Three exciting, self-contained stories that further explore these classic heroes and expand upon the continuity of Mad Cave's ongoing Gatchaman series!
Ken goes undercover to infiltrate an underground gambling ring where martial artists from around the globe fight to the death. There, the winners are captured and brought to a secret Galactor recruiting base. If they refuse to join, the captives are dropped in the jungle and hunted as prey for Galactor's training program. Can anyone make it out alive?

Meanwhile, an elite squad of motorcycle-riding death bikers have successfully hijacked an armored train transporting experimental International Science Organization tech. These thieves are fast and ruthless—they carry out their orders with razor-sharp efficiency. The only thing in their way is Jun the Swan and her G-3 Sonic Car mecha.

Lastly, Ryu finds himself on a high-seas oceanic adventure to defend his harbor and its citizens from an attacking group of scavenging pirates!
