Kagaku Ninja Tai Gatchaman ("Science Ninja Team Gatchaman") has been brought over to the United States in two separate versions (not counting the 94 OAVs, which were all-original animation, or Eagle Riders, which was derived from the sequel series). There were a total of 105 Gatchaman episodes, and not all of them were translated in either Sandy Frank's Battle of the Planets (1978) or in Ted Turner's G-Force: Guardians of Space (1986). To make the issue even more confusing, some episodes were translated in BotP that never appeared in G-Force, and vice versa. And let's not even get started on the issue of the plot manglings that went on...

Below is a list of all 105 original Gatchaman episode names (translated from the Japanese by Alara Rogers & Co.) with the corresponding episode titles for both American translations. Bear in mind that BotP and G-Force did not show the episodes in the same order that they aired in the original Gatchaman. In fact, especially in the latter half of the series, continuity is shot all to hell and gone. Still, this list should prove helpful if you want to know which episode in BotP and/or G-Force was translated from which episode in the original.

You will find synopses and scripts for many of the original Gatchaman episodes at Alara Rogers' website. For storylines and commentary from all three versions of the series, visit Carolyn Kaufman's website. Much thanks to both of these ladies for their assistance in compiling this list.

Much credit is due to Alara Rogers for the titles of the original Gatchaman episodes and for the table layout, and also to Carolyn Kaufman for the titles of the Battle of the Planets and G-Force episodes. I couldn't have done it without you, ladies. ^.^,v..
