Metal Skin Panic MADOX-01 (メタルスキンパニック MADOX-01, Metaru Sukin Panikku Madokkusu Zero Wan) is a 1987 original video animation produced by AIC, Soeishinsha and Pony Canyon and directed and conceptualized by Shinji Aramaki. It has been licensed in the United States by AnimEigo. The plot centers on a mechanic who comes across the MADOX-01, a heavy powered armor suit designed to fight enemy tanks. After getting trapped in the suit before reading the user's manual, the military attempts to reclaim it, leaving him with no choice but to defend himself.

Aramaki, who was in charge of the original idea, directing, and mechanical design, later recalled that he was still in his 20s and didn't know what to be afraid of when he made the OVA, which was also his directorial debut.
