Is it me, or Sanji (One Piece) is exactly like

?
KNT was a parody, so of course they where based on anime stereotypes...
One Piece uses many of those "cliches"...
A "leader" who is kind of dumb and loves eating (Speedy)
Also the leader becomes more powerful as the series goes on
A girl with brains, and that loves money (Francine)
A character who is "Handsome" and goes after girls... (Guido)
A coward (not seen in KNT, but seen in many other animes)
And so on...
Of course you are going to find many news animes that have characters similar to older animes, thats the way they do stuff in Japan..
