Paul Winchell in Seasons 1-5 and
Jim Cummings in Season 6) – An aged bear who is the Gummi Glen leader, caretaker of Gummi Bear knowledge and wisdom, and a modest
magician. He is somewhat forgetful with spells, speaking occasionally with mild
spoonerisms, and having a
fear of heights. •
Gruffi Gummi (voiced by
Bill Scott in Season 1 and
Corey Burton in Seasons 2–6) – Gummi Glen's grumpy and conservative craftsman and mechanic. He is the voice of reason and a sound strategist for the group, though his
perfectionism regularly becomes his downfall. •

June Foray) – the
matriarch of Gummi Glen, responsible for cooking for the group, housework in their home, and preparing Gummiberry Juice through the secret recipe passed down to her. •
Tummi Gummi (voiced by
Lorenzo Music) – An overweight Gummi Bear cub, and the eldest of the three in the group. He is relaxed, laid-back and easygoing, and harbors a great love of food, but has remarkable (if mostly hidden) technical skills and good comprehension, and often behaves impartially in disputes or acts as an arbitrator. •
Sunni Gummi (voiced by
Katie Leigh) – An excitable and naive preteen Gummi Bear cub who exhibits a keen interest in human culture and fashion rather than in Gummi history. •
Cubbi Gummi (voiced by Noelle North) – A young Gummi Bear cub, the youngest of the three in Gummi Glen, who dreams of becoming a knight. He is characterized as being adventurous and somewhat impetuous, but with an open-mindedness to finding solutions to problems he faces. •

David Faustino in Season 3;
Jason Marsden in Seasons 4 & 5 and
R.J. Williams in Season 6) – A young boy serving as a
page and
squire in Dunwyn Castle. He is courageous and good-hearted, is the first human to encounter the Gummi Bears, and befriends them as a result of possessing a Gummi medallion that he leaves with Zummi, becoming friends with Cubbi over time. •
Princess Calla (voiced by Noelle North) – A princess of Dunwyn, who is defiantly adventurous, capable of defending herself, despite her dislike of her circumstances and royal duties. She is friends with Cavin, and also becomes friends with Sunni after meeting the Gummi Bears during the first season. •
King Gregor (voiced by
Michael Rye) – The king of Dunwyn, characterized as a benevolent, brave, and good ruler for his people. Like most humans, he believes Gummi Bears are a myth, and thus does not know of their actions helping to protect his kingdom. However, he does discover his daughter's previously hidden fighting prowess towards the end of the series and is deeply impressed by her. •
Sir Tuxford (voiced by Bill Scott in Season 1,
Roger C. Carmel in Season 2 and
Brian Cummings in Seasons 3–6) – The highest ranking knight of King Gregor's court and his trusted friend, as well as Cavin's superior. Tuxford is characterized as being an old, jolly man despite being somewhat past his prime for battle. •
Duke Sigmund Igthorn (voiced by
Michael Rye) – A disgraced knight of Dunwyn, exiled for conspiring against King Gregor, who leads an army of ogres to attack the kingdom from his fortress of Castle Drekmore. He is characterized as a vengeful, power-crazed tyrant. A common element in stories he is involved in is his desire to find a suitable weapon for his plans, as well as capturing Gummi Bears for their Juice, especially the recipe required to produce it. •
Toadwart (voiced by Bill Scott in Season 1 and Corey Burton in Seasons 2–6) – A dwarf ogre, who serves as Igthorn's
illeist lieutenant and second-in-command, often nicknamed Toadie. He is characterized as being smarter than other ogres, due to his ability to read and write. Affectionately
sycophantic to the Duke, if only because associating with the Duke gives him some authority over the ogres, who otherwise casually abuse him for fun. •
Augustus "Gusto" Gummi (voiced by
Rob Paulsen) – An artistic Gummi Bear, stranded on a deserted island with his friend Artie Deco, a wise-talking
toucan (voiced by

Lady Bane (voiced by
Tress MacNeille) – A human sorceress of considerable power, who maintains her youth magically and desires all of Gummi Bear magic for herself. She resembles and is based on the
Queen from Disney's
Snow White and the Seven Dwarfs. •
Sir Thornberry (voiced by Walker Edmiston) – An aged Gummi Bear knight who acts as the caretaker of the otherwise isolated Gummi Bear city of Ursalia. His manner is eccentric by a probable combination of his extended isolation and
senility, but still capable within his mental limits. •
Ursa (voiced by Pat Musick) – The statuesque female leader of the Barbics, a barbarian tribe of Gummi Bears driven from their native lands by humans and are
scornful of orthodox Gummi traditions. She and her tribe take up residence in Ursalia at the Gummi Glen Gummies and Sir Thornberry's invitation. ==Episodes==
