John Leslie is a huge, black dragon who resides in a cavern two miles below the surface of the Earth. John Leslie is infamous for for causing widespread destruction and havoc (or as he refers to it, "ruckin' boiz up yeh") on his occasional visits to the surface- indeed there is a growing body of evidence that the attacks on the World Trade Center in New York may have been down to Leslie "dressed up in a plane suit so we wouldn't know it was him". John Leslie is not to be confused with Samuel L. Jackson, because they are completely different.
