Klingensmith

Nathan “C4” Klingensmith makes his Power Slap debut bringing a background in amateur boxing and professional wrestling, along with a determination to prove himself in the heavyweight division.

Born in Pittsburgh, Pennsylvania, and raised in Natrona Heights, Klingensmith spent five years training in amateur boxing before transitioning into professional wrestling in 2024. He considers stepping into professional wrestling one of the best decisions he has made, giving him another outlet for his competitive drive.

Klingensmith first pursued Power Slap in May 2025 when he participated in a combine. Already interested in the sport and its unique form of competition, he saw an opportunity to put his toughness to the test. After waiting for his chance to compete, he is now preparing to make his first appearance on the Power Slap stage.

“I was a part of the combine in May 2025 and have been patiently waiting for an opportunity.”

For Klingensmith, Power Slap represents an opportunity to take his athletic career further than he originally imagined. Rather than focusing on a particular ranking or immediate championship opportunity, his priority is to compete against the best and establish himself as a legitimate contender.

His debut comes against Pono “Da Hawaiian Assassin” Pau, an opponent Klingensmith believes he can outmatch through toughness rather than theatrics. While he respects the competitive environment, he has made it clear that he intends to let his performance speak for itself.

“I will prove I’m the tougher guy and I don’t need to put on a ton of theatrics.”

Outside of competition, Klingensmith has had his share of memorable experiences, including winning $15,000 on a scratch-off ticket, which he admits he spent in less than a year on a Dodge Charger and partying.

Now focused on making the most of his opportunity in Power Slap, Klingensmith hopes to eventually test himself against the heavyweight champion and establish his place among the division’s top competitors.

With boxing experience, a growing professional wrestling career, and his long-awaited debut finally approaching, Nathan “C4” Klingensmith enters Power Slap ready to prove he belongs.
