Boss Pokémon (more commonly known as bosses) are rare types of Pokémon, usually tougher and larger than normal Pokémon. Their names come in four colors: green, blue, red, and yellow; in ascending order of difficulty. The rarer the boss, the more drops when defeated.
You will also be able to see the names above the heads of Boss Pokémon from further away than the names of regular Pokémon.
As of 2.2.1, Boss Pokémon no longer show their level outside of battle, and are at a significantly higher level than before. Bosses scale to 5/10/20 in combat above your highest level party Pokémon depending on colour. This resets each time the wild boss Pokémon is fought;
- A player who fights a wild blue boss with level 80 Pokémon will scale it to level 90.
- A player who fights the same boss with level 85 Pokémon will scale it to level 95.
- The maximum level a boss Pokémon will be is 140, which will occur if you have a level 100 Pokémon with you and it is a yellow boss.
The moveset of a wild boss Pokémon will also change with each battle, however growth, nature, and IVs will not. Bosses will be scaled according to the strongest pokemon in your party.
As of 2.3, Boss Pokémon can be spawned with /pokespawn <pokemon> boss<#>, e.g. /pokespawn lapras boss4 for a yellow boss Lapras. They are also tinted in the colour of their name. They can't be caught. The message if you throw a pokeball at it out of a battle will tell you that you can't catch a boss pokemon, and in battle it won't let you access your pokeballs.
- Poké Ball discs
- Poké Ball lids
- Poké balls (including Master Balls)
- Evolution Stones
- Held Items (Exp. shares, power bracers, everstones, etc.)
Note: The higher the difficulty of the boss, the more loot a player gains from boss Pokemon. For example, a blue boss may drop a Wooden Hammer, a Poke-ball, and a Burn Heal. A yellow boss may drop an Everstone, and Exp. Share, a Master ball, or other very good loot. Bosses are also the easiest way to get Master Balls in Pixelmon, the other possible way being Hidden Grottos. Before 3.0, Bosses were the only way to get a Master ball. They also come in pink and purple.
