* ActingForTwo: In the English dub of ''J'':
** Creator/ErinFitzgerald voices Cherry (3-13) and Luchs.
** Creator/NicoleOliver, who voices Baiko, later took over for Erin for the remainder of the series.
** Tamasaburo and Lorelei are both voiced by Ellen Kennedy.
* CastingGag: Otaru is played by Yuka Imai, who portrayed Junior, R's protagonist.
* CrossDressingVoices: In the Japanese versions of the series, Junior and Otaru are voiced by Creator/YukaImai.
* NoExportForYou: The ''Battle Sabers'' videogame.
* TheOtherDarrin: After episode 13, Creator/NicoleOliver replaced Cretor/ErinFitzgerald as both Cherry and Luchs in the English dub after Erin moved to the US.
** Also the ''J'' series ended up being dubbed by Ocean in Vancouver instead of Animaze in LA, so the entire cast was changed. Notably Otaru went from being voiced by a female (Creator/MonaMarshall) to a male (Creator/BradSwaile). Then ''J to X'' went to Blue Water in Calgary, presumably due to union issues, and the entire cast was changed once again.
** Bound to happen to Luchs now that Creator/YukoMizutani passed away.
* CastingGag: The entire Japanese voice cast returned in ''J'', despite ''R'' having none of the same characters (they are similarly named Expies), where as most dubs had little to none of the voice casts return.
** The U.S. release got J's Lime and Cherry, Maggie Blue O'Hara and Creator/ErinFitzgerald respectively, to play R's Lime and Cherry, even though one moved south a while back.
* MarthDebutedInSmashBros: Many people assume ''R'' to be a sequel due to this, as it was not released in America until ''2004''. The same year ''J to X'' was localized.
* NoDubForYou: The ''J'' VHS (not kidding) release in 1999 was sub only, even though ''J Again'', released around the same time, had a dub. Averted with the DVD release.
* WhatCouldHaveBeen: Apple was going to be part of the original series, but she was cut. She appears in the ''Battle Sabers'' game, anyways.
