How to Unlock Mega Victreebel in Pokémon Legends: Z-A
Pokémon Legends: Z-A brings a fresh wave of excitement with the return of Mega Evolution, including a lineup of brand-new forms for classic Pokémon. One of the most intriguing additions is Mega Victreebel, a formidable version of the Flycatcher Pokémon from the Kanto region. Unlike many other Mega Evolutions, unlocking this one requires you to prove your strength against it in a challenging battle.
This guide will provide a comprehensive walkthrough on how to unlock Mega Victreebel in Pokémon Legends: Z-A, covering how to get a Victreebel, how to defeat its Rogue Mega form, and how to use its exclusive Mega Stone.
How to Obtain Victreebel

Before you can unlock its Mega Evolution, you first need a Victreebel on your team. Victreebel is the final form of Bellsprout and is a Grass/Poison-type Pokémon.
- Catch Bellsprout or Weepinbell: The evolutionary line starts with Bellsprout, which can be found in lush, green areas like forests and swamps. After catching a Bellsprout, you can evolve it into Weepinbell by raising it to Level 21.
- Evolve Weepinbell into Victreebel: To evolve Weepinbell into Victreebel, you must use a Leaf Stone. This evolution item can be found throughout Lumiose City in a few ways:
-
- Mining glowing green ore deposits in caves or forest biomes.
- Receiving them as rewards for completing certain research tasks for Mable.
- Purchasing them from in-game shops or exchange posts.
Once you have a Weepinbell and a Leaf Stone, simply open your satchel, select the stone, and use it on Weepinbell to trigger the evolution.
How to Defeat Rogue Mega Victreebel
The key to unlocking Mega Victreebel is to defeat it in a Rogue Mega Pokémon battle. This encounter takes place during Main Mission 13.
Mission Location and Preparation
You will find the Rogue Mega Victreebel in Magenta Sector 9, where your ally Naveen will be waiting. As you approach, a cutscene will trigger, and the battle will begin.
Before heading into this fight, it’s wise to prepare. Stock up on healing items, especially Super Potions, Revive Potions, and Poison Potions, as Mega Victreebel relies heavily on poison-based attacks.
Recommended Pokémon
Rogue Mega Victreebel is a Grass/Poison-type, which makes it weak to Fire, Ice, Psychic, and Flying-type attacks. It is resistant to Water, Grass, Fighting, Fairy, and Electric-type moves.
One of the best Pokémon to bring to this battle is Camerupt. By this point in the story, you should have already defeated Rogue Mega Camerupt in Mission 12 and received its Mega Stone, Camerupite. A Mega-Evolved Camerupt can deal massive Fire-type damage, making it an ideal counter.
Battle Strategy and Attack Patterns
The fight against Rogue Mega Victreebel is a dynamic, action-based battle. You’ll need to dodge its attacks while commanding your own Pokémon. Here are the attacks to watch out for:
- Bullet Seed: Victreebel fires slow-moving seed projectiles. You can easily dodge these by moving sideways and then counterattack.
- Vine Whip: When you get too close, it will unleash a powerful whip attack. Maintain a safe distance and watch for it to stretch slightly, which is your cue to dodge away.
- Poison Puddles: The most dangerous attack. It spits globules of poison that create lingering puddles on the ground. Avoid the initial impact zone and do not step in the puddles, as they will damage both you and your Pokémon.
Your strategy should be to wait for an opening after Victreebel attacks. After it uses Vine Whip or Poison Puddles, there is a brief window where you can safely command your Pokémon to strike.
Focus on collecting the Mega Power Orbs that appear in the arena to fill your Mega Meter. Once it’s full, Mega Evolve your Camerupt (or another powerful counter) to deal significantly increased damage. Continue collecting orbs to keep the Mega Evolution active.
Using the Victreebelite Mega Stone
Upon defeating the Rogue Mega Victreebel, you will be rewarded with its exclusive Mega Stone: Victreebelite. With this item, you can now Mega Evolve your own Victreebel in battle.
- Equip the Stone: Open your satchel and have your Victreebel hold the Victreebelite.
- Activate in Battle: During combat, fill the transformation meter by attacking or collecting orbs.
- Mega Evolve: When the meter is full, press the right thumbstick to transform your Victreebel into its powerful Mega form.
Mega Victreebel retains its Grass/Poison typing but receives a substantial boost to its stats, turning it into a formidable offensive threat capable of overwhelming opponents with powerful attacks. By conquering its Rogue form, you can add this impressive new Mega Evolution to your arsenal and unleash its full potential in your adventures through Lumiose City.
