Trivia[]
- Keiichi Hasegawa is also the writer for the animated adaptation of Mega Man Battle Network, known as MegaMan NT Warrior (ja: Rockman.EXE), a series similar to Gridman the Hyper Agent in that both feature its titular heroes fighting in cyberspace to stop the villain-of-the-week from terrorizing the real world. When Hasegawa was offered the position of writer for SSSS.GRIDMAN, he acknowledged the similarities of said shows and assumed it would also be similar, but was surprised to see how different it was to the original 1993 series, instead thinking it was closer to Evangelion.[8]
