Oba Femi and Brock Lesnar are set to settle one of WWE's biggest rivalries of 2026 inside Hell in a Cell at SummerSlam. After having a victory over each other in their first two encounters, the trilogy now heads into the company's most unforgiving structure.

The stipulation makes the bout even more significant because Brock Lesnar remains undefeated inside Hell in a Cell. If Oba Femi becomes the first superstar to beat him inside the Cell, it would be far more than another marquee victory. It could reshape WWE's main event scene for years to come.

That said, in this article, we look at four massive ways that historic win could change the company forever.

Oba Femi already looks like one of WWE's most dominant stars. Since his rise from NXT, he has consistently been presented as an unstoppable force. Also, his rivalry with Brock Lesnar has only strengthened that image.

However, defeating Lesnar inside Hell in a Cell would elevate The Ruler into a completely different category. Few accomplishments in WWE history compare to ending a legend's undefeated streak in a signature match.

Lesnar has built his reputation by conquering nearly every challenge imaginable. Thus, making an undefeated Hell in a Cell record one of the last untouchable parts of his legacy.

If Oba Femi ends that streak, WWE instantly creates a top superstar. Rather than simply being another powerhouse, he would become the company's new measuring stick. The superstar every future main eventer would have to overcome.

SummerSlam isn't just another match between these two. The rivalry currently stands at one win apiece. Oba Femi shocked Brock Lesnar at WrestleMania 42, while The Beast responded by defeating him at Clash in Italy. That makes Hell in a Cell the deciding chapter.

If Oba wins, there would be little debate about who emerged as the superior competitor. More importantly, it would become Brock Lesnar's ultimate torch-passing moment. Losing for the first time inside the Cell would represent the clearest possible sign that WWE's next dominant attraction has officially arrived.

Rather than hurting Lesnar's legacy, it would enhance Femi's. Passing the torch only works when the new star defeats a legend at their best. Thus, there is no bigger stage for The Beast Incarnate than Hell in a Cell.

RAW has gradually begun embracing a younger generation of dominant athletes. Oba Femi is at the center of that movement.

Defeating Brock Lesnar inside Hell in a Cell would immediately change the balance of power. Instead of Lesnar being the benchmark for physical dominance, Femi would become the superstar every powerhouse is compared to.

Future rivalries against names like Bron Breakker or even World Heavyweight Champion Roman Reigns would instantly feel bigger because of what he accomplished at SummerSlam.

Also, the victory would send a clear message that WWE is committed to building new attractions instead of relying on established legends to carry the brand. That kind of shift would define RAW's main-event picture for years.

Ironically, Oba Femi's biggest victory could also become WWE's biggest creative challenge.

Once someone defeats Brock Lesnar inside Hell in a Cell, they immediately become one of the most protected stars in the company. Triple H would have to be extremely careful about how it books Oba afterward.

The company couldn't afford to cool The Ruler off with unnecessary losses or inconsistent storytelling. Doing so would diminish the importance of ending one of WWE's most impressive records.

That doesn't mean Femi should never lose. Instead, every major defeat would need to feel meaningful. His aura should remain intact, just as WWE protected Lesnar's for years.

If booked correctly, Oba Femi could become the defining monster of this generation. A superstar whose presence alone feels like a major event. However, if WWE rushes into 50-50 booking or sacrifices his momentum for short-term stories, the impact of breaking Lesnar's Hell in a Cell streak would quickly fade.

That's why this match could change the company forever. It wouldn't simply crown a new dominant force. Perhaps it would force the company to rethink how an "unbeatable" superstar should be booked in the modern era.

If Oba Femi becomes the first man to defeat Brock Lesnar inside Hell in a Cell, WWE must protect that accomplishment and build around it. Thus, ensuring the historic victory becomes the foundation of a new era rather than just another memorable SummerSlam moment.
