Top 5 possible storylines for Brock Lesnar's return to WWE in 2021

#3 Brock Lesnar enters the Royal Rumble, AJ Styles eliminates him to begin WrestleMania feud

Brock Lesnar vs. AJ Styles was a phenomenal match

Brock Lesnar has had fantastic chemistry with smaller competitors. "The Beast Incarnate" has had excellent bouts with AJ Styles, Finn Balor, Rey Mysterio, and Daniel Bryan in recent years. Currently, Styles isn't engaged in a feud on WWE RAW.

"The Phenomenal One" unsuccessfully challenged for the WWE Championship at the TLC pay-per-view event in December. Recently, Adam Pearce has booked him against the lower mid-card talents. Drew Gulak, Ricochet, and R-Truth have all lost to Styles on WWE RAW. With these victories, Styles has gained a lot of momentum in recent weeks.

Many fans consider Styles as one of the favorites to win the Men's Royal Rumble Match this year. But he recently lost a WWE Championship Match against Drew McIntyre. Plus, Styles is unlikely to feud with Roman Reigns due to Paul Heyman's presence.

Because Styles is one of the marquee names on the current roster, WWE should book him in a high-profile WrestleMania match. Brock Lesnar could be the perfect opponent for "The Phenomenal One." The popular Superstars previously locked horns in a Champion vs. Champion Match at WWE Survivor Series 2017.

The best way WWE could begin this WrestleMania feud is by booking Styles to eliminate Lesnar from the Royal Rumble Match. Memorable WrestleMania rivalries like Roman Reigns vs. The Undertaker began in a similar fashion. So an epic clash between Lesnar and Styles could begin on Sunday.
