Welcome to Tromaville, New Jersey – a small American town, terrorized by criminals. The town’s corrupt mayor sits idly by, while muggers, robbers and teenage punks victimize helpless citizens. Among the residents of Tromaville is Melvin, a nerdy emaciated janitor at the local health club. That is, until he becomes The Toxic Avenger! A gang of thugs devise a cruel hoax that goes horribly wrong as Melvin is cast through a third story window into a vat of hazardous toxic waste. However, an unexpected metamorphosis takes place. As the chemicals take hold of his body, Melvin turns into the Toxic Avenger, doer of good, and brutal mauler of evil! The rest, as they say, is history! The excitement is non-stop as the hero sets out to single handedly wipe out the forces of evil that torment the people of Tromaville. The Toxic Avenger is non-stop entertainment that will leave the viewers glowing from the fun.What is UMDTM?UMD, Universal Media Disc, is a brand-new and groundbreaking optical storage medium, designed for the high speed and efficient delivery of digital entertainment content that can store up to 1.8 GB of digital data on a 60mm disc — or an entire feature film on a single UMD video.
