How to Evolve Hattrem

Hattrem evolves into Hatterene by reaching level 42. No special items, evolution stones, or specific times of day are required. You can trigger this evolution through standard battles, using Rare Candies, or feeding it Exp. Candies. Ensure Hattrem is not holding an Everstone, as this blocks the evolution.

Evolving Hattrem is a straightforward process that relies entirely on gaining experience. Unlike many Psychic-type or Fairy-type Pokémon that require specific stones or friendship mechanics, this evolution is purely level-based.

• Target Evolution: Hatterene
• Required Level: Level 42
• Required Item: None
• Time of Day: Any

While the method is simple, the execution varies wildly depending on which game you are playing. Modern Pokémon titles offer distinct shortcuts to bypass the traditional grind and reach the level 42 threshold in minutes.

In Pokémon Legends: Z-A, navigating the urban environment of Lumiose City changes how you accumulate experience. Traditional tall grass grinding is replaced by completing specific Pokédex research tasks and engaging in urban trainer battles.

1. Focus on catching multiple Pokémon in succession without leaving the immediate district.
2. Complete Pokédex research tasks to earn passive team-wide experience points.
3. Defeat powerful Alpha-equivalent Pokémon roaming the city plazas to secure Exp. Candies M and Exp. Candies L.
4. Feed these candies directly to Hattrem from your satchel to instantly reach level 42.

Since the Legends format often removes held items during the main adventure, you do not need to worry about accidentally equipping an Everstone. The evolution prompt will appear on the left side of your screen once the level requirement is met, allowing you to trigger it manually from the menu.

In the Paldea region, reaching level 42 is best achieved through targeted farming rather than passive progression. The fastest method involves hunting Chansey in North Province (Area Three) near the Fairy-type Team Star base.

1. Open your picnic and create a Ham Sandwich using Ham, Pickles, Mayonnaise, and Mustard to activate Encounter Power: Normal Lv. 1.
2. Walk around the dirt paths to spawn massive groups of Chansey.
3. Engage them in manual battles using a physical attacker, as Chansey has incredibly low physical defense.
4. Keep Hattrem in your party to soak up the shared experience points via the passive Exp. Share.

Alternatively, farming 4-star and 5-star Tera Raid Battles provides a massive stockpile of Exp. Candy L and Exp. Candy XL. Feeding just a few of these to a freshly caught Hattrem will push it past level 42 instantly. Always ensure you are feeding candies from the bag rather than relying on auto-battles.

Players frequently encounter roadblocks when trying to evolve Hattrem, especially in Generation 9. The most common culprit is the Let's Go auto-battle feature. If Hattrem hits level 42 while defeating wild Pokémon using the R-button auto-battle command, the evolution sequence is deliberately bypassed by the game engine. To fix this, simply level Hattrem up to 43 using a manual battle or a Rare Candy.

Another frequent issue is the accidental equipping of an Everstone. If you received Hattrem via a Surprise Trade, the previous owner might have attached this item. Check Hattrem's summary screen and remove the Everstone if present. Finally, pressing the B button during the evolution animation will cancel the process entirely. If you do this by mistake, you must level Hattrem up again to trigger the screen.

While Hatterene boasts massive Special Attack, keeping Hattrem unevolved is a highly strategic choice in the Smogon PU tier (where it currently sees 1.9% usage). By equipping an Eviolite, Hattrem gains exceptional bulk, allowing it to function as a premier defensive pivot and hazard controller.

Hattrem's primary value comes from the magicbounce ability, which reflects entry hazards like Stealth Rock and Spikes back at the opponent. This makes it a phenomenal partner for Pokémon weak to hazards, such as Typhlosion-Hisui, Shiftry, and Volbeat. In this tier, Hattrem utilizes nuzzle for guaranteed speed control and mysticalfire to cripple opposing special attackers.

Instead of acting as a pure wall, Hattrem excels as a dedicated support unit. It frequently runs healingwish to fully restore a weakened sweeper like Venusaur late in the game. Alternatively, players can run an ejectbutton to set up trickroom and immediately pivot out to a slow, hard-hitting teammate. Evolving into Hatterene forces you into higher competitive tiers, so carefully consider your team composition before letting Hattrem reach its final stage.
