A Raid Boss or Boss Pokémon is an extremely powerful Pokémon that has very high CP. It hatches from a egg which appears atop a Gym upon the beginning of the Raid Battle. A countdown will display the time until the egg hatches and the battle begins.


Upon using a Raid Pass to join the battle, the Trainer and up to 19 other Trainers work together to defeat the Raid Boss. If a Raid Boss is successfully defeated within the three-minute time limit, those Trainers have the chance to catch a decently powerful Pokémon of their own.[1][2]

A Raid Boss can battled as many times before it is either defeated or the one-hour time limit expires.

List of Raid BossesEdit

Main article: List of Raid Bosses

There are a limited number of Pokémon that can be possible Raid Bosses. The availability of these Raid Bosses have been altered once; excluding the Legendary Pokémon.

In past events (regional ones specifically), there have been exclusive Raid Bosses that cannot normally be encountered at Gyms.

Raid Boss CP formulaEdit

The formula is identical to the traditional CP Formula; except the stamina and CP scalar portion in the divisor are replaced with a tier scalar which represents the Raid Boss's HP and the IVs for attack and defense are fixed to 15 (maximum IV value).

$ {BCP = \frac{(Base Atk + 15) ~ \times ~ \sqrt{Base Def + 15} ~ \times ~ \sqrt{TierScalar}}{10}} $

Where TierScalar is:

  • Tier 1: 600
  • Tier 2: 1,800
  • Tier 3: 3,000
  • Tier 4: 7,500
  • Tier 5: 12,500


  • The Raid Boss icon is based off of Rhydon's face — who was the first Pokémon designed and programmed into the original game.[3] There are also various Rhydon statutes that can be found throughout the game as well.
  • On November 4, 2017, the raid bosses were rotated for the first time.[4]
