Getter Robo G (ゲッターロボG, Gettā Robo Jī), known as Starvengers in the United States, is a super robot anime series by Toei Animation based on Hundred Demons Empire arc of Getter Robo manga by Go Nagai and Ken Ishikawa. This direct sequel to Getter Robo was broadcast on Fuji TV from May 15, 1975, to March 25, 1976, with a total of 39 episodes (some episodes were rebroadcast, erroneously giving the impression that there were 43 episodes).

Mattel's popular Shogun Warriors toy collection included Getter Robo G's robot formations in that toy line: Getter Dragon (Dragun), Getter Liger (Raider), and Getter Poseidon (Poseidon). As a result of the popularity of these toys in the US, Jim Terry included this series in his Force Five anime lineup under the title of Starvengers. Some Starvengers episodes were re-dubbed and released by FB Productions under the Robo Formers title. The original Getter Robo series, however, has yet to appear in the US (although the Shin Getter Robo OVAs have appeared). In the UK, Starvengers episodes were released on video by Krypton Force under the name Formators.
