Trivia

 * Jennifer Hale reprises Samus Aran for this episode. Jennifer had voiced her in Metroid Prime and its sequels Metroid Prime 2: Echoes and Metroid Prime 3: Corruption, albeit only grunts of pain heard when Samus is harmed, and heavy breathing when low on energy. In this episode, however, we eventually get to hear her talk, even when she tells the Star Teens to follow her lead.
 * Jennifer has also voiced Jessie Bannon on season 2 of The Real Adventures of Jonny Quest and Sam on Totally Spies, among other female characters of other TV shows and movies. Speaking of which, fans of The Real Adventures of Jonny Quest and Totally Spies will get to hear Samus who does sound like both Jess and Sam.
