Sonic Underground/Trivia


 * Cross-Dressing Voices: Jaleel White as Sonia. Oddly though, if one watches an episode of Sonic Underground, you can tell the voice Jaleel White uses when providing the voice of Sonia sounds inconspicuously identical to the high-pitched voice White used from his other (more) famous role as Steve Urkel.
 * Hey, It's That Voice!: Hey, that's Urkel as Sonic! And, oh, I know who's playing Robotnik! It's Gary Chalk, aka Optimus Prime and Grounder! Actually, Jaleel White, who plays all three siblings, has said that he uses his Urkel voice for Sonia.
 * Also Sonic's singing voice, Samuel Vincent, better known as Double-D in Ed, Edd 'n' Eddy and Athrun Zala in Gundam SEED (among many other roles).
 * Maurice LaMarche voices Sleet (imitating Peter Lorre) and Athair (imitating Sean Connery).
 * Non-Singing Voice: All three hedgehogs had three separate Voice Actors for the singing segments - Sam Vincent for Sonic, Tyley Ross for Manic and Louise Vallance for Sonia.
 * Talking to Himself: Yes, Jaleel White voices all three main characters.
