The Queen and King are the twin bosses of the Galactic Jungle. As most of the buildings in the Galactic Jungle are based off of chess pieces, these bosses are based off of the King and the Queen in chess.
Battle
The Queen is battled first. The queen is a giant spaceship flying around the top of Treetop Turrets, the final level in Galactic Jungle). First it will send out some Baki ships that move similarly to the enemies in the arcade game Galaga. After the ships are defeated, it will start shooting fireballs. After dodging those for a while, the actual boss is fought. The first thing that is fought is a device that flies up and down, shooting fireballs at the Hero. The best strategy for this is to shoot it while staying in one place (preferably the top of the screen) then when it shoots a fireball at move out of the way and continue shooting. After that is defeated, the Hero moves through another section of the ship that fires a yellow laser, and onto the last part of the Queen. There are four other lasers that must be avoided while shooting at the engines. After the three engines are destroyed, the Queen is destroyed.
The King is fought next on the surface of a moon-like planet. Using regular shots from the spaceship takes a long time, so dropping lots of bombs on him while avoiding the missiles is the best strategy. NOTE: The laser that he shoots instantly kills the Hero if it touches him, but luckily, the laser gives plenty of time to move out of the way while it is charging.
Background
These machines are used mainly for the defense of the Council's true identity, Click. Apparently, they do not serve any other purpose.
