- The premiere of Abaranger was likewise the beginning of the duo which would eventually become Super Hero Time, a block of shows on Sunday morning on TV-Asahi pairing Sentai with it's partner franchise, Kamen Rider. This episode paired the first Abaranger with Kamen Rider 555 episode 4, My Name.
- While Asuka appears briefly as AbareBlack at the beginning of the episode before his transformation was reversed, this does not count as the Abaranger team had not formed yet. AbareBlack's official introduction to the team would take place in Ep. 7: Abare Baby Bakuryuu.
- While also the first opening episode with a "cold opening", this is also the first opening episode in Super Sentai where the regular opening credits do not play; while the opening theme is used, it is to footage of AbareBlack on Dino Earth. This will become a regular feature with opening episodes of many Sentai from here on, with the actual opening not used until episode 2.
- Pre-Credits Question: What is the mystery object coming that is making the ground shake?
- Answer: A massive, unknown Bakuryuu.
- Every episode of Abaranger has a "question" asked prior to the closing credits, with the "answer" revealed in a final scene after the credits but before the preview. In the first episode, there is no ending credits, so it's merely a brief commercial break prior to the final scene.
