Darkness fell upon Raw SuperShow on Monday night and the WWE Universe couldn't be happier. The chilling return of The Phenom (not to mention the equally cool reception by Triple H) and the duel between animal-free eating habits and a substance-free lifestyle got social media savvy squared circle devotees to "check in" while checking out the action.

It's the day after Raw. Let's see what you thought ...

Undertaker returns to Raw

For nearly a year, WWE fans have been asking, "where is The Undertaker?" On Raw SuperShow, a series of ominous gongs harkened the reemergence of The Phenom after long last. It would appear the bell yet again tolls for The Game, who came face to face with the ring's grim reaper in a fashion not unlike one year ago when roles were reversed and Triple H wordlessly summoned Undertaker to a clash at WrestleMania. (WATCH) Just as WWE EVP and Interim Raw GM John Laurinaitis was about to be demoted on live TV, The Deadman stepped forth from the Netherworld to render a clear challenge to The King of Kings ... who simply walked away.

Is The Undertaker truly interested in a rematch on The Grandest Stage of Them All or did The Deadman actually just save Laurinaitis from being "future endeavored" by The Game? If it's all about WrestleMania, will the Chief Operating Officer - now a finely manicured, well pressed "suit" type - really be able to ignore the iconic, streak-bearing Demon from Death Valley?

@brogsxx: NO WAY!!! Undertaker is back, oh my freeeeking goddddddd!!! #Raw

@g00mee: OH MY...LOOK WHO'S BAACK ON #RAW !!! THE DEADMAN WALKING...THE UNDERTAKER IS BACK !!!! WOOHOOO....

@Scotty_McTweety: @WWERawGM Ironic that undertaker seems to have saved your job on #Raw from certain death.

@FixinAHole: #Raw thoughts Undertaker gave me chills at first gong! so it looks like a WM rematch why does HHH want to be a WM victim a third time

@jimbodude316: #undertaker #tripleh for #wrestlemania28. End the streak? I think so! #raw

@BabyGrlBri: I'm hoping Undertaker fights Triple H @ Wrestlemania for the Streak! I'm not having any doubts that Triple H won't beat him! @WWE #Raw

@TheBenjyGuzman: Wait... So undertaker is the new RAW GM? Haha! #Raw

@seventeenblack: Wouldn't it be fun it the Undertaker came back in a new role as the wacky GM? #wwe #raw

@ActionTilson: Wrong time for the Undertaker! Interrupting the segment of Triple H & John I wanted Laurinaitis to be shown being sacked! #WWE #Raw

@_bthurst: @WWE I can beat undertaker's streak #RAW

@GreezyAce: So I take it that John Laurinaitis is still running #RAW seeing as Triple H was interrupted by The Undertaker when he was gonna fire Johnny

@DebPeltz: Stare at the Wrestlemania sign..stare at Triple H...stare at sign...stare at Triple H...repeat #Raw

Vegan or straight edge?

While the WWE Universe stands divided in the rapidly approaching WrestleMania XXVIII collision between John Cena and The Rock, even more polarizing contention arose between vegans and straight edge sects of WWE fandom on Monday. Sure, WWE Champion CM Punk and World Heavyweight Champion Daniel Bryan squared off in a technical bout that made wrestling purists salivate. But aside from their Champion vs. Champion Match itself, the two sparred verbally while extolling the virtues of their respective lifestyles - the alcohol, tobacco and drug-free straight edge Punk and the vegan Bryan, who abstains from eating anything derived from an animal. In other words, "I'll have a ginger ale" and "hold the cheese," respectively.

The personal policies on consumption aside, their veritable dream match was as hotly contested as expected until Chris Jericho "trolled" harder than before by interrupting the bout, first assaulting SmackDown's champion and then leveling Punk with the Codebreaker. (WATCH) "The end of the world" class match, is more like it.

@27Dannielle: Loved the bit backstage Punk & Bryan talking about what a vegan is & what Straight Edge is :) #RAW

@Mari_ayvey: Both are best!! RT @WWEUniverse: #StraightEdge vs. #Vegan ... who you got? #Raw #WWE #BestInTheWorld

@ped14: Quote of The day. Im a role model. Im a vegan. D Bryan. Love it. @WWE #RAW

@SmoHawk: Vegan vs Straight Edge @WWEDanielBryan vs @CMPunk #OMG thank you wrestling gods! #Raw

@notPrecious: Well, looks like @IAmJericho is neither straight edge, or vegan. #RAW @WWE

@HaydzzP: Daniel Bryan's a Vegan who wrestles... His diet must be very unique #Raw

@AllAboutARy: C'mon Punk, beat this #Vegan. #RAW

@WWECapshuns: LOL Bryan = Vegan Punk = Straight Edge. Commercials: Popeye's Chicken and 5-Hour Energy #CompleteCorporateDisconnect #RAW

@rybask: Champion vs. Champion? Will the vegan powers overcome Punk and that Pepsi tattoo? #raw

@Garytt: Champion vs. Champion. Straight Edge vs. Vegan. @CMPunk vs. @WWEDanielBryan. I'm gonna enjoy watching these guys show how it's done! #RAW

@nacgator: I am not straight edge nor am I a vegan. I got nothing here. #Raw

@mattsetsfire: Okay CM Punk wipe the mat with Daniel Bryan. Because straight edge is better than you, Daniel Bryan #raw #WWE

@MadnNeS12: Wow what a show I love it I love taker return and jericho attacking punk #Raw @WWE

@RobL17: #RAW was great last night. Jericho attacking D-Bry & Punk, The Undertaker & HHH returning, @WWERawGM still has a job, all good!
