Walt is a heroic figure within the LED Powers series, specifically part of the Laser Microman subgroup. He stands approximately 8 centimeters (3.25 inches) tall, featuring a translucent blue plastic body construction and the distinctive chromed head signature to Microman figures. His articulation enables dynamic action poses, consistent with the line's engineering standards.

A backpack unit powers a red LED light in Walt's chest, a technological innovation for the series. Multiple 3-millimeter ports on his body and backpack allow attachment of weapons and accessories. His modular equipment includes armaments configurable for hand-to-hand combat or projectile firing, plus a shield component that integrates into a larger "Magneshield" defensive system.

Walt operates as part of a team with other Laser Microman characters like Odin, Arthur, Izam, and Edison. Their core conflict pits them against the biomechanical Laser Acroyears – the duo Acro-Jekyll (blue) and Acro-Hyde (red). These adversaries blend organic dragon-like elements with mechanical components featuring rocket launchers and flip-out sabers.

He shares design and engineering principles with later additions like Laser Master Zett, including the chromed appearance and weaponry systems. Zett, however, features gold chrome and a unique dragon-helmet sculpt. Broader Microman lore establishes Walt as one of the cybernetic "Micros" from the planet Micro Earth, who adopt the guise of action figures while on Earth. Figures within this universe typically incorporate standardized 5-millimeter interchangeable connectors and ports, though Walt's specific compatibility remains undetailed.
