is weak to Fire-type attacks. As you may or may not know, Grass-type Pokémon are also weak to Ice, Poison, Flying, and Bug attacks. Not all of these weaknesses hold for Venusaur, though, as it is also a Poison-type. To complicate matters further, its Mega has the ability Thick Fat, which neutralises its weakness to Fire and Ice.
