The two sequel series, Gatchaman II and Gatchaman F were combined into one and translated as Eagle Riders in 1996, with yet more changes to audio and character names.
It is agreed among both anime and tokusatsu fandoms that Gatchaman was the originator of the Sentai concept and set the bar for all transforming hero teams; from Super Sentai to Magic Girls and beyond.
Gatchaman is one of many anime series in in which its five main heroes have different features wherein two of its members, one of them the leader are both thin and of the same height, another one being the most overweight, one being the shortest and youngest and another one being the only female member.
Gatchaman, originally released in the early 1970s, was transformed into the English-language series Battle of the Planets, G-Force, and Eagle Riders.
Each member of the Gatchaman crew has his or her own preferred form of transportation, which has the ability to transform into a combat vehicle worthy of standing against the forces of Galactor.
Ryu is the only member of Gatchaman with a family, and in a way, this sets him apart from the rest of the team at times.
