With the WWE's Brand Split on the horizon, the Universe is full of speculation about former Superstars returning to the company to fill spots on the new rosters.
Of course, not every comeback is a success, however, and WWE fans only have to look to the example of Batista to see that. The four-time World Heavyweight Champion's return between 2013-15 was marred by boos and creative differences and, ultimately, ended in failure.
Speaking during an appearance on MLW Radio recently, the wrestler-turned-actor has now revealed two of the biggest regrets he has about the way his return panned out.

Alongside issues stemming from the WWE's desire to have him return as a babyface, Batista admitted to issues with his own body meant he didn't fulfil his potential during his comeback run:
"There's a few things personally I wish I could have changed about coming back," the Guardians of the Galaxy star explained.
"Like I wish I could have been in better shape. I should have been in wrestling shape and I really wasn't, for a few different reasons."
Elaborating on the reasons for failing to return as the same physical force he was during his title-winning prime, Batista cited two issues - one he could do nothing about, and one self-inflicted:
"One, I was injured coming back. I had a really back Achilles tendon injury," he said. "But also I had stayed away from the weight and really strenuous working out for years because I was trying to conform and I wanted to be an actor.
"I was trying to get away from that muscle-bound look. The fans always kind of respected me for that look...and I didn't give them that. And I really wish I had.
"Now when I look back at pictures I really am embarrassed about the shape I was in. I should have been in better shape for that (comeback)."
Batista's admission should perhaps be a warning to any of those stars the WWE is currently calling and trying to recruit for the upcoming WWE Draft. Sometimes things are best left in the past.
