#7 Ivory
WWE brought back several of the past greatest women's wrestlers for the inaugural women's Royal Rumble last year, including Trish Stratus, Lita, Alundra Blayze, Michelle McCool, Molly Holly and more, but one notable exception was former WWE Women's Champion and 2018 WWE Hall of Fame inductee, Ivory.
Now while it is true that Ivory is long since retired, back in 2006 to be exact, that hasn't stopped WWE from asking other retired stars to make cameo appearances in the Royal Rumble over the years. I think ivory deserves a spot in this years match as she is one of the all-time greats, a 2 time WWE Women's Champion and unlike a lot of women's wrestlers of the Attitude Era, could actually wrestle and didn't rely on her sexuality.
And as seen at the Hall of Fame ceremony last year, Ivory, who seems to have stumbled across the fountain of youth, is still in great physical condition and looks like she could have no problem lasting in the Royal Rumble for a few minutes.
