- This is the last of three consecutive opening episodes (preceded by Ep. 1: Hurry! Save the Earth and Ep. 1: The Mysterious, Beautiful Runaway) where the team has access to their powers from the opening of the first episode; however one difference in this scenario is due to the Livemen having their power only after a time-skip to the present, with the series starting with a flashback.
