Bio Robot Fighter X

Bio Robot Fighter X (ja. 有機機械戦士X, hepburn. Yúki Kikái Sénshi X, literally Organic Machinery Warrior X) is a prequel single-episode story to Chip-chan Kick audio novel. Probably it was also an idea for the most famous Hideo Kojima's Metal Gear series. 
==Plot==
The story is based on the former NORAD agent with the code name "Forest Warden" (ie. The Druid) worked at the Special Intelligence Division named WOLFHOUND (referenced to FOXHOUND) that was followed under the orders of Forest Serpent (referenced to Naked Snake). The mission was to engage the Soviet Union's nuclear diversion to USA and to prevent it to launch their secret weapon named "Garish Gear" Raptor (referenced to Metal Gear Rex). 
===Warden's mistake===
Nasumi (the real name of Forest Warden) had to save the Soviet scientist named Sylvester Raikov from the Belobyl (referenced to Chornobyl nuclear incident) because the last helped Richard Jones (the real name of Serpent) to find out the weak points of Gear Raptor. But Nasumi promised once to save Sylvester from his death... even if he will die. Nasumi didn't even know what is "save somebody from death even if somebody dies" before the "Chip-chan Kick" audio novel plot.
