Metang is often regarded as one of the most iconic mid-stage evolutions in the Pokémon world. As a dual-type Steel/Psychic Pokémon introduced in Generation III, it serves as the bridge between the simple Beldum and the pseudo-legendary powerhouse, Metagross. For trainers looking to optimize their team, understanding the specific metang evolution level and the mechanics behind its growth is essential for long-term success.

The core numbers: When does Metang evolve?

The evolution process for this line is strictly level-based, requiring no special stones, friendship mechanics, or trade requirements. This makes the progression predictable but demands a significant amount of experience points due to its "Slow" leveling rate.

  1. Beldum to Metang: Beldum evolves into Metang starting at Level 20.
  2. Metang to Metagross: Metang evolves into Metagross starting at Level 45.

Reaching Level 45 can feel like a grind in the mid-game of most regional journeys. Unlike many other three-stage evolution lines where the second stage is reached around Level 16-18 and the final stage at Level 32-36, the Metagross line follows the high-threshold pattern typical of pseudo-legendaries like Dragonite or Tyranitar. This reflects its immense power and the biological complexity described in its lore.

Biological lore and the fusion mechanic

One of the most fascinating aspects of Metang is its biological origin. According to various Pokédex entries across generations, Metang is not just a grown-up version of Beldum; it is literally the result of two Beldum fusing together. This magnetic fusion creates a shared nervous system, linking two brains to increase psychic prowess.

When Metang reaches Level 45, the process repeats on a larger scale. Two Metang (which technically contain four Beldum) combine to form a single Metagross. This lore explains why Metagross has four brains and four metallic claws. While the games do not require you to have two Metang in your party to evolve one, the level 45 requirement serves as the mechanical representation of this complex structural integration. It is a transformation that signifies the perfection of its magnetic and crystalline form.

Analyzing Metang’s stats: More than just a transition

Many trainers view mid-stage Pokémon as temporary placeholders, but Metang possesses a defensive profile that demands respect. With a Base Stat Total (BST) of 420, it is significantly sturdier than most mid-evolutions.

  • HP: 60
  • Attack: 75
  • Defense: 100
  • Special Attack: 55
  • Special Defense: 80
  • Speed: 50
  • Total: 420

The standout stat here is the Base 100 Defense. When combined with the Steel typing—which provides resistances to a massive array of types including Normal, Grass, Ice, Flying, Psychic, Bug, Rock, Dragon, and Steel, as well as an immunity to Poison—Metang becomes a formidable wall even before it reaches its final form.

The Eviolite strategy: Is it worth delaying evolution?

A common question among competitive players is whether to keep Metang in its current state using an Eviolite. This held item boosts the Defense and Special Defense of a Pokémon that is not yet fully evolved by 50%.

With an Eviolite, Metang’s effective Defense climbs to a staggering level, often surpassing the raw defensive stats of a fully evolved Metagross. Some players use this setup in specific formats (like Middle Cup or certain restricted tiers) to create a psychic tank that is nearly impossible to one-shot without a powerful super-effective Ground, Ghost, Fire, or Dark move.

However, for a standard playthrough or high-level competitive play, the loss of Metagross’s 135 Base Attack and its ability to Mega Evolve (in relevant formats) usually makes the Level 45 evolution the better choice. Metang’s lower offensive pressure means it can often be ignored or set up on by opponents, whereas Metagross is a proactive threat.

Key moves to learn during the leveling process

To make the journey to Level 45 easier, you need to manage Metang’s movepool effectively. Beldum is notoriously difficult to train because it only learns Take Down, a move that causes recoil damage and has shaky accuracy. Once it evolves at Level 20, Metang finally gains access to a more versatile toolkit.

Essential Level-Up Moves

  • Confusion (Level 1): Basic Psychic STAB (Same Type Attack Bonus) that helps early on.
  • Metal Claw (Level 1): A reliable Steel-type physical move that has a chance to boost Attack.
  • Zen Headbutt (Level 26): A powerful Physical Psychic move that can flinch opponents. This is a staple for Metang until it reaches its final form.
  • Flash Cannon (Level 32): Though Metang’s Special Attack is lower, this can be useful against physically defensive walls.
  • Psychic (Level 38): The classic Special Psychic move for coverage.
  • Meteor Mash (Level 44): Technically, in many generations, Metagross learns this immediately upon evolving at 45 or via a Move Relearner, but some versions allow Metang to pick it up late. This is the signature move of the line and essential for any build.

TM and Tutor Considerations

Metang has access to excellent coverage moves via TMs, such as Earthquake, Rock Slide, and Ice Punch. Giving Metang Earthquake early can significantly help it deal with the Fire and Steel types that otherwise resist its main attacks.

Training tips: Reaching Level 45 efficiently

Given the "Slow" experience group, Metang requires 1,250,000 EXP to reach Level 100, and a proportional chunk of that to reach Level 45. Here are some ways to expedite the process:

  1. The Lucky Egg: Always have Metang hold a Lucky Egg. This increases the experience gained in battle by 50%. In most modern games, you can obtain this from a biology teacher or a specific NPC after reaching a certain point in the story.
  2. Exp. Candies: In newer iterations like Scarlet and Violet, Raid Dens provide Exp. Candies. This is the fastest way to bypass the mid-40s grind. A few Large or Extra Large candies can instantly bridge the gap from Level 20 to 45.
  3. Type Advantage Hunting: Train in areas with many Fairy, Ice, or Rock-type Pokémon. Metang’s Steel typing allows it to resist their hits while dealing super-effective damage with Metal Claw or Bullet Punch (if available via Move Relearner).
  4. The Blueberry Academy (Gen IX): If you are playing the Indigo Disk DLC, the Canyon Biome is a prime spot for training against Pokémon that Metang can handle comfortably.

The challenge of catching Metang

If you aren't evolving a Beldum and instead try to catch a wild Metang, be prepared for a frustration similar to catching a Legendary. Metang has a Catch Rate of 3. For context, this is the lowest possible catch rate in the game, shared by the likes of Mewtwo and Arceus.

When attempting a wild catch, it is vital to:

  • Inflict Status: Sleep or Paralysis are the best options.
  • False Swipe: Reduce its HP to exactly 1. Be careful, as some wild Metang may know moves with recoil, though this is rarer than with Beldum.
  • Timer Balls: Since the battle will likely last many turns, Timer Balls become more effective than Ultra Balls after turn 10.

Competitive viability in the current meta

In the context of April 2026, Metagross remains a solid pick in various competitive tiers. However, the path through Metang is more than just a hurdle. In "Middle Cup" formats, Metang is a top-tier threat because of its typing and bulk.

For trainers in the main VGC (Video Game Championships) or Smogon formats, the transition to Metagross at Level 45 is non-negotiable. The current power creep in the game means that mid-stage Pokémon lack the raw speed and offensive output to keep up with the latest Paradox Pokémon or Legendary threats. The goal is to reach that Level 45 evolution as safely and quickly as possible to unlock the Clear Body ability’s full potential on a 600 BST frame.

Comparison with other Steel/Psychic types

Metang is often compared to other Steel/Psychic types like Bronzong or Jirachi. While Bronzong offers more utility with moves like Trick Room and the Levitate ability (which removes its Ground weakness), the Metang line is designed for physical aggression.

Bronzong evolves from Bronzor at Level 33, which is much earlier than Metagross’s Level 45. This makes Bronzong a more accessible mid-game option for casual playthroughs. However, the sheer ceiling of Metagross’s stats usually justifies the extra 12 levels of training required for Metang.

Decision making: When to stop?

Is there ever a reason not to evolve Metang at Level 45? For 99% of trainers, the answer is no. Once Metang hits that level, the increase in every single stat category is too significant to ignore. Metagross gains +20 HP, +60 Attack, +30 Defense, +40 Special Attack, +10 Special Defense, and +20 Speed over its predecessor.

The only niche reason to delay evolution would be to learn a specific move slightly earlier if a particular game's level-up set allows it, but even then, with the modern Move Relearner being accessible from the menu in most recent titles, this strategy is largely obsolete.

Conclusion

The journey of a Metang is one of patience and power. From its humble beginnings as a Beldum at Level 1 to its first major milestone at Level 20, and finally its ascension to Metagross at Level 45, this Pokémon represents the pinnacle of Steel-type engineering. Whether you are using it as an Eviolite tank in a restricted format or grinding through the wilderness to unlock its final form, Metang remains a cornerstone of the Pokémon experience. Keep your Lucky Eggs ready, mind your type matchups, and the transition to the Iron Claw Pokémon will be a rewarding one.
