If you’re playing Pokémon Legends: Z-A and you’re eager to obtain the Mega Evolution variant of Beedrill (known as Mega Beedrill), then you’re in the right place. In this article, I’ll walk you through exactly how to reach and defeat the Rogue Mega Beedrill, get the Mega Stone (Beedrillite), and start using Mega Beedrill. This guide uses accessible language, varies sentence length, and is easy to follow while still being geared for players ready for an advanced step.

Before you can reach Mega Beedrill, you’ll need to have progressed through the main story to a certain point. The game introduces the Rogue Mega Pokémon mechanic — powerful wild versions of Mega-eligible species. To unlock the fight against Rogue Mega Beedrill, you must clear the main mission that triggers this encounter.
In short:
- Progress to Main Mission 16 (or the mission that names Rogue Mega Beedrill) in the story.
- Make sure you have access to fast travel in the area and are comfortable battling strong opponents.
- Finish any side tasks that might block access to the rooftop battle area.
Where to go to trigger the battle
The specific encounter location for Rogue Mega Beedrill is in the Vert District of Lumiose City. Here’s how you can reach it:
- Fast travel to the Poké Centre near Café Classe (or a similar nearby landmark).
- Take the elevator up to the rooftop of the building just east of Café Classe.
- From there, follow the rooftop path toward the scaffolding and use the Roto-Glide tool to move between buildings until you reach the platform where the Rogue Mega Beedrill awaits.
- The mission unlocks as part of the main story — look for the mission title referencing “Rogue Mega Beedrill.”
It’s important not to rush this part. Take a moment to heal up, ensure your team is in good shape, and stock up on Antidotes, as Beedrill uses several strong Poison-type attacks.
How to defeat Rogue Mega Beedrill
This battle is tougher than most regular wild encounters. Rogue Mega Beedrill is a Bug/Poison-type, and it comes with several nasty attacks. Here are the key tips to win efficiently:
Type weaknesses and counters
- Weak to: Fire, Flying, Psychic, and Rock types.
- Resists: Bug, Fairy, Fighting, Grass, and Poison attacks — avoid relying on these.
Recommended counters:
- A strong Fire/Flying type like Charizard.
- A Rock/Flying type like Aerodactyl.
- A Psychic type with good defense, such as Alakazam, to take advantage of Beedrill’s Poison weakness.
Battle mechanics to watch
- At the start of the fight, smaller Kakuna minions spawn. Later, more Beedrill may join the field. Clear them quickly to avoid being overwhelmed.
- Rogue Mega Beedrill occasionally enters charge mode, where it flies up and then unleashes a barrage of large Pin Missiles. Be ready to dodge or retreat your Pokémon during this phase.
- Its Lunge attack allows it to teleport close and strike rapidly — timing your dodge or defensive move is crucial.
- The Poison status is a constant threat. Bring Antidotes or use Pokémon resistant or immune to Poison-type moves.
Suggested strategy
- Start the fight by eliminating the smaller enemies first. This makes focusing on the main boss much easier.
- Lead with your strongest Fire or Flying type, but switch out if you’re taking heavy damage.
- When Beedrill charges its missile barrage, pull back or dodge to avoid losing key team members.
- Use your most powerful moves strategically — save them for when Beedrill’s defenses drop or after dodging its major attacks.
- Maintain patience. This battle rewards consistency and timing over brute force.
Claiming the Mega Stone (Beedrillite)
Once you’ve defeated Rogue Mega Beedrill, you’ll receive the Beedrillite, the Mega Stone required to evolve your own Beedrill into Mega Beedrill. This unlocks the ability to use one of the most agile and high-damage Mega Evolutions in the game.
Steps to use it:
- Ensure you already have a Beedrill in your party, or have evolved a Kakuna into Beedrill.
- Go to your Bag and equip the Beedrillite to Beedrill.
- In battle, build up your Mega Power gauge (by attacking or collecting dropped orbs), then activate Mega Evolution when ready.
- After Mega Evolving, Beedrill’s stats skyrocket, especially its Speed and Attack, and it may gain an upgraded “+” version of one of its moves. Use this boosted phase to overwhelm opponents.
