The title's bosses have refreshed once again, bringing back Mega Venusaur raids in Pokemon GO. Unsurprisingly, trainers are flocking to gyms to defeat this Grass/Poison-type Mega Evolution and collect its energy for their own use.
Beating Mega Venusaur not only bestows Pokemon GO players with Mega Energy but also gives them the opportunity to catch a fully-evolved Venusaur.
If trainers are lucky, they can even catch a Venusaur with 100% perfect IV stats. It's then possible to use the acquired Mega Energy to Mega Evolve Venusaur, turning it into an incredibly powerful fighter, at least until the temporary evolution subsides.
Mega Venusaur raids in Pokemon GO will be active between Tuesday, September 2, 2025, at 10 am local time to Tuesday, September 9, 2025, at 10 am local time.
