You guys are funny. Remember, you need to have explainations with it!
Top Tier:
Fox - Speed and Agility. Fox can move fast and pull off attacks in any direction quickly.
Kirby - If you don't KO Kirby, he will get back on stage and stone you.
High Tier:
Samus - In my CPU experience, Samus has typically lasted the longest when I play against 3 Level 9 CPUs
Luigi - Good jumping and power
Ness - Powerful and annoying attacks
Mid Top Tier:
Pikachu - Agile, but on the light side. If Pikachu's special attacks were a little harder to dodge, he'd be in the top.
Mid Tier:
Captain Falcon - Falcon Punch is powerful to land, but hard to land. Top Speed, but not the fastest attacks.
Mario - Mid of Mid Tier. Go figure

Yoshi - Slow attacks and movement, but high endurance and 2nd jump is difficult to stop
Low Tier:
Link - Worst jumping capability. Good attacks but slow, and a slow grab.
Jigglypuff - Worst endurance. Easily KO'ed before 100%, and no 3rd Jump.
Donkey Kong - Slow attacks and easy to hit. Relatively weak (%wise) grab, and easy to KO when there is no land under him.
