Oh, the LULZ! A National pastime,huh? As for Trafalgar Law I copied this from the OP wikia:
Law is an extremely laid-back character, who is nearly always seen smiling (although not with a huge grin). He also has a more reckless attitude when faced against other pirates that the World Government has labeled as a higher threat. For example, he casually asked X. Drake how many people he had slain in his very first appearance, and had no qualms about flipping off Eustass Kid, the most wanted Supernova on the Archipelago (even smiling defiantly when doing so). However, he hates being ordered around, as evidenced of his frown and following reply when Kid told him and Monkey D. Luffy to stay back as he would hold off the attacking Marines. He is, however, capable of knowing when he and his immediate Crew are in a pinch, and is not above resorting to forging brief alliances with rivals for survival. He speaks in a politely sarcastic manner and usually refers to others as "Mr". He appears to be honorable enough to refuse taking credit that is due to others. This is seen when he replied to Jean Bart that his gratitude is also deserved by Luffy when the former slave offered his gratitude to the Pirate Captain.
Law has displayed a more competitive side about him in the anime where he, along with Kid and Luffy, got into a childish argument about who gets to take down the marines stationed just outside the Human Auctioning House when the three Supernovas came out to confront them. In contrast, he does not seem as eager to reach the New World as the other Supernova crews are, believing that One Piece will still be there regardless while the other crews fight amongst themselves, and that he needs to steal the throne "properly".
Law also appears to have a sense of honor (or at least respect for those he sees as potential rivals in the future), which is seen when he appears at Marineford and claims he will help Luffy, because it would be "too lame" if his future enemy were to die there. This is in stark contrast to what most people seemed to think about him, since Scratchmen Apoo claimed that Law was infamous for his cruelty.
Law is also very blunt when responding to people. Such occasions include when Ivankov asked if Law was a friend of Luffy, to which he replied "no," and even offered to make an excuse to make Ivankov feel better about him saving Luffy. Soon after, a wounded Jinbei went to thank him, only for Law to replied that if Jinbei didn't sleep, he was going to die. Another occasion was when Jinbei asked what would happen to Luffy if he was allowed to run rampant while still wounded. Law simply replied that the outcome was simple; Luffy's wound would open up and he would die.
It seems to be a pretty thorough description. He's damn cute too, see here: http://images2.wikia.nocookie.net/__cb20090329192412/onepiece/images/3/38/Law.PNG?iact=hc&vpx=135&vpy=111&dur=1676&hovh=221&hovw=228&tx=115&ty=144&ei=MkjKTNKOH4Sq8AaF7tT0AQ&oei=40fKTJfTOMP7lweso4WRAQ&esq=7&page=1&tbnh=156&tbnw=161&start=0&ndsp=10&ved=1t:429,r:0,s:0
He's got a really weird DF ability. He can create a "room" and within this territory, he is capable of separating and spatially displacing anything and everything inside. With his powers, he is capable of making it seem like he can swiftly slice people up into pieces from a distance with his sword. He can also attach separated parts in any manner he sees fit, such as sticking someone's head to a barrel. People separated by this ability aren't killed, and can still feel their separated parts, regardless of the distance they were separated from each other (much like Buggy when he separates himself using the Bara Bara no Mi). The effect persists even after Law disengages the sphere. How, or even if, the separated parts can be reassembled is unclear.

So yeah. He's a really interesting character.
