Sandworms are an animal in The Transformers:Infiltrators. They reside on AX-IV, and absorb weapons from their prey. They are silicon-based lifeforms, and are practically indestructible from the outside. They can let loose a devastating sonic blast and have teeth harder than diamonds, allowing them to kill Cybertronians with ease. They can also access any weapons they have absorbed. They can grow up to a mile in length, and are surprisingly stealthy.
