Kenpo Goroshi

Kenpō Koroshi (拳法殺し, The Destroyer of Fists); the name of Heart's anti-martial arts style. His huge frame could absorb external impacts and defeat different types of martial arts in this manner. It was said only Nanto Seiken could destroy him by slicing through flesh and bone. This was until Kenshiro used Hokuto Jūha Zan to destroy him.

In the original manga/anime, Heart had no special techniques and used his sheer weight and size to crush his enemies. However, his fighting style was embellished in the video games where he is a playable character, such as the Arc Systems fighting game and Hokuto Musou.
