Jeffrey Kensaki (ジェフリィ・剣崎, Jefurii Kensaki) is Green Eagle (グリーンイーグル, Gurīn Īguru) of the Jetmen. A musician who takes over for Gai (Black Condor) in the somewhat non-canon (for the TV series) manga epilogue since it was never shown on TV. Since Ako (Blue Swallow) is then an idol singer, Jeff is an eager fan of her. He takes a major role in the final battle.
