Beedrillite is a special Mega Stone that allows the Pokémon Beedrill to undergo Mega Evolution during battles. When Beedrillite is used, Beedrill transforms into Mega Beedrill, gaining enhanced abilities and a new appearance. This transformation boosts its Attack and Speed stats, making it a formidable opponent in competitive play. To use Beedrillite, a trainer must have a Beedrill that is at least level 36 and must also possess the Mega Ring. Once these conditions are met, the trainer can activate Mega Evolution during their turn in battle, allowing Mega Beedrill to unleash powerful moves and strategies.
