Shadow Pokémon hit harder than their normal counterparts but come with real tradeoffs — and deciding whether to purify one is one of the more permanent choices in the game. Here’s how the Shadow system actually works.
How to Get a Shadow Pokémon
Shadow Pokémon come exclusively from Team GO Rocket — defeating a Grunt, a Team GO Rocket Leader (Cliff, Arlo, or Sierra), or Giovanni gives you a chance to catch the Shadow Pokémon they used in battle. They’re instantly recognizable by the purple-red aura and glowing eyes in their sprite.
What Makes a Shadow Pokémon Different
Shadow Pokémon get roughly a 20% boost to Attack, at the cost of about 17% less Defense — a genuine glass-cannon tradeoff that makes them hit harder but faint faster. They also start with Frustration locked in as a Charged Move, a weak attack that only becomes usable once you either purify the Pokémon or teach it a different Charged Move with Stardust and Candy.
One important restriction: Shadow Pokémon can’t be placed in Gyms to defend. They’re built for offense — raids, PvP, and Trainer Battles — not defense.
Should You Purify It?
Purifying a Shadow Pokémon costs Stardust and Candy, and in exchange it: removes the purple aura and Frustration, sets a guaranteed IV floor (each of Attack, Defense, and HP will be at least a set minimum after purification, often improving a mediocre roll), and gives it access to any Charged Move it could normally learn. The tradeoff is that it also loses the Shadow Attack boost, dropping back to normal stats.
For raid attacking, keeping a Pokémon Shadow is almost always better — you want the highest DPS possible, and a slightly lower Defense rarely matters when a raid boss is the one taking the damage. For a PvP pick or something you plan to keep long-term without needing maximum aggression, purifying can be worth it for the guaranteed IV floor and access to Frustration-free battling from the start.
Building a Shadow Roster
Since Shadow Pokémon are some of the best raw DPS options in the game, several of the top picks in our Best Attackers by Type guide are specifically Shadow forms. If you’re regularly battling Team GO Rocket for Shadow Pokémon, our Team GO Rocket Leaders and Giovanni guide covers current lineups and counters.
Purification Costs by Pokémon Type
Purifying is not free. The Stardust and Candy cost scales with how “rare” the base Pokémon is to farm Candy for, not with its CP. Here is the breakdown that applies across the game:
| Candy Family Type | Example Pokémon | Stardust Cost | Candy Cost |
|---|---|---|---|
| Common (1 Candy per catch) | Rattata, Zubat, Weedle | 1,000 | 1 |
| Starter-tier (3-5 KM Candy) | Charmander, Bulbasaur, Machop | 3,000 | 3 |
| 10 KM Candy families | Larvitar, Beldum, Dratini | 5,000 | 5 |
| Legendary | Suicune, Latios, Regirock | 20,000 | 20 |
Purifying also instantly raises every IV stat by 2 (capping at 15), sets the Pokémon’s mood to Best Buddy-eligible faster, and removes Frustration entirely. In exchange, you lose the permanent Attack boost and the Shadow aura.
How the Shadow Bonus Actually Works in Battle
Shadow status changes two multipliers that apply in every format, including Gyms, Raids, Trainer Battles, and PvP: Attack is multiplied by 1.2 (a 20% increase), and Defense is multiplied by 0.833 (roughly a 17% decrease). Both apply automatically and stack with weather boost, so a Shadow Pokémon in its boosted weather can hit noticeably harder than a Purified or Normal one.
In PvP leagues, that Attack boost can push a Fast Move past a damage breakpoint that the non-Shadow version can’t reach, meaning more damage per turn without spending extra Energy. The tradeoff is the lower Defense, which means Shadow Pokémon fall faster to incoming Charged Moves, so shielding decisions become tighter. This is why Shadow Pokémon are generally stronger picks for aggressive, fast-paced attackers and riskier picks for Pokémon meant to stall or tank hits.
Best Uses for Shadow Pokémon
Because of the Attack multiplier, Shadow Pokémon are almost always the better choice for raid attacking and Team GO Rocket battles, where you control the matchup and want maximum damage output before you faint. Check our Best Attackers by Type guide for which Shadow forms currently top each type’s DPS rankings.
For Gym defending, the lower Defense makes Shadow Pokémon a weaker pick than their Purified or Normal counterparts, since defenders benefit more from bulk than from Attack. If you’re stocking a defensive roster, purify those Pokémon first.
