In old cartoon "Dungeons & Dragons", Uni is a filly unicorn who the heroes meet when she is fleeing from an angered Tiamat. Afterwards she befriends the heroes with Bobby adopting her as a pet, and retains as his companion throughout the show.
Uni has the ability to speak, though her words are not quite discernible; she usually is heard echoing Bobby when she agrees to his opinions. As seen in the episode "Valley of the Unicorns", Uni also possesses the potential for the natural unicorn ability to teleport once a day, and has accessed this power through tremendous concentration and effort; it is intimated that she is still too young to use this ability regularly—without her horn she cannot teleport and becomes very weak.
The Series Bible describes Uni as being like a bloodhound who sniffs out trouble, and she tracks Sir John in Eye Of The Beholder and helps Freddy the dog sniff out breakfast in The Girl Who Dreamed Tomorrow. Uni also displays suspicious behaviour towards the evil Karena in the Citadel of Shadow and Venger disguised as a flying warrior in The Last Illusion when the other heroes are oblivious. In the City At The Edge Of Midnight Uni wakes just before midnight as if sensing the arrival of the Nightwalker.
In the Quest Of The Skeleton Warrior Uni casts no reflection in one of the magical mirrors that reflect the viewer's fear. This could imply she has no deep-rooted fear to exploit or that being a unicorn she is not eligible to become a Celestial Knight so the mirror ignores her presence, reflecting nothing instead.
In the Maze Of Darkness she is unaffected by one of the hypnotic light traps that make people attack each other.
A common misconception is that the kids never make it home because Uni always got into trouble and had to be rescued at the expense of the portal to the amusement park closing. This never happened in any episode. On two occasions Bobby was reluctant about returning to the amusement park because it would mean leaving Uni behind but his reticence was never at the expense of a portal's time frame (The Eye Of The Beholder and Day Of The Dungeon Master). Uni even followed the kids home into the amusement park briefly before returning to the Realm with them (Beauty And The Bogbeast).
However, despite never preventing the heroes from returning home Uni has caused them quite a few problems. In The Night Of No Tomorrow she wakes an angered Tiamat while testing a mountain's echo properties. In The Eye Of The Beholder she unearths a giant scorpion that attacks the heroes and later on makes Bobby sneeze by brushing her tail against his nose and causing him to blow out the candles on a birthday cake that is providing an illuminating defence against the snail people. In P.R.E.S.T.O Spells Disaster, startled by a drunk, Uni leaps through a window and into a tavern where she is captured by a three-headed ogre. In The Treasure Of Tardos Uni sneezes and alerts an army of orcs although Eric was responsible for kicking up dust and causing her to sneeze. Uni is especially unhelpful in The Box when the exhausted heroes are hauling Zandora's boxto Skull Mountain she is acting as a reverse pack mule and sitting on top of it, adding to the weight, and earlier on she alerted the heroes to the illusory Skull Mountain trap. The vocal effects was provided by Frank Welker. _____________________________
