Godzilla: The Series S02E17 - Ring of Fire

A strange creature made of living flame attacks an oil platform in New Mexico. When H.E.A.T. and Godzilla arrive to stop it, Randy and Craven sense a chance to make a lot of money if they can exploit the monster's ability to regenerate energy. Once H.E.A.T has taken the creature out, Randy and Mendel sneak it back to headquarters for study, but things go badly wrong when the Fire Monster regains consciousness and starts burning down everything in its path.
