Roman Reigns gave WWE fans something to cheer about when he re-emerged on WWE Raw last Monday. The Big Dog said he is under remission from leukemia and showed towards the end of the show that he can still get physical if he wanted to. 

Reigns joined hands with Seth Rollins to help their Shield-brother Dean Ambrose who was being ganged up on at that segment. The former WWE Universal champion showed he still had his vicious Superman punch, although this may not totally indicate that he is well and good. 

Considering it was only October of last year where he revealed his fight with leukemia, it would seem odd to see him back in harness in such a short span of time. While he may be ready to mix it up, there are other health conditions to consider. He may compete but only to a certain capacity -- a reality when it comes to the WWE. 

At any rate, seeing the Big Dog at Wrestlemania 35 could be something. If he is well enough to be in a match, finding a proper opponent at this point would be like looking for a needle in a haystack. John Cena, another WWE star who has yet to have an opponent in the grandest stage of them all, could be a potential opponent, Comicbook.com reported. It all falls on the hands of the WWE scriptwriters.

Ironically, both Cena and Reigns have been spending a lot of time in Hollywood. Cena has appeared on several films, while Reigns is set to make his film debut on "Fast and Furious: Hobbs and Shaw," Comicbook.com reported. An appearance by Reigns at Wrestlemania 35 could be a big boost to help promote the film -- meaning his match could be made with no big stakes on the line.

Reigns could simply be around and make an appearance. He could also plant seeds for his return, meaning he could take aim at Brock Lesnar. Rather than a physical encounter, he could play mind games with the Beast Incarnate. So far, Lesnar's opponent remains unknown although it could be Seth Rollins.

Assuming the King Slayer is able to defeat Lesnar, Reigns could get involved for an assist. To announce his return, a heel turn could happen -- potentially payback to Rollins who screwed Reigns back at Wrestlemania 31
