Developer Niantic has recently updated their Raid Bosses for the current season, and legendary Pokemon Ho-Oh is no longer available in Pokemon Go as a result.

The company seems to be favoring the first and third generations of Pokemon, as both Ho-Oh and Lugia have been removed, while Kyogre and Mewtwo remain in place. It wouldn’t be too surprising for Rayquaza to make a come back here soon.

With this change, as well as others, the full roster of Raid battle bosses is as follows.

Five Star Bosses

• Mewtwo
• Kyogre

Four Star Bosses

• Tyranitar
• Aggron
• Absol
• Walrein
• Machamp

Three Star Bosses

• Starmie
• Sharpedo

Two Star Bosses

• Tentacruel
• Croconaw
• Marshtomp
• Mawile

One Star Bosses

• Shellder
• Omanyte
• Kabuto
• Wailmer

You may want to strive for Mewtwo while you still can. There is no certainty as to how much longer they’ll be available.
