Mercenary scientist Professor Gordon develops an indestructible material called Neophryte and decides to sell it to the highest bidder. So he summons agents from both Gallactor (Egobossler's first officer, Kempler) and the ISO (the Gatchaman, naturally) to meet alone on a spot he specifies. Of course Kempler doesn't come alone, but much to both his and Ken's surprise, neither does Ken. While the Gallactors and the rest of the Kagaku Ninjatai take part in a snarling standoff outside, Gordon, Kempler and Ken negotiate. Kempler offers money, while Ken refuses to haggle, stating honor and decency as his reasons (and knowing as Gordon does that once he withdraws his protection, Gallactor will simply take what they want by force). Worried about his father, Gordon's son finally ends the standoff and uncovers the compound for both sides to fight over. Joe uses a bazooka loaded with Neophryte to blow a hole in the monstermech that appears at the end.
