Meltan remains one of the most intriguing additions to the Pokémon universe, serving as a unique bridge between mobile gaming and console experiences. As a Steel-type Mythical Pokémon first discovered through the intersection of Pokémon GO and the Kanto region titles on Nintendo Switch, it holds the distinction of being the only Mythical Pokémon capable of evolution. This characteristic makes understanding the Let's GO Meltan mechanics essential for any trainer looking to complete their National Pokédex or dominate in high-level Master League battles.

The Biology of Meltan and Melmetal

Classified as the Hex Nut Pokémon, Meltan features a body primarily composed of liquid metal. This fluid structure allows it to corrode other metallic objects, absorbing them into its own mass to generate electricity. This internal energy serves both as its life force and as a weapon, which it can discharge through its single, centered eye.

When Meltan evolves into Melmetal, the physical transformation is drastic. After 3,000 years of absence, Melmetal re-emerged with a body that has hardened significantly, becoming one of the sturdiest Steel-types in existence. In ancient times, it was worshipped for its ability to create metal from nothing. Its signature move, Double Iron Bash, utilizes the hexagonal nuts on its arms as centrifugal axles to deliver a devastating two-hit strike that can cause opponents to flinch.

Let's GO Meltan Special Research Walkthrough

For many trainers, the primary method of encountering this Pokémon is through the nine-stage Special Research quest in Pokémon GO titled "Let's GO, Meltan." This questline is designed to test a trainer's fundamental skills across various gameplay mechanics.

Stages 1-3: Foundations and the Ditto Barrier

The initial stages focus on basic activities. Players are required to spin five PokéStops, catch ten Pokémon, and transfer five. These tasks award experience and essential items like Incubators. The difficulty increases in Stage 2, which requires walking with a buddy to earn two candies and making ten Great Throws.

Stage 3 presents the first significant hurdle: catching a Ditto. Because Ditto hides as other common species on the map, this task relies on persistence. During specific seasonal events, Ditto's disguise list is often updated, making it necessary to monitor which common spawns are currently eligible to be a transformed Ditto.

Stages 4-6: Typing and Evolution Trials

Stage 4 shifts focus to specific elemental types, requiring the capture of five Steel-type and five Electric-type Pokémon. This is a thematic nod to Meltan's own characteristics. Stage 5 involves evolving a Grimer and catching five Slugma or Gulpin.

Stage 6 is arguably the most time-consuming for casual players, as it requires evolving a Magnemite and participating in ten Raids. To optimize this, players can focus on Tier 1 raids which are soloable, ensuring progress without the need for a large group. The reward for this stage includes a Metal Coat, a necessary item for other Steel-type evolutions.

Stages 7-9: The Fossil Grind and Completion

Stage 7 requires evolving a Drowzee, catching a Cubone, and evolving a Scyther. Cubone can occasionally be difficult to find outside of specific biomes or events, so utilizing Daily Adventure Incense is a recommended strategy.

Stage 8 is the final challenge, requiring the capture of two Omanyte or Kabuto, two Lileep or Anorith, and one Aerodactyl. These fossil Pokémon are frequently available in 7km eggs or as rewards from specific "Win 5 Raids" field research tasks. Upon completing these, Stage 9 provides the encounter with Meltan along with a significant amount of Stardust and XP.

The Mystery Box: The Efficient Capture Method

While the Special Research provides a single Meltan, the most efficient way to gather enough resources for evolution is the Mystery Box. This item functions like a specialized Incense that exclusively attracts Meltan for a set duration (typically 60 minutes).

How to Obtain the Mystery Box via Pokémon HOME

In 2026, the most streamlined method to acquire the Mystery Box is through Pokémon HOME. Trainers do not need a Nintendo Switch to do this; the mobile version of HOME is sufficient.

  1. Link Accounts: Ensure the Pokémon GO account is linked to the same Nintendo Account used for Pokémon HOME.
  2. Transfer a Pokémon: Select a Pokémon in GO to send to HOME. Note that this is a one-way transfer.
  3. Activate the Box: Once the transfer is confirmed in the HOME app, the Mystery Box will appear in the Pokémon GO items bag.
  4. The Cooldown: After use, the box becomes inactive. Typically, a player must wait three days and perform another transfer to HOME to reactivate the box. During special event windows, this cooldown period may be reduced to 48 or even 24 hours.

Link with Pokémon: Let's Go, Pikachu! and Eevee!

For players who own a Nintendo Switch and the Let's Go series, the Mystery Box can also be obtained by reaching the GO Park Complex in Fuchsia City. Transferring any Kanto-region Pokémon from the mobile app to the Switch console will trigger the Mystery Box reward. This remains a reliable method for household members to share a single console to unlock boxes for multiple mobile accounts.

Evolving Meltan into Melmetal

Meltan's evolution is unique because it can only occur within Pokémon GO. It requires 400 Meltan Candies. While 400 seems daunting, a single Mystery Box session can yield between 50 to 100 candies if Pinap Berries are used effectively.

Strategic Tips for 400 Candies:

  • Pinap Berries: Always use a Pinap or Silver Pinap Berry for every Meltan encounter. This doubles the candy count per catch.
  • Mega Evolution Bonus: Having an active Level 3 Mega Evolution of a Steel-type Pokémon (such as Mega Aggron or Mega Steelix) provides a significant chance to receive extra Candy XL and additional regular candies per catch.
  • Transfer Events: Save excess Meltan to transfer during spotlight hours or events that offer 2x Transfer Candy.

Once evolved, Melmetal can be transferred back to the Nintendo Switch for use in games like Pokémon Sword/Shield or Scarlet/Violet, where it becomes a powerhouse in the competitive circuit.

Technical Statistics and Battle Viability

Understanding the numerical value of these Pokémon helps in deciding whether to invest Rare Candies or Stardust.

Meltan Stats

  • Type: Steel
  • Base HP: 46
  • Base Attack: 65
  • Base Defense: 65
  • Total Base Stats: 300

Meltan itself is generally not viable in competitive play, even in Little Cup formats, due to its limited move pool and low stats. Its primary purpose is evolution.

Melmetal Stats

  • Type: Steel
  • Base HP: 135
  • Base Attack: 143
  • Base Defense: 143
  • Total Base Stats: 600

Melmetal's stat distribution makes it a premier "tank" in Pokémon GO's Master League. Its pure Steel typing provides resistances to ten different types, including the prevalent Dragon, Fairy, and Psychic moves.

Optimal Move Sets

In Pokémon GO, the most effective move set for Melmetal generally includes Thunder Shock (Fast Move) for rapid energy generation, paired with Superpower and Double Iron Bash (Charged Moves). Superpower provides essential coverage against other Steel and Normal types, while Double Iron Bash offers STAB (Same Type Attack Bonus) and the potential to bait shields due to its speed.

Shiny Meltan Availability

Unlike most Pokémon, Shiny Meltan is time-locked. It cannot be encountered during normal gameplay or regular Mystery Box usage. The shiny form is only enabled during specific global events, usually once or twice a year.

In its shiny form, Meltan's hexagonal nut head takes on a darker, copper-like gold hue, and its tail is blue instead of red. Trainers interested in the shiny variant should conserve their Mystery Box usage when an event is announced to ensure they have the box ready to open the moment the event begins.

Integration with the 2026 Ecosystem

As the Pokémon franchise continues to evolve, the integration between mobile and cloud storage (HOME) has become the standard for maintaining a "Living Dex." Meltan represents the successful implementation of this cross-platform strategy. Whether acquired through the nostalgic Let's GO Meltan questline or the efficient Mystery Box method, Melmetal remains a staple in both collectors' boxes and competitive teams. The accessibility of the Mystery Box through Pokémon HOME ensures that new players in 2026 are not gated by the requirement of owning older hardware, maintaining Meltan's status as a globally attainable Mythical Pokémon.
