Alpha 5

In the early days of the series he often acted like a younger brother to the Power Rangers, always wanting spend time with them and learn things (such as learning "hip-hop-kido" from Zack). He matured slightly as the series progressed, but always remained a naive, child-like assistant. Residing in the Command Center with Zordon, he served as the Rangers' technician, constructing weapons for them to use against the forces of Lord Zedd and Rita Repulsa.

It has been revealed that Alpha was constructed on the planet Edenoi by Kin Lexian, the grandfather of the Masked Rider.
