Jillian Michaels replaced Henderson in the later part of the Cell arc, while his adult version is voiced by Brad Swaile.
Henderson believed her experience playing Goku in Dragon Ball made it simple to develop Gohan's voice, though stressed performing as him was "tiring" due to the action of the series requiring louder volumes.
Nozawa, who also voices Goku, revealed that she did not know she would be playing Gohan until receiving the script on the day of recording his debut episode.
Henderson reprised her role in AB Group and Westwood Media's alternate dub for the UK and Canadian markets in 2000.
Ever since this fight, Gohan has given up on fighting and has continually gotten weaker to the point that he can't use his Super Saiyan transformations without straining himself.
