 "Gurren Lagann" occasionally pays homage to Ishikawa's "Getter Robo", particularly towards the end of the series, where the scale becomes absurd, with the robots steadily becoming bigger and bigger, much like "Getter Robo" more specifically, the manga version of Getter Robo Go.The final enemy also bears a striking resemblance to La Gooth of "Records of Nothingness", another work by Ishikawa.Nakashima, however, wanted to conclude the story of "Gurren Lagann" in a more reasonable fashion than what Ishikawa usually does in his works.
