In terms of sheer K.O. potential, I'd say...
1. Gigabowser (there's absolutely nothing to stop you from ****** evryone with this one)
2. Super Sonic (seemed really deadly at E 4 all)
3. Mario Finale (not that much damage, but it kinda drags everyone to an unavoidable death)
4. Super Dragon (those fireballs do 25% per shot and have some serious knockback)
5. Palutena's Army (attacks everyone, high killing potential)
6. Zero Laser (>60% +massive range , kinda lacking in knockback though)
7. Galaxia Darkness (41% + pretty much guaranteed kill on anyone at 30% or more)
8. Triforce Slash (>60% on one + big K.O power)
9. Great Ether (same as T.Slash)
10. Volt Tackle (hard to control, but inflicts great damage)
Screw the rest,![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Peach's and DK's are particularly disappointing, though.
