Gamma Robo
Beta Robo is one of three robots that combine to become Albegas, from the anime series Lightning Wind God Albegas (Kousoku Denshin Albegas 光速電神アルベガス).
This is the second piece I aquired in the Gyro Mecha line. I got the first one way back in 2007, the Blue one (Beta Robo). He was the easiest to find. A few years later, I found this one (Gamma), and then finally the super-elusive Black one (Alpha). These are exceptionally hard to track down, with the black one being the rarest.
This toy is relatively unknown amongst collectors. It is one of three small cheap Albegas robots that can combine to form the giant Albegas robot. Even though it is cheap and hollow, the toy fully combines.
In addition to the combining features, Gamma Robo comes with a metal gyro and a ripcord. This is known as the Gyro Mecha. All three toys in this line are labeled this way. You can take the individual robots apart and insert the gyro mechanism into them, pull the ripcord and watch the toy zoom off across the room. The package shows the combinations, and they make little sense.
The toys come packed in a Styrofoam tray inside a window box. The packaging is nice, and the toy comes with a small instruction sheet that shows how to assemble the robot.
