Dellinger is one such character that uses kicking as his fighting style. As from one-piece wikia.
Dellinger is a combatant and an officer of the Donquixote Pirates' Diamante Army. He is a hybrid between a Human and a Fighting Fish Fishman.
A human-fishman hybrid, Dellinger was born physically stronger than the average human, going by his ability to lift cannonballs at two years of age without problems and the fact that full-blooded fishmen are supposedly ten times stronger than humans, but it's unknown if he's as strong as an average fishman in relation to a human
Dellinger is extremely proficient in kicking, seen when he easily knocks out Blue Gilly, a powerful martial artist known for his own strong kicking, with a single kick while leaving no time for the latter to react. His kicking strength is further highlighted by the fact he is able to kick and move Machvise, who at the time weighs 10 tons thanks to his Devil Fruit, though Dellinger shouts in pain a result of the kick.
Pistol High Heel (ピストルハイヒール Pisutoru Haihīru?): Dellinger rushes towards to his enemy and kicking him with force while wearing high heeled shoes. It is powerful enough to hurt even super-weighted humans. It's first used accidentally on Machvise.
Danto High Heel (断頭ハイヒール Dantō Hai Hīru?, literally meaning "Decapitation High Heel"):- Dellinger charges at his enemy and unleashes a hard kick to the neck, potentially strong enough to cut an opponent's head off given its name. It's first used against Blue Gilly and is powerful enough to take him out in one blow.
