Braggio Ironhook was a big, loudmouthed ferret with a hook replacing his missing left forepaw. He was ambitious and vain, and challenged Razzid Wearat for captaincy of the Greenshroud. He was also more intelligent than most vermin - even Razzid noticed this - and it was he who came up with the idea to fit wheels and giant crossbows on the Greenshroud.
