Ken Shamrock went from the world of MMA to pro wrestling and was a key character in the attitude era.
He was joined briefly by Dan Severn in the late 90s, while Quinton ‘Rampage’ Jackson tested the waters at TNA for a bit.

But there hasn’t been many more who have swapped the Octagon for a WWE ring.
But here’s five athletes we’d like to see one day make the switch.
5. Anthony Pettis
The former UFC Lightweight champ would be a worthy guest on Chris Jericho’s talk show as his octagon work has been one big highlight reel.
His off-the-cuff style and thinking on (and using) his feet would be exciting to watch inside the squared circle.
And I wouldn’t mind seeing his springboard kick off the cage that he landed on Benson Henderson in a Hell in the Cell setting.
If you haven’t seen the Showtime kick, here it is:
4. Ronda Rousey
I don’t know a single person who didn’t love Ronda Rousey’s spot with The Rock at Wrestlemania.
‘Rowdy’ is one of the baddest women on the planet and a stint in the WWE Divas division sure would shake things up.
I believe Rousey could take the belt on a run similar to Brock Lesnar’s latest championship stint with the woman, who finally beat her being instantly made a star.
It would also provide a legitimacy to the women’s ranks.
She also loves pro wrestling but we’re more likely to see Rousey on a one-off basis.
3. Chael Sonnen
Chael Sonnen has already been treating his pre and post-fight interviews like he’s been in the WWE for years.
If there’s one thing he knows how to do, it’s promote a big match.
He’s had a trial with WCW in the past and already calls himself ‘the Bad Guy’.
So if Vince McMahon ever needed a good heel…Give Chael a call.
If he doesn’t, the NCAA Division one wrestler will just claim he’s the champ until he rings anyway.
2. Conor McGregor
The most charismatic man the UFC has on their books.
He’s the guy everyone is talking about and causes a reaction from fans whether its positive or negative.
That is everything WWE creative are looking for. Just look at John Cena.
I think everyone would also love to see McGregor take his legion of noisy Irish fans to Wrestlemania. What an atmosphere that would be.
1. CM Punk
Let’s face it, what wrestling fan wouldn’t love to see this guy back inside a wrestling ring again?
He was the self-proclaimed Best in the World and was the longest reigning WWE champion of the past 25 years.
He caused controversy and danced the line between real and fake to perfection.
His infamous pipe bomb and storyline that culminated in blowing that kiss at Money in the Bank is in my personal favourite wrestling moments of all-time.
It’d be amazing to see him stand on the ramp and declare: “It’s Clobbering Time!” to the WWE Universe again.
And I feel we still haven’t had the Punk v Cena pay-off for the title at Wrestlemania which I’d have happily travelled half way across the world to see.
But with his wife AJ Lee retiring from the business and his bitterness towards the WWE, that seems more and more unlikely everyday.
