Eclipse Cannon (Sonic X)

Eclipse Cannon is a major object that appeared in the anime series, ''Sonic X. ''It is a weapon of mass of destruction able to draw into the power of the seven Chaos Emeralds to destroy planets.

Background
Fifty years ago prior to the events of the anime, the Eclipse Cannon was built inside the Space Colony ARK alongside variety of objects and projects lead by the world's known scientist, Gerald Robotnik by a request from the government to protect humanity and for research. But the fear from the projects especially the "Project Shadow", caused the government sent the Guardian Units of the Nations to shut the colony and lay off all the scientists aboard, thus killing Maria, Gerald's granddaughter and closing the Eclipse Cannon. When Gerald saw Maria's name among people who had been killed in the colony, he gone insane and instead of helping humanity he wanted to take revenge on them. Based on his original project he reprogrammed Shadow as a doll to complete his plan. But Shadow was taken at the same time by the guardians and put in stasis, ending the plot temporarily.

Shadow Saga
Many years later, Doctor Eggman awakened Shadow and the black hedgehog lured on the doctor to gather the seven Chaos Emeralds and activate the Eclipse Cannon so he can use it to destroy the world. Working with the duo of both Eggman and Rouge the Bat (who was spying on them) to gather the Chaos Emeralds to the cannon, they collected five of them. Later, Eggman turned on the Eclipse Cannon with just the five emeralds and to send fear among residents of the planet and the President, the doctor blew out half of the moon. Subsequently, Sonic and his friends arrived to ARK to stop Eggman from launching the cannon the Earth, by putting a fake Chaos Emerald into the cannon's core to break the cannon. But unfortunately, their efforts were futile, as Eggman interrupted the plan, however, Sonic would later trick Shadow to attack him all the way to the Eclipse Cannon, harming much of the cannon. After the events of the Shadow Saga, the Eclipse Cannon was presumably left damaged and abandoned.

Features and abilities
The Eclipse Cannon is described as the ultimate weapon that is capable of destroying entire planets with the power of the seven Chaos Emeralds. Even when in the possession of five of the emeralds, the Eclipse Cannon's laser beam was able to shatter half of the moon. However, the cannon is not indestructible, as it can be damaged heavily by strong attacks like the Chaos Spears.
