4 Incredible Returns or Debuts that took place on Raw after WrestleMania

The Monday Night Raw after WrestleMania is always one of WWE's biggest and wildest events with the company pulling out all manner of shocks and surprises in order to begin new storylines and freshen things up after 'The Showcase of Immortals'.

some of the biggest things we were treated to was a WWE and Universal Title unification match between Kofi Kingston and Seth Rollins, an impromptu Intercontinental Match, a Raw Tag-Team Title match and the in-ring return of Alexa Bliss.

But that wasn't all! Not by a longshot! We were also treated to a large number of WWE Superstar returns and even some main roster debuts. But which familiar faces made their presence on Raw known yet again? And which new faces have we been introduced to?

Here are all of the big post-WrestleMania Raw debuts and returns!

#4. Lars Sullivan

Lars Sullivan was one of the standout stars of NXT with his uniquely grotesque look and imposing size, meaning it was certainly no surprise that he was earmarked for a main roster callup, signposted by vignettes that aired on Monday Night Raw.

However, Sullivan's main roster callup was postponed as the Superstar allegedly suffered from real-life panic attacks and as a result had to take some time away from WWE that ended up cancelling the future booking plans WWE had for him at WrestleMania.

With that in mind, no-one would have expected him to actually appear on Monday Night Raw the night after WrestleMania and attack 'Olympic Gold Medalist' Kurt Angle in what might be his last appearance for WWE. But that's exactly what happened.

One thing's for certain, Lars Sullivan is certain to be a dominant force on the Raw brand!

#3. Sami Zayn

The crowd went nuts when Sami Zayn was shown making his way to the ring from backstage and then even more nuts when the previously injured Superstar made his way to the ring and reintroduced himself.

They went even crazier than that when Finn Balor answered Zayn's open call for a match and then the match was turned into an Intercontinental Title match. Balor and Zayn put on a fantastic match for the post-WrestleMania Raw crowd but Balor eventually retained his title.

What the crowd didn't like, and almost certainly weren't nuts for, was Zayn's post-match promo saying that the WWE Universe was toxic and that it was his job week-in and week-out to hold the crowd to account for their actions.

Zayn even told the crowd he would see them in hell as he made his way out of Monday Night Raw a heel when he entered as a face.

#2. Mojo Rawley

It looked liked Mojo Rawley was about to make his return as a singles competitor on RAW after a series of vignettes aired of Rawley sat in front of a mirror talking about no longer being a team player.

To be honest they were pretty good promos and I was excited to see what would happen when Rawley debuted but as WrestleMania got closer somethings had to give way for the 'Mania build-up storylines and Rawley's promos and re-debut seemed to get put on the backburner.

However, this Raw, they debuted a new vignette and Rawley seems closer than ever to making his in-ring return with a character completely different to what we're accustomed to from the former 'Hype Bro'.

#1. The Undertaker

In hindsight it should have been obvious when Elias said that if anyone interrupted him on Monday Night Raw then he would 'give them hell' but it wasn't until the rather on the nose 'dead man' reference drop that the Raw crowd realized what was about to happen.

And then that iconic gong rang out, The Undertaker's entrance started playing and the 'Phenom' himself emerged from the darkness to send the crowd absolutely loopy. 'Taker then made his way to the ring and Elias decided it was a good idea to try and attack 'Taker. It wasn't.

The 'Deadman' proceeded to devastate Elias with his litany of iconic and familiar moves and then he made his way back out of the arena. We may have had our first 'Mania in years without Undertaker, but it seems his time in WWE isn't over yet!
