April Eagle is the daughter of Commander Eagle, and the engineer who designed and was in charge of Project Ramrod. She was trained at Cavalry Command under General Whitehawk. Before joining the Star Sheriffs she was a professional tennis player. In early episodes of the series, April had an unrequited crush on Saber Rider, which may explain why in the WEP produced episodes, April has a robotic horse named Nova with the abilities of Saber's Steed.
