The 30-second promo starts with a voiceover of Seth Rollins calling himself the future of the WWE and delves into Michael Cole dubbing Lesnar as The Beast Incarnate on commentary.

"A destroyer locked on his target," the teaser's voiceover says. "Brock Lesnar, Seth Rollins, the WWE World Heavyweight Championship. WWE Battleground."

Lesnar and Rollins are on a collision course that truly began at WrestleMania 31 in March, when The Architect became the first man in history to cash in his Money in the Bank contract at the Show of Shows.

Rollins crashed The Beast's title defense against Roman Reigns that night at Levi's Stadium in California, leading to the bout becoming a Triple Threat Match.

The former Shield leader then hit Reigns with the Curb Stomp, winning Lesnar's title without even pinning him.

It ended a dominant run through the WWE for Lesnar, which saw him end The Streak of The Undertaker at WrestleMania XXX and then decimate John Cena to capture the gold last August at SummerSlam.

Lesnar and Rollins were also involved in a Match of the Year candidate in a Triple Threat Match for the richest prize in the game, which also involved John Cena, at the Royal Rumble in January. Lesnar won that match to retain his title.

It's The Beast vs. The Architect live this Sunday night when the WWE presents Battleground from the Scottrade Center in St. Louis.
