The Slayer Canon is a weapon on board the Wigwam, built by Xeno and Cicero, for the first time since Xeno doomed his planet, It works through Fusion of Adamantium particles, provided by Ynot, and the only fuel source powerful enough to fuel this was Sasukens lightning blasts.When fired, it has the ability to create massive holes in a planets crust, but apparently can't harm a single Caged Lion. It was named because it's so strong it can injure even True Dragons like a Dragon Slayer. It shreds Dragon scales -- It shatters Dragon bones -- It crushes Dragon entrails. Just like the Dragon Slayers it's named after.
