The Eclipse Cannon is a weapon of mass destruction installed on the Space Colony ARK.


Under Eggman's Control

At some point in the past, Dr. Eggman used the Space Colony ARK to blow up half of the moon by firing its Eclipse Cannon in order to show his power. (StH: #5)


The Eclipse Cannon was not shown in much detail, as it was only ever shown in a flashback where it was in the distance and firing a blast. What can be seen is that it has four pieces surrounding the circular part where it fires its blast.


The Eclipse Cannon is a weapon powerful enough to reduce half of the moon's surface to rubble in a single shot.

Background Information

  • The Eclipse Cannon was based on the weapon of the same name in the Sonic the Hedgehog video game series, where it first appeared in Sonic Adventure 2 and later Shadow the Hedgehog. It was unnamed in the comic, but is considered tier 2 canon by this site's canon policy, as it does not contradict already established canon from tier 1. In the game, its fire power is high enough to pierce the stars.
