Albee Stewart is Dex's adoptive Earth brother. Albee looks up to Dex with enthusiasm as any little brother would. He tries to help Dex get accustomed to Earth by encouraging him to watch a great deal of television. Of course, Albee's help can sometimes lead to Dex acting strange in public.
In one episode, he dreamt that he gained the Masked Rider's powers upon bumping into Dex. He is able to transform in to the Masked Rider when Albee yells out the phrase, "Ectophase Activate!". In his dream, Count Dregon put Albee through a triple death match against three tough Insectivores, but Albee managed to destroy them all.
