#2. Suprise returns/debuts

WrestleMania is known as a worldwide spectacle for a reason. Millions of people tune in to watch the event every year because it is one of WWE's most unpredictable shows. Over the years, we have seen a lot of Superstar returns and debuts on the show.
This year's event could be no different. Last year we saw the return of the 'Doctor of Thugnamoics' and the year before that we saw the in-ring debut of Ronda Rousey. There's no denying that a Superstar returning to no fans in attendance will be odd and lackluster, but to keep the spirit of WrestleMania alive, WWE could go all-in with it.

Superstars such as Nia Jax and Lars Sulivan, who have been absent from WWE TV for months, could make a return at the event.
According to Dave Meltzer of the Wrestling Observer Newsletter, Nia Jax is clear to return and it's just a matter of time before we see her again on WWE TV.
"Nia Jax has been medically cleared to return after reconstructive surgery on both knees. It’s just a question of when they want to start her back and where. Right now she’s earmarked for RAW, and not SmackDown as has been reported in many places."
Regarding 'The Freak' Lars Sullivan, Meltzer stated:
"Another name who should be ready but whose future is uncertain is Lars Sullivan. Sullivan underwent knee reconstruction surgery in June, so should be ready fairly soon. His name hasn’t been mentioned at all of late."
