Metagas

Metagas appeared in 1986 TV series called Choushinsei Flashman. Metagas is a Beast Warrior utilized by Sir Cowler with assistance of the other Mess forces, going behind the back of Lee Keflen in the process. The Beast Warrior's body is comprised of many smaller slugs, which were separated off and used in a scheme to make children buy them making them believe that the slugs can create gold by eating various metals. However, the slugs actually created from the metal not gold but a gas that had various properties, including being combustible and the ability to melt other metals. Jin discovers this as he tries to help a boy hoping to use the special slug to buy a violin for a girl he liked, yet the boy nearly gets killed when it melts a pole he was standing under. The Beast Warrior becomes stunned by the Super Spear before being destroyed by the Rolling Vulcan; after Kuragen rebuilds and grows it, it is ultimately destroyed by Great Titan.
