I would admit it. When I was young, I had a crush on the Zandra, who was the personal aide of Prince Zardoz, commander-in-chief of the Boazanian Invasion Forces, and robotics adviser of the beast fighters sent to Earth to destroy Voltes V.
In the Japanese anime saga (SPOILER ALERT), she is in love with the Boazanian prince although it was unrequited. Until she sacrificed her life for the one she loved, and it was only then that Zardoz realized that he also cared for her. Such Shakespearean or Greek tragedy for a young mind! Not to mention the tragedy for the Armstrongs (but that is another story!).
Anyway, in the adaptation by GMA-7 dubbed Voltes V Legacy, the young actress who would play Zandra would be Leizel Lopez. Here is her photo from Instagram (credit: GMA-7 digital). Try to compare her with the graphic from Toei Art (she looks the part, right?).
