King Plane (キングプレーン Kingu Purēn) is the second boss from the second King Castle stage in Mega Man & Bass. It is a giant plane that is fought over a bottomless pit on a series of small, floating platforms that move out of the screen, forcing the player to move from one to another. It reappears later in the third section of King Castle, fusing with King and the King Tank into Jet King Robo after King is brainwashed by Dr. Wily, in a final effort to defeat Mega Man and Bass.


  • It shoots bubbles at the player. However, the bubbles are not harmful but have either a health item, a weapon capsule, or a flash bang in it. If the player touches or shoots on the former two items, the player will be able to use them. If the player touches or shoots the flash bang, however, the whole screen will flash white, leaving the player temporarily blinded.
  • It shoots out a fist that destroys the platforms that are in its path. It takes quick movement to dodge or use the Lightning Bolt to hang in the air temporarily for timing the platform that the fist didn't destroy. The fist can be destroyed.
  • It shoots an undodgeable ray of light. The player has to damage its core to stop it from using the attack, which can be easily done with the Remote Mine or Lightning Bolt.
