King Galaspark

King Galaspark is the main antagonist of the Galaga series and the leader of the Space Bugs but doesn't make an appearance until at the last level of Galaga Arrangement. He is battled in the Enemy-Comb Zone and is a huge red fly with purple wings, but his body gets redder as the player progresses through the three phases of the boss battle. After you deal enough damage to him he explodes.

1st Phase
After the rocket ship encounters King Galaspark in the Enemy-Comb Zone and begins to fight him, Galaspark simply moves back and forth from each side of the screen and summons giant Yellow Minion Bugs as well as shooting bullets himself.

2nd Phase
When the rocket ship start to deal more damage onto Galaspark, he becomes aggravated and will drift back and forth vertically as well as side to side. He also starts summoning large groups of various Space Bugs which become extremely difficult to avoid Galaspark's attacks as well as trying to keep damaging him.

3rd Phase
By the time the rocket ship deals enough damage to Galaspark, he stops summoning Space Bugs but becomes even more enraged. During in between patrols from the sides of the screen, Galaspark shoots bigger bullets all over the screen and will then dive towards the ship in an attempt to destroy it in one attack.

4th Phase
Once the rocket ships has put a significant amount of damage on Galaspark, he becomes paralyzed and eventually explodes after he is defeated by the rocket ship. The rocket ship then takes off and the end credits appear.
