Sonic Power Cannon

The Sonic Power Cannon (ソニックドライバー) is an object that appears in the Sonic X anime series. It is the most powerful weapon on the Blue Typhoon and was designed by Tails.

Description
The Sonic Power Cannon takes advantage of chaos energy and Sonic's spinning ability by using Sonic himself as its ammunition, although it can be used with anyone who has the same ability. When engaged, the Sonic Power Cannon draws chaos energy from the Master Emerald while Sonic spins on a platform in the barrel to charge up power. As an alternative power source, it can use Rings instead. Once charged, Tails fires Sonic as a highly powerful projectile. If too much power is built up however, the Sonic Power Cannon will be destroyed.

If Sonic is not present, the Sonic Power Cannon can still fire a powerful energy blast.

Metarex Saga
The Sonic Power Cannon was designed by Tails and used the Master Emerald as its power source. When Sonic and his friends went into space to stop the Metarex, the Sonic Power Cannon was primarily used against this alien scourge.

In "The Cosmo Conspiracy" Tails uses the Sonic Power Cannon to launch Shadow in attempt to stop him from killing Cosmo.

In "A Fearless Friend", Tails was forced to use the Sonic Power Cannon to destroy Final Mova and Cosmo herself. For this task, Super Sonic and Super Shadow were both used for its ammunition at the same time. Once Super Sonic and Super Shadow were fired, the force had so much impact that the Sonic Power Cannon was destroyed.

Archie Comics
The Sonic Power Cannon makes an appearance in the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics. In this media, it is one of the weapons for the Freedom Fighters' Sky Patrol, though it does not use Sonic as a projectile. It was first deployed to destroy the War Walrus when it was send to destroy the Sky Patrol.

Trivia

 * The Sonic Power Cannon's Japanese name is almost the same as the name for the Sonic X anime series' Japanese theme song.
 * Due to Tails' idea to power the Blue Typhoon with the Chaos Emeralds, it is possible that the Sonic Power Cannon was planned to use the chaos energy from the Chaos Emeralds to power it, but was adjusted to use the Master Emerald's energy.
