Smokey alongside with his partner Blood are bandits who came to Carona just like everyone else to find the Relic.
Smokey appearance may seems threatening but just like Blood they're nothing but cowards. Smokey is the brawn while Blood is the brain. In a battle it doesn't matter which one is first defeat, if one is the other will escaped as well.
Blood & Smokey kidnaps Elena in order to forced her father Klaus to tell them were the Relic is, however in both stories Mint and Rue saved her causing the dual to fight them. The bandits are defeated easily and runs away.
Later in the story they work for Trap Master and seemed confident that this time they'll win, but they are proven otherwise.
