Special evolution methods in Pokémon GO
Most Pokémon evolve with just candy. The interesting ones don't — they need an evolution stone, a specific lure, a particular gender, the right time of day, or a buddy walk. This guide covers every special evolution method with examples.
Sinnoh Stones are required to evolve certain Gen 1-3 Pokémon into their Gen 4 evolutions. Each evolution also requires 100 Candy. Sinnoh Stones come from PvP rewards, Research Breakthroughs, and weekly milestones.
Lickitung must know Body Slam (Community Day exclusive move).
Strong Electric attacker.
PvP Ghost pick.
Unova Stones evolve specific Gen 4-5 species. Same source as Sinnoh Stones: PvP rewards, Research Breakthroughs, weekly milestones. Each evolution requires 100 Candy.
Top Fire/Ghost attacker. Lampent itself evolves from Litwick with 50 Candy first.
Electric/Ground PvP pick.
Niche Bug/Steel attacker.
Some species evolve based on buddy friendship — either earning hearts as your active buddy or evolving at specific times of day. Time-of-day matters for the dawn/dusk pairs.
Some Pokémon evolve only through trading (or, in PoGO, after a trade has been completed with that species). The trade triggers free evolution — no candy required.
Specialty Lures unlock specific evolutions when used at a PokéStop within range of the evolving Pokémon. Lures last 30 minutes — multiple evolutions are possible per Lure.
Specific evolution items are required for certain species. Items come from research, gym rewards, or rare PokéStop drops.
Some species evolve based on whether the in-game clock is day or night. In-game time follows your device clock (or weather data when available).
Evolve during DAY.
Evolve during NIGHT.
Evolve during DUSK (very narrow time window).
A handful of species have gender-locked evolutions. The gender is fixed at catch time, so you may need to catch multiple to find a male/female of a specific species.
Female only + Sinnoh Stone + 100 Candy.
Either gender → 100 Candy → Gardevoir.
Male only + Sinnoh Stone + 100 Candy.
Male Burmy → 50 Candy → Mothim.
Female Burmy → 50 Candy → Wormadam (form matches the cloak Burmy was caught with).
Edge cases that don't fit other categories — special-research-required, Mega-only, etc.
Originally Halloween 2018 Special Research. Now spawns in events. No evolution.
400 Meltan Candy. Meltan spawns only from Mystery Boxes (opened with Pokémon HOME transfer).
Buddy walk: 1 candy.
How do I get a Sinnoh Stone?
Sinnoh Stones come from: weekly Research Breakthrough rewards (~1 in 8 weeks), PvP rank rewards (every 5 ranks gives a chance), Trainer Battles vs Team GO Rocket leaders, and special event tasks. They are NOT obtainable from regular PokéStop spins.
How do I get a Unova Stone?
Same sources as Sinnoh Stones: Research Breakthroughs, PvP rewards, and special event tasks. They are scarcer than Sinnoh Stones — events tied to Gen 5 releases are the most reliable source.
Do I need the original Eevee for each evolution trick?
For the name trick — yes, the Eevee must be renamed (e.g. "Rainer" for Vaporeon) BEFORE you evolve. The name resets after evolution, so it's a one-time-use per evolution per account.
What is King's Rock used for?
King's Rock evolves Slowpoke → Slowking (alternative to Slowbro) and Poliwhirl → Politoed (alternative to Poliwrath). Each evolution also requires 100 Candy. Items come from Field Research breakthroughs + 7-day stop-spin streaks.
Can I evolve a Pokémon without the special requirement?
Sometimes, yes. Eevee evolutions have alternate paths — name tricks bypass the buddy-walk or lure requirements for one-time use. But for stone-required evolutions (Sinnoh / Unova / King's Rock / etc.), there's no shortcut — you need the item.
