From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Angela (アンジェラ, Anjera; FUNimation "Angela") is a student.
Dragon Ball Z
Angela appeared in "Gohan's First Date". She was a fellow student of Son Gohan at Orange Star High School during the Great Saiyaman Saga. She had long red hair and wore contact lenses. Angela blackmailed Gohan, who was certain she knew his secret identity of being the Great Saiyaman, into taking her on a date in order to keep from revealing his secret. It was eventually announced that her bribe was actually the result of recently spotting him wearing teddy bear underwear. Afterward, Angela misunderstood that Gohan and [[[Son Videl]] liked each other (to their denial), thus she dumped him and fell for yet another boy, leaving Gohan embarrassed and humiliated.
Dragon Ball GT
Angela appeared in the crowd who listened to Mister Satan's doomsday announcement.
