Most players write Beedrill off the moment Weedle hatches — it’s a first-route Bug with a 395 base stat total and a reputation as filler. That reputation is wrong on two counts. Beedrill finishes its entire evolution line faster than almost anything else in the game, and with a Mega Stone that’s currently locked behind one specific fight in Pokemon Legends Z-A, it becomes a 150-Attack, 145-Speed outlier that’s quietly running a near-identical, battle-tested build in Pokemon Champions VGC right now.
This guide covers all three layers: the level-10 evolution line every player deals with, the Mega Beedrill stat jump and why Adaptability makes it hit harder than the numbers suggest, exactly where to get Beedrillite, and the specific moveset players who actually run Mega Beedrill converge on. New to competitive Pokemon Champions entirely? Start with our Pokemon Champions beginner’s guide first.
Quick Start: Getting a Battle-Ready Beedrill
- Catch or hatch a Weedle — it evolves into Kakuna at level 7 automatically, no item or trade needed.
- Level Kakuna to 10. It can’t do much in a fight (Harden is its only level-up move), so push it there with Rare Candies, an Exp. Share, or a Lucky Egg pass rather than grinding battles with it directly.
- Decide if you want the Mega line: if you don’t own Pokemon Legends Z-A or can’t get a Beedrillite-holding Beedrill via Pokemon HOME transfer, stop here — base Beedrill is a fine early-game Bug answer on its own.
- If you do want Mega Beedrill, clear Main Mission 16 in Legends Z-A to fight Rogue Mega Beedrill and claim its Beedrillite [5].
- Hold Beedrillite on your Beedrill, teach it Poison Jab, Protect, U-turn, and Drill Run, and give it a Jolly nature if you’re breeding fresh — that’s the build the entire Pokemon Champions competitive scene has already converged on [4].
Fully Evolved by Level 10: The Weedle-to-Beedrill Timeline
Weedle evolves into Kakuna at level 7. Kakuna evolves into Beedrill at level 10 [1]. That’s the entire line — three levels between each stage, and a fully evolved Pokemon before most starters have even changed form once. The catch is the middle stage: Kakuna’s only level-up move is Harden, a Defense-boosting move with zero offensive value, so those three levels are functionally dead weight you have to push through with outside experience rather than let Kakuna fight for itself.
Once it evolves, Beedrill settles at a 395 base stat total — 65 HP, 90 Attack, 40 Defense, 45 Special Attack, 80 Special Defense, 75 Speed [1]. Its ability is Swarm, which boosts Bug-type moves by 50% once Beedrill drops below a third of its max HP, or the hidden ability Sniper, which raises critical-hit damage from the standard 1.5x multiplier to 2.25x whenever a hit crits [1]. Neither ability matters much for what Beedrill is actually built to do — that comes with the Mega Stone.
Mega Beedrill: 90 to 150 Attack, and the Ability Swap That Actually Matters
Mega Evolving pushes Beedrill’s stat total from 395 to 495, and almost the entire 100-point gain goes into two stats: Attack jumps from 90 to 150, and Speed jumps from 75 to 145 [1]. Special Attack, meanwhile, actually drops — from 45 down to 15. Game Freak isn’t trying to make a balanced upgrade here; Mega Beedrill is built as a pure physical glass cannon, and the numbers commit to that identity all the way, sacrificing a stat it was never going to use to maximize the two it will.
145 Speed alone would make Mega Beedrill fast. What makes it hit as hard as it does is the ability swap: Mega Evolving replaces Swarm or Sniper with Adaptability, which raises Beedrill’s same-type attack bonus (STAB) from the standard 1.5x multiplier to a flat 2x on any Bug- or Poison-type move [1]. That’s a bigger jump than the number implies — an 80-power move like Poison Jab normally hits with 120 effective power under regular STAB; under Adaptability it hits with 160. Nothing else about the move changes. The damage increase comes purely from Beedrill’s own typing matching the move, which is exactly why Beedrill’s whole competitive build is built around Bug- and Poison-type attacks instead of coverage moves that skip the bonus entirely.
How to Actually Get Beedrillite (Legends Z-A Is the Only Way Right Now)
If you own Pokemon Legends Z-A, the path is direct: Beedrillite drops from defeating Rogue Mega Beedrill during Main Mission 16, a fight that takes place on a rooftop in the Vert District east of Café Classe [5]. Rogue Mega Beedrill attacks with Poison Jab and Lunge, periodically charges into a barrage of auto-targeted Pin Missiles, and summons waves of Kakuna and regular Beedrill as the fight drags on [5]. Its Bug/Poison typing is weak to exactly four attack types — Fire, Flying, Rock, and Psychic — so Charizard, Aerodactyl, or Camerupt all cover it cleanly [5]. You can only hold one Antidote-worthy grudge against this fight: Beedrillite is capped at one per save file, so whichever Beedrill you give it to is the one you’re committing to [5]. That’s not a permanent decision, though — held items move freely between your own Pokemon any time you’re not locked into a set team, so if you hand it to the wrong Beedrill first, just take it back.
If you don’t own Legends Z-A, your only route is Pokemon HOME: transfer in a Beedrill that already holds Beedrillite from a save that cleared the Z-A fight. The stone itself has no other confirmed source as of Pokemon Champions’ current Regulation M-B, which runs through September 2, 2026 [2]. If neither option is available to you, Mega Beedrill isn’t currently reachable — base Beedrill still functions fine without it.
The Adaptability Set: What Actually Wins With Mega Beedrill in Champions
Mega Beedrill is not a popular pick in Pokemon Champions VGC — it sits around rank #162 in monthly usage, a small enough share that it barely registers against the format’s top threats [4]. That’s not the same as being weak. It reflects a real building problem: 40 Defense means Mega Beedrill cannot afford to take a hit from almost anything, so most teams pass on it rather than solve for it. The players who do run it, though, converge on almost the exact same set, which is a stronger signal of a build actually working than raw pick rate is [4].
Among teams using Mega Beedrill, Poison Jab appears in 98.2% of sets, Protect in 84.5%, U-turn in 78.6%, and Drill Run in 34.0%, with Knock Off as the next most common alternative at 25.6% [4]. Beedrillite and Adaptability are effectively universal at 100% each, since there’s no reason to run Mega Beedrill without either [4].
| Move | Usage | Why it’s on the set |
|---|---|---|
| Poison Jab | 98.2% | Adaptability-boosted Poison STAB, the primary damage source |
| Protect | 84.5% | Buys the turn Mega Evolving costs, since Beedrill can’t tank a hit while transforming |
| U-turn | 78.6% | Adaptability-boosted Bug STAB that pivots Beedrill out before a check punishes its 40 Defense |
| Drill Run | 34.0% | Coverage against Pokemon that resist both Bug and Poison |
| Knock Off | 25.6% | Strips items from switch-ins, unboosted but still useful utility |
Drill Run and Knock Off don’t benefit from Adaptability at all — the ability only boosts moves that share Beedrill’s own Bug or Poison typing, so Ground- and Dark-type attacks hit at their normal, un-multiplied power [1]. They’re on the set for coverage and utility, not damage, which is exactly why Poison Jab and U-turn take priority whenever a Bug or Poison-type answer isn’t the immediate threat.
Champions replaced the traditional EV/IV system with a points-based SP allocation model — if you’re not familiar with how that changes stat-building, read our SP System explainer before building this set. For Mega Beedrill, the priority is simple: max Speed to keep the 145 base stat ahead of as much of the field as possible, then max Attack for Poison Jab and U-turn damage, with a Jolly nature to protect that Speed lead. Common teammates include Incineroar and Pelipper — both fit the general pattern of redirection and priority support that lets a fragile, 40-Defense sweeper find a safe turn to Mega Evolve into [4].

Should You Actually Build This? By Player Type
| Player type | What to do |
|---|---|
| New player | Just let Weedle evolve naturally through levels 7 and 10. Base Beedrill is a serviceable early Bug-type without ever touching Mega Evolution. |
| Casual player | Don’t chase the Legends Z-A boss fight unless you already own the game — base Beedrill gets outclassed by better early Bug-types in most other titles, and the detour isn’t worth it for casual play. |
| Hardcore optimizer | Clear the Rogue Mega Beedrill fight the moment you reach it. A 2x-STAB ability paired with 145 base Speed is rare enough that Adaptability is worth the one-save-only commitment. |
| Completionist | Note the exact location (Vert District rooftop, Main Mission 16) and the one-per-save cap before you start — there’s no second chance to re-farm Beedrillite if you give it to the wrong Beedrill and don’t realize items can be moved back off. |
Frequently Asked Questions
Is Mega Beedrill actually good in Pokemon Champions, or is it a meme pick?
Neither, really — it’s a specialist. The low overall usage rank comes from how hard it is to build around, not from weak stats: 40 Defense punishes any team that can’t guarantee it a safe Mega Evolution turn. But the near-universal Poison Jab/Protect/U-turn/Drill Run set among the players who do run it shows the build itself works when the team around it is built correctly. Treat it as a high-ceiling pick for a team with redirection support, not a default slot.
Does Adaptability boost Drill Run and Knock Off too?
No. Adaptability only doubles STAB on moves that match Beedrill’s own Bug or Poison typing. Drill Run (Ground) and Knock Off (Dark) hit at completely normal power — they’re on the set purely for coverage against Pokemon that resist Beedrill’s main attacks, not for extra damage.
Why isn’t Beedrill weak to Ground, if Poison-types usually are?
Poison-type Pokemon take double damage from Ground-type attacks on their own, but Bug-type resists Ground by half — and those two multipliers cancel out exactly, leaving Bug/Poison Beedrill at neutral damage from Ground instead of weak to it. Its only four weaknesses are Fire, Flying, Rock, and Psychic.
Can I get Mega Beedrill without playing Legends Z-A?
Only through Pokemon HOME, by transferring in a Beedrill that already holds Beedrillite from someone else’s save. The stone has no other confirmed source under the current Regulation M-B ruleset [2]. If that’s not an option, Mega Beedrill isn’t reachable for you right now — stick with base Beedrill.
Key Takeaways
Beedrill’s real story isn’t the early-route reputation — it’s a Pokemon that finishes evolving faster than almost anything else in the game, then gets a Mega Evolution that turns a forgettable 90 Attack into a 150-Attack, 145-Speed outlier once Adaptability is in play. If you own Legends Z-A, the Rogue Mega Beedrill fight in Main Mission 16 is worth clearing early since Beedrillite is capped at one per save. Once you have it, the build is settled: Poison Jab, Protect, U-turn, and Drill Run with a Jolly nature is the set the Pokemon Champions competitive scene has already converged on — don’t overthink the moveset, just get the stone.
