Mach Punch (マッハ突き, Mahha Tsuki) is a special fighting technique of Katsumi Orochi.
Katsumi aligns his joints perfectly to deliever a punch or punches that break the sound barrier. He later refines this technique using Kaioh Kaku's suggestion to imagine that his body is made of thousands of joints, which make it so fast that his hand can cut an egg just like sword. But after he managed to broke the sound barrier with this technique, Katsumi's hand was greatly damaged. Katsumi used it against Kaoru Hanayama in the Maximum Tournament and Pickle in the third series of the manga. The ultimate form of this technique is Hitless Blow.
