Volt Frigate

Here's Little John's Frigate!

It would've been uber-cool if they added an Octo-One figure in GX-31V! ^_^

Little John and Octo-One

From Wiki --

"Little" John Armstrong (Hiyoshi Gō) is a genius in inventing automatons. He has been interested in learning mechanics, robotics, and electromagnetism since a very young age. He was considered a genius by many university professors. He even created a funny little octopus-robot called Tako-chan ("Octo-One" in the dubbed version). But to his big brothers, Ken'ichi and Daijirō, Hiyoshi will always be a little brother, a child who never felt the warmth and love of a real father. He also excels in swimming and diving. Because of his exceptional talents, Hiyoshi was asked to join the Voltes V Team as a technical handyman, specifically for repairs during field operations. His uniform was light green. Voiced by Noriko Ohara in the original Voltes V series. Volt Frigate (Legs) is Hiyoshi's vehicle.
