The other lions can pretend to be the alpha males when Brock Lesnar is gone, but he instantly reclaims his spot each time he comes back to WWE.
Built like a comic-book villain and wearing a penetrating glare, it only takes Lesnar stepping through the curtain to have the fans' chests tighten, to have the audience expect a wake of wreckage to form behind him.
His aura, his history of violence and the WWE roster's lack of intimidating heels allow Lesnar to swipe everyone else aside and sit back in his throne.
On Monday's Raw, The Beast Incarnate returned and did just that.
Triple H began the show by saying that he was considering his options for who would challenge John Cena for the WWE World Heavyweight Championship at SummerSlam. He surveyed his choices throughout the night, which included Kane and Randy Orton.
Eventually, Paul Heyman and Lesnar sauntered to the ring and shook the chief operating officer's hand, and the SummerSlam title match was set.
While Heyman raved about his client's power to destroy, Lesnar stood there brooding. It gave the crowd a moment to soak up the scale of the match to come, to watch a beast pace before he charges at his prey.
Had Triple H gone with Orton or Kane, there would not be the same unsettling feeling when staring at them onscreen.
The roster boasts several men who could have a great match with Cena, but none of them feels as threatening to Cena as Lesnar.
None of those wrestlers' last match saw him pound The Undertaker into the mat and end his streak of 21 wins at WrestleMania. The image Lesnar left us with before his latest departure was the seemingly immortal Undertaker lying flat on his back while a stunned Heyman led Lesnar out of the ring.
Triple H's options before Lesnar's arrival on Monday night theoretically included the entire roster.
Fans knew better than that, though. Many had seen the video ad promoting Cena vs. Lesnar at SummerSlam before Battleground had begun. Others read on F4WOnline (h/t WrestleZone) and PWInsider that Lesnar was scheduled to appear on Monday's Raw and en route to Miami, respectively.
The choice was always Lesnar, but really there was no choice.
WWE's roster is heel-deprived. There are a number of rule-breaking folks around, but its store of intimidators and monsters is meager.
Triple H told Orton earlier on Raw that he was the front-runner. Orton is certainly capable of being a top heel, but WWE hasn't presented him that way as of late. He's been far too dependent on The Authority.
The audience would know that a Cena vs. Orton matchup would focus on Orton looking to get Kane, Triple H or anyone willing to tip the odds his way involved.
He has not been a predator in a long while.
Kane's monstrous qualities have been diluted as well. WWE has presented him as a hurdle heroes leap over rather than as an unstoppable force.
Bray Wyatt is the closest to Lesnar in terms of exuding an ominous aura.
Most of the unsettling things he has done, though, have come on the mic. He hasn't yet been allowed to be the destroyer that Lesnar has been. Memories of his loss to Chris Jericho and losing his pay-per-view series to Cena 1-2 are still fresh.
Lesnar's resume is more filled with broken chairs, bloody brows and men unable to stand after battling him.
The Beast Incarnate certainly hasn't gone undefeated since returning in 2012, but victory over him has been costly. The last time Cena and Lesnar collided, the former wore a smear of blood across his head.
Being part-time means that Lesnar is creating fewer memories. The ones he does leave behind, though, are vivid acts of violence. Bring up Lesnar's name, and one flashes back to him beating Triple H so badly in their steel cage match that The Game collapsed the next night mid-match.
One sees Lesnar breaking Shawn Michaels' arm and assaulting Big Show with chair shots all over again.
Couple that collection of macabre recollections with Lesnar's unequaled presence, and WWE need not rebuild Lesnar each time he steps back in front of the camera. He's already the king of the villains, plucking his crown from whoever held it in his absence.
That was evident in how the Miami fans treated him when he arrived in the closing segment of Monday's Raw.
Even though it was no secret that Lesnar was arriving, the arena erupted. When Lesnar's music hits, an electricity hits the air.
Fans' reactions on Twitter were telling as well:
Other wrestlers just aren't described that way. There is a unique energy created when Lesnar is on the hunt in WWE.
Perhaps his limited schedule is as big a key to that as his imposing build and uncanny physical ability. When not around each week, WWE has little opportunity to mar his image with moments of weakness.
He simply arrives, conquers, exits and repeats.
