Since the fighting styles made by this power are completely new, they may be impossible to learn, master, and/or replicate.
Unlike Modification and Mixture, however, the user isn't simply modifying or combining new fighting styles to form new ones, but instead is creating entirely new fighting styles either from scratch and/or a previous working foundation of attack ideas.

A talented martial artist, Shuken (Fist of the Blue Sky/Fist of the North Star) combined the Seito Gekken's knowledge of the human body's Keiraku Hikō pressure points with his ancestor's art of Hokuto Sōke no Ken...
...to create the Hokuto Shin Ken/Big Dipper God Fist, one of the greatest forms of assassination martial arts in fictional history.
Wanting his opponents to not suffer during death, Toki (Fist of the North Star) developed his own brand of the Hokuto Shin Ken, dubbed the Hokuto Ujō Ken/Big Dipper Humane Fist which could induce ecstasy instead of horrifying pain.
Raoh/Ken-Oh/King of Fists' Gō no Ken/Fist of Strength (Fist of the North Star)
A deadly fighter and pirate in his youth, Zeff (One Piece) would go on to create and master the Black Leg Style, a kick based fighting style that combines the elements of Brazilian Capoeira, French Savate and, Korean Taekwondo.
Based around the foundation of his Nitoryu/Dual Blade Style, Roronoa Zoro (One Piece) invented his own unique style of swordsmanship known as Santoryu/Triple Blade Style that uses three swords in varying styles...
...and while already a skilled master swordsman, he also invented his Mutoryu/No-Swords Style a style of unarmed martial arts based on his sword techniques.
Ostensibly developed by himself, Mugen's (Samurai Champloo) champuru kendo is based on breakdancing combined with his highly unorthodox swordplay.
Rejecting the orthodox fighting styles of kenjutsu, Katsuichi (Usagi Yojimbo) created distinctive and new techniques of almost unbeatable swordsmanship.
Having developed his swordplay to an incredible level since his youth, Killer B (Naruto) created a unique fighting style known as Acrobat...
...which allows him to wield multiple blades with unpredictable dexterity and versatility.

Peter Parker/Spider-Man (Marvel Comics) combined his bullying experiences, combat lessons from Steve Rogers, kung fu training from Shang-Chi, and his own spider-powers to create a new martial arts style, the Way of the Spider.
After his mutation, Fused Zamasu (Dragon Ball Super) created his Divine Hammer fighting style to take full advantage of his enlarged arm, able to produce powerful shockwaves and wind slashes with his punches.
