Garundel was an Urodelian who crash-landed in Denmark in the fifth century. After meeting Beowulf and Weohstan, he became the inspiration for the monster Grendel in the epic of Beowulf. This was also when he first encountered the Seventh Doctor. (AUDIO: Black and White) They met again when the Doctor and his companions went to Garundel's auction to steal the Persuasion machine and the preserved body of its creator Kurt Schalk. He used the machine to persuade the Sontarans and the other races at the auction to give up the weapons and their money. Arrogant in money-driven to the point of lunacy, he cold-bloodedly murdered Ziv for what Elizabeth Klein described as 'wounding [his] pride'. He was tortured by Marshal Stenn and his hand removed to remove the lock on the Doctor's TARDIS. He was working with the Daleks, so that they could capture the real Schalk.

Garundel began running a con where he would crash into other ships and make the other party take the blame for the "accident". He crashed into Jenny's ship, and led her to a spaceport where his partner Vesh Taralesh told her the ship was a right-off. Jenny escaped from Garundel by stealing another ship. Garundel and Vesh set off in pursuit of her, finding out that from her species she would be worth much more alive. When COLT-5000 turned up to capture Jenny, he tried to ally himself with her to spare his life. At first the bounty hunter was uncooperative, but when Jenny escape through time, Garundel offered a way to track her, thus escaping with his life. (AUDIO: Stolen Goods)
