Diana is a main character in the 1983 Marvel Productions Ltd., D&D Enterprises and TSR nonlinear animated series, Dungeons & Dragons. Diana is voice acted by Tonia Gayle Smith.
It's impossible to begin an analysis of a character as complex as Diana without considering the issue of race. Diana, like Ohura on Star Trek TOS, is a black female character among a white crew. Was this a purposeful attempt to try to balance a group that included two Aryan blue-eyed blonds? If so, the attempt was a farce. While more mature than the rest of the children intellectually and superior to any of them physically, Diana is never allowed to lead the group. She always ends up playing a side role as protector of the weaker party members and advisor. To make matters worse Diana comes out as an obvious sex symbol, wearing by far the least clothing of any member of the group - fur underwear and boots.
Diana is one of a group of children beamed into an alternate Dungeons & Dragons universe - the Realm. State athletics champion several years running (The Timelost) and daughter of an astronomer (Child of the Stargazer) she is armed by the diminutive Dungeon Master with an extending staff that increases the distance of her jumps. Diana frequently uses the staff to disarm opponents, pin open falling doors and hit farway objects by sending the staff whirling through the air at them. The staff can shrink to the size of a toothpick, though where Diana stores it with her sparse attire is never dealt with.
Diana frequently shows herself the others' superior, both in solving Dungeon Master's insidious riddles and in dealing with their frequent encounters with monsters and fiends. While Sheila comes across as skittish and nervous, Diana is confidant and adventurous. In the episode Quest of the Skeleton Warrior Diana is changed into a hagard old woman who must protect the infant Bobby from attacking monsters, and here her greatest fear of not being able to protect her friends is revealed.
Despite her strengths, Diana is a hopeless romantic. She falls in love twice during the series with quite improbable people, and both times the object of her affections is swept away to another world. In The Timelost she goes after Hans Mueller, a Nazi airman. Through her interaction with him he gives up his role as a member of the Third Reich, and when he returns to the normal world dedicates himself to fighting on the Allied side against Hitler. In Child of the Stargazer, Diana falls in love with an Arab by the name of Khosar. While Khosar is hardly a very interesting character, stuttering and bumbling his way through the Realm, Diana is prepared to sacrifice going home to help him get back to his own world, which, it is implied, is among the stars.
Indeed, Diana often sacrifices much for the sake of others. Together with Eric, she is perhaps the most active in defending other members of the group and saving them from their own mistakes. In Child of the Stargazer her efforts save an entire city, enslaved for a thousand years until her arrival.
Diana rarely talks about her home back on earth, and as the series goes by seems less and less concerned about whether she will ever get back there. A pillar of the group, they would certainly not survive as long in the Realm without her.
