Captain has a large advantage over all the other Smash characters, he's the fastest.  Almost 1½ times faster than Fox.  This means he can get in to and out of the action quicker than other players.  That and his bicycle kick in the air is devastating.  His only real setbacks are his slow recovery from "B" moves, and his lack of a long range weapon.  After using his B moves he is very vulnerable, and a hit and run technique is best against him.  You don't want to get too close, or he'll ruin your day.  Above average jumping hieght.
