8. Batista
Batista takes the lowest spot on this list because of his obvious film commitments (with work on 'Guardians of the Galaxy 2' set to commence soon), but
news reports already indicate that Vince has been keen to draft The Animal in for a surprise WrestleMania appearance. If WWE
are able to secure the former champion's services, he could well announce his arrival this Sunday. Although it's probably unreasonable to expect him to slot neatly into a bustling main event scene, there could be a place for him in the feud between The Wyatt Family and the assorted gigantic babyfaces. Should the Wyatts take out Show, Kane and Ryback at Fastlane (as you'd expect them to do), maybe a post-match run-in from The Animal could remind everybody that WWE still have plenty of "titans" in reserve.
