What's your favorite Voltes-V episode?

Voltes-V is a Japanese anime cartoon series that ran during the 1970's. The earth is invaded by alien forces called the Bozanian and it's up to the Voltes team to stop them. The team consists of Steve, Mark, Big Bert, Little John, and Jaymee. Each of them pilots a spaceship that combined together will form the formidable ultraelectromagnetic giant robot Voltes-V. This anime is so cool because in my opinion it was way ahead of it's time. Anyway, back to my main topic, my most favorite
episode has to be the when Dr. Smith has to sacrifice himself to save the Voltes team, it's probably the most emonitional episode of the series. Let's Volt In!!!
