There are seven different characters you can play in Temple Run, including Guy Dangerous, the starting character. But if you think you can get an advantage on the leaderboards by unlocking one of the characters, think again.
There are no differences in characters in Temple Run other than the obvious cosmetic differences.
For the player trying to maximize their advantage, characters are best left unlocked until you unlock all of the powerups. You can also spend your money on single use utilities, which will do you more good than unlocking characters. But once you have the powerups unlocked, unlocking the characters can be a nice goal to keep you going.
