A group of kids were at an amusement park when they spotted a roller coaster named Dungeons & Dragons. They climbed into the cart and were soon rolling among fantastical beasts. Then something went wrong. They were flung into another world and chased by a multi-headed dragon, none other than Tiamat! Luckily, a diminutive figure appeared and provided each of them with a powerful magical item to aid their escape. They also met Venger, the essence of evil in this land and their ongoing nemesis. Can the kids find a way back to earth or are they doomed to live out their lives in this fantasy world?
Hank the Ranger. Armed with a magical bow, Hank was the leader of the group. As this is a kids' show, the energy arrows from his bow were generally harmless, merely knocking out enemies rather than killing them. He could also create a fireworks display.
Eric the Cavalier. Armed with a magic shield, Eric was the complainer. He was a rich kid who was always the voice of opposition. Whatever the plan, he didn't like it and let everyone know. Despite being a cavalier, he did not have a horse. Or a lance. Or a sword. However, his shield could reflect spells back at the caster, which was his most effective attack.
Presto the Magician. Provided a conical wizard's hat from which he could pull random spells, Presto was mostly hapless. His spells were just as often comically inept as useful. Nonetheless, the party always looked to him to bail them out of the latest crisis.
Sheila the Thief. Provided a cloak of invisibility, Sheila was the older sister of Bobby. She was always worried about her reckless brother, always warning him against rushing into danger. Her mode of attack was to lure someone into charging her and then go invisible; inevitably, the attacker would collide with someone else or a wall.
Diana the Acrobat. Provided a staff, Diana was actually a monk though that was changed to acrobat for the show. Yeah, it is pretty obvious she is supposed to be a monk too, though her outfit is peculiar. Dressed in a bearskin bikini with Wonder Woman accoutrements, she jumps, runs, and uses her staff to pole vault.
Bobby the Barbarian. Armed with a magic club, Bobby was always eager to run up and engage in battle with the latest monster. His club was wielded against the environment, causing earthquakes that knocked down opponents or toppling trees that fell on enemies. Again, this is a kids' show. Where the rest of the kids are teens, Bobby is 9.
Uni the Unicorn. The kids have hardly arrived in the world when a unicorn joined them, having fled from Tiamat. It immediately bonds with Bobby and becomes a source of bleating. However, like Lassie, Uni is often sent to go get help.
The allies and monsters changed from episode to episode, but some were regulars.
Venger. A bat winged and horned villain, he often arrived riding a nightmare and blasted away at the heroes with unidentifiable spells. His goal is to acquire the magic items that the kids possess and thus become all powerful. He frequently polymorphs into different forms, convincing the kids that he is an ally before revealing himself. Of particular note is that Peter Cullen - none other than Optimus Prime of Transformers fame - voiced Venger.
Tiamat. Somehow, the chromatic dragon is a regular for this low-level party. Despite the fact that both Venger and Tiamat are evil, they are enemies who will attack one another instantly, which always provides an opportunity for the kids to escape.
Dungeon Master. A diminutive bald fellow with a fringe of long white hair and a red robe, he provides cryptic clues as to what they need to do. He typically appears early in the episode to explain the basic plot and at the end to congratulate them on their success. He always vanishes before Eric can ask additional questions.
Back in the day, I had only watched a few episodes before abandoning the show. It was too much the kids show. Watching it today, it is fun and provides some background for the AI reboot.
