SO HERE'S WHY NESS BEATS KING DEDEDE

Ness beat Giygas, who is like, 2-C. And Ness has craptons of experience fighting baddies, so I'm sure a penguin with a large mallet won't be any problem. Dedede is likely around MSS level, while Ness is at Galaxy Level, surpassing him. Plus, via Smash Logic, PK Fire spam can murder King Dedede. Also Dedede can't even compare to Galaxy Level Backthrows, making Ness easily obliterate him in that category, alongside taking nearly every other advantage he could have. Plus, while King Dedede could eat Ness' attacks, Ness can just get up close with the baseball bat, and then while his foe is down use PK Attacks to really punish Dedede for good.

And this is my legit reasoning to why Ness > Dedede.
