Victoria
Victoria, Tara, Lisa Maria Varon or however you know her, is one of the few women from the early-to-mid 2000s who has yet to make a return during the resurgence of women's wrestling in the WWE.
Her contemporaries like Molly Holly, Trish Stratus, Lita and Ivory have already made appearances within the last two years, so it is more than time for her to make an appearance in the Rumble.
She has stated that at 47, she'll be retiring from in-ring work this year. I don't think she has any bad blood with the WWE, but perhaps that could be why she hasn't been asked to return yet.
As Tara in TNA, she had good rivalries with the likes of Gail Kim, the Beautiful People and Mickie James, so her ability to go and perform isn't in question. It's time for her to return for a final WWE appearance.
