Iron King

Having constructed a new base within a condo in Tokyo, the Titanian invaders finally had set their sights on the largest city in Japan. Attracting a lot of attention for the condo they paid millions for, including both Goro and Gentaro, Titanian Operative #6 transformed in order to lure them away. As it began to suck everything up with its vacuum-like belly, Goro transformed into Iron King! The red hero challenged the evil space bug and beat it down, eventually causing it to revert back to its human-sized form and retreat after suffering two explosive flashes in a row.

Gentaro and Goro were in hot purist and ran back to the nefarious condo in order to rescue a group of children whom had been put under Titanian control. With Goro transformed into the hero outside the condo, the invaders’ plans were foiled again. Operative #6 transformed into Gokibura again and battled the red hero in the streets! Smashing through buildings, the two warriors were locked in combat but it seemed as if the cockroach-like behemoth had gotten the upper hand. Using its vacuum to draw in Iron King, it began to pummel the superhero. When all seemed lost, Gentaro interfered. He threw a grenade into its vacuum, severely wounding the villainous monster. Falling back in agony, Gokibura was finished off within a huge explosion by twin bolts of energy from Iron King.
