Chapter 13

"Speed" (スピード, Supīdo, Tonari: 13) is the 13th chapter of the One-Punch Man manga series.

Summary
Hammerhead sends his men to attack Speed-o'-Sound Sonic, and has to watch as they are all decapitated by Sonic, narrowly avoiding being killed himself. He then smashes the ground causing a massive shock wave, which ultimately does nothing to Sonic who then taunts him from a nearby tree. Knowing where Sonic is now, Hammerhead throws a large boulder at Sonic who dodges easily, the boulder continuing on until it smashes the roof of Zeniru's skyscraper. As Sonic lands on the ground after dodging the boulder he narrowly avoids a second boulder aimed at where he was to land. He looks up and sees several more boulders flying at him and dodges them all. Hammerhead then shows up, pushing through several trees, and taunts Sonic. Sonic then notices that all the boulders have "conveniently" made a direct path from Sonic to Hammerhead. Hammerhead lifts another rock and taunts Sonic again, so Sonic gets in an attack stance and rushes forward. Hammerhead drops the rock and picks up and smashes a tree down onto the path he'd made, but is then hit in the back of the head with a kunai by Sonic who'd managed to get behind him. Sonic takes out his phone and calls Zeniru to confirm Hammerheads death, but looks back and sees that Hammerhead is gone. Hammerhead, managing to survive thanks to his thick skull, runs away through the woods until he comes upon Saitama.
