During Goku younger days, Goku faced a evil secret organization that was after the Dragonball. That secret organization was The Red Ribbon, the most fear of society of organized militant. Goku faces them head on and overcome them. In later part of the story, Red Ribbon was also involved with the creating of Cell.
Beside Capsule Corp, Red Ribbon also have many forms of vehicles and one of them is the Sky bike. Although Goku never really ride one of these in the comic but on the poster. Some of you may find this familiar.
This vehicle is very much in military class. Painted with Flat green.
I really like the Goku looks especially with his goggles on his head.
See the details of the AK-47 look alike guns?
See the Nyoibo on Goku?
Finally it is free to fly.
Fly up in the sky. :)
