The Ringleader is exclusive to set 8684, The Collectible Minifigure Series 2.
Minifigure Parts and Accessories
The Ringleader is composed of four main parts: hat, head, torso, and legs.
The hat is a standard black version of part 3878. I was surprised to learn via BrickLink that only 13 minifigures have worn this hat in the past.
The head print is similar to the Series 1 Magician, but this gent is a lot more excited by his profession.
The torso is red with red arms and white hands. The torso print gives the impression of a red coat with tails, a white vest, and large bow tie.
The legs are black with no print and white hips.
The accessory that comes with this figure is a white whip (part bb425). This part has only been available in reddish brown with two of the Prince of Persia sets.

Army Building Potential
The ABP for the figure is low - even if this figure is desired for Circus MOCs, there's only one ringleader per circus.
Feeling It Out
This one's going to be tough. The top hat and whip might be difficult to feel out, but they are your best bet.
The following are the secondary bar codes that can be found on the back of each bag which indicates the figure inside. The EU bar codes are shown on the left and the US bar codes are shown on the right. These bar codes come courtesy of Grogall. You can find a single pdf containing all bar codes here.
Official LEGO.com Bio
“Ladies, gentlemen and children of all ages, you will not believe your eyes!”
The Ringmaster loves being in the spotlight and running the show. He’s in charge of the entire circus, and he always makes sure to keep the tightropes tight, the sawdust fresh, the trapeze rings shiny and all the animals fed and happy.
To the Ringmaster, the best thing in the entire world is the sound of the audience cheering and clapping all around the big-top circus tent. That’s why he always does his very best to put on the most spectacular show possible – and to outdo the performance from the night before!
The Big Draw
The Ringleader is an obvious compliment to the Series 1 Clown. The biggest draw here, however, is likely to be the whip. Only available in two Prince of Persia sets, this style of whip is still relatively new. White seems an odd color (why not black?), but may still be of interest. Overall, this figure will mostly be sought to fill out a Series 2 collection.
