From the 3 Musketeers website:
"The personalities of the 3 MUSKETEERS® Brand characters are as follows:
Porthos - a man of the world. He's smooth and sophisticated and exudes self-confidence and personal style. He's a man of chivalry and honor. He's James Bond with a saber.
Athos - brilliant and brave but also clumsy like a nutty professor. He constantly finds himself in awkward situations because he doesn't watch where he's going. He's a scatterbrained hero with a heart of gold.
D'Artagnan - the leader of the trio. He's young and eager, always the first to charge into the fray. He's courageous, gallant and always wins the day."
