Which Dragon's Den investor was known by the nickname “the Scottish Dragon”?

Duncan Bannatyne was known by the nickname “the Scottish Dragon” on the British show Dragon's Den.

Bannatyne is a Scottish entrepreneur, philanthropist and author who became one of the programme's best-known investors. He built businesses in areas including health clubs, care homes and hospitality before joining the television panel. His accent and Scottish background made the nickname an obvious part of his on-screen identity.

On Dragon's Den, Bannatyne was associated with direct questioning and a willingness to challenge entrepreneurs over ownership percentages, profits and business plans. His television role made him widely recognisable beyond the companies he had built, while the nickname helped viewers distinguish him from the other Dragons.

The phrase should not be mistaken for an official title or a separate programme. It was a descriptive nickname used for Bannatyne within the Dragon's Den context. Peter Jones, Theo Paphitis and James Caan were also Dragons, but they are not the investor identified by this particular nickname.
