Spider Bytez is the name commonly assigned to a minor monster appearing in the Back to the Sewer episode The Engagement Ring. Though unnamed in the episode, Spider Bytez was the name given to the unreleased action figure that the character's design is based on. In Back to the Sewer, April, under the influence of demonic powers, created two Spider Bytez creatures, albeit with slight redesigns and different colours. They attacked Casey and Raphael, but they were able to defeat them.
