With one week left until "SummerSlam," the WWE Universe will be in a celebratory mood as the company celebrates Hall of Famer Hulk Hogan's 61st birthday on "Monday Night Raw" with many surprise guests expected to be in attendance.

Hogan has been teasing that he has invited his former New World Order (nWo) partners-in-crime, Scott Hall and Kevin Nash, to his party -- reuniting the nWo for the first time since "Wrestlemania 18." What other surprises will Hogan have in store for the WWE Universe?

The feud between Roman Reigns and Randy Orton continues to increase in intensity after Orton laid out Reigns for "stealing" his shot at the WWE World Heavyweight Championship. Reigns bounced back last week, taking out Kane in a Last Man Standing match that saw the "Devil's Favorite Demon" hand in his demonic mask to The Authority after taking the loss. What will "The Viper" do to kill Reigns' momentum with just days left until "SummerSlam" and what will become of the newly unmasked "Big Red Monster?"

Dean Ambrose outsmarted his former Shield partner Seth Rollins last week in their Beat The Clock Challenge to determine the stipulation for their bout next Sunday night. While Rollins believed he had an easy win tailor-made for him after former champion Rob Van Dam was replaced last-minute by Heath Slater as Rollins' opponent, Ambrose became such an irritant -- including desecrating Rollins' precious Money In The Bank (MITB) suitcase -- that he helped "the One Man Band" upset the 2014 MITB winner in their Beat The Clock Challenge match. With Slater's win, Ambrose got to choose the stipulation, annoucing Friday night that he was going with a Lumberjack Match -- in which WWE Superstars will surround the ring to make sure neither combatant attempts to escape the squared circle. Will Rollins use The Authority's resources to send Ambrose one last violent message before Sunday's match?

Stephanie McMahon is proving to be every bit as devious as her father and her husband as she prepares to step into the ring for the first time in over a decade against Brie Bella at "SummerSlam." McMahon laid out both Bella Twins last week during the contract signing last week, giving Brie a taste of what's in store for her Sunday night, including demonstrating her version of her husband's Pedigree finisher on both siblings. What will McMahon do with days left to demonstrate to Brie Bella that she has as much "ruthless aggression" as her father and husband?

The stage is set for the "SummerSlam" main event with WWE World Heavyweight Champion John Cena defending his title against Brock Lesnar -- the man who put "the one" in The Undertakers 21-1 "Wrestlemania" record earlier this year -- after Triple H, desperate to get the title off of Cena, made a deal with Paul Heyman despite past differences. Cena has defeated Lesnar as recently as "Extreme Rules" in 2012, needing to wrap a steel chain around his fist to beat "The Anomaly." But Lesnar enters this match a different man, with a meaner streak after breaking 'Taker's win-streak and brimming with an attitude of promising to leave Cena in a pool of his own "blood, vomit, and urine." Will fireworks fly early with both champion and challenger scheduled to show up on "Monday Night Raw?"
