The TNA Wrestler: Jeff Hardy
In recent years, WWE has become more open to cross-promotion appearances, especially with TNA. Well before the two wrestling companies struck a multiyear partnership earlier this month, TNA stars have shown up in WWE. At last year's women's Royal Rumble, then TNA Knockouts champion Jordynne Grace entered the match to the surprise of many. Now that the two companies have officially come together, the floodgates open up a sea of possibilities this year.
There are a few former WWE stars in TNA, like Nic Nemeth (Dolph Ziggler in WWE), who could make an appearance, but none more popular than Jeff Hardy. Hardy has held multiple single and tag-team championships during his 13+ years in WWE. At 47, this may be one of Hardy's last chances to be in the 30-man spectacle.
