Voltron is, perhaps, one of the fondest remembered television shows of the 80's. Five brave explorers (shortly thereafter four and a princess) set out to find the one thing in the universe capible of standing up to King Zarkon... Voltron, a powerful robot made of five robot lions, and powered by purity of heart and soul.
Of course, the formation sequence was the part of nearly every episode most people looked forward to. The classic sequence, beginning with "Activate Interlocks", marked what everyone always knew to be the beginning of the end for the Robeast menace of the day.
Paving the way for Power Rangers, Voltron remains popular to this day.
GO, VOLTRON FORCE!
