Pokédex notes

Shadow Mewtwo is a Shadow Psychic Pokémon in GO. Shadow variants deal extra damage in raids and PvP but take more hits — compare purified vs Shadow before investing.

Where in GO: Team GO Rocket Grunts, Leaders, and Giovanni

Invest tip: Power up high-Attack Shadows after Frustration removal. Prefer Psycho Cut + Psystrike. Purify only if you want Mega Mewtwo.

Team GO Rocket

Shadow versions hit ~20% harder and take ~20% more damage. Use Psychic typing weaknesses quickly — they punch above their weight but faint faster than normal.

Defeat the Shadow in battle, then use a Rescue Rocket Radar or standard Rocket battle rewards to catch it. Purify or keep Shadow based on whether you want bulk (purified/normal) or raid DPS (Shadow).
