Sir Gawain, Cavin's grandfather, who also originally found the Gummi Medallion which Cavin had been wearing until he gave it to the Gummi Bears. He is highly idealistic and loves to tell moral fables of the ancient Gummis on every suitable occasion. He has met the Bears of Gummi Glen, but he is unaware that Cavin knows them as well, although he has said that he is confident Cavin will meet the Gummi Bears. When Sir Gawain saw that Zummi was wearing the Gummi medallion he had given to Cavin, he was glad it was in the right hands. Most likely named for the knight of the Round Table in the Arthurian legend, though it is possible that he is meant to be the same character.
