Dont bite my head of if this is in the wrong part of the forum or it should posted somewhere else. But herer is my ideas
Zoro.
One Sword Style.
Final Strike: Basicly he focuses all of his power into one final strike with Wado Ichi Monji.
Frankie.
Jet Punch: He has a Jet Dial installed in his arm and uses it for a more deadly punch.
Frankie Boxing. Strong Gatling: He attacks his opponent with a series of punches.
Nami.
Some Raigoh like attack: She generates a huge thundercloud and hurls down at her opponent.
