- For a list of Ray Series robos, see here.
The Ray Series is the most well-known and popular robo series. Each Custom Robo installment features this common series, and a robo from the Ray series is always the first robo given to the player. These robos are famous for generally having good leg balance and weight distribution. All members of the Ray series have the word "Ray" in their names. The Ray series is not technically a model type, so a majority of the Ray series are Shining Fighters, except for some like Ray Sky, which is a Lightning Sky Model.
