There's absolutely no doubt that John Cena is one of the biggest WWE stars of all time.He's so big, in fact, that his career appears to have moved on from pro-wrestling. 

SPORADIC APPEARANCES

The 16-time World Champion hasn't been seen in the ring since WrestleMania 34, where he took on The Undertaker on the biggest of stages. 

Following that, Cena has been on hiatus, mostly to concentrate on his acting and television career - and really, he can't be blamed for doing that. 

He did make one rare WWE appearance earlier this month, at a show in Shanghai, where he debuted his 'sixth move of doom' - a variation of the lightning fist. 

Clearly, even while he's away from the company, The Leader of the Cenation is still working on his move set - and in October, he'll be stepping into the ring once again.

A BIG RETURN

At WWE's Super Show-Down event in Australia, Cena will make his comeback in a tag team match. 

He'll partner Bobby Lashley to take on Kevin Owens and Elias on October 6, but following that appearance, it's not clear what his future holds. 

In fact, the WWE turned Hollywood star has caused a stir on Twitter this week, by posting a very cryptic tweet. 

CENA'S WORDS OF WISDOM 

"Nothing lasts forever. When doing something you love make sure to be present and enjoy it. That way if and when it ends, you can look back with fond memories instead of regret," he wrote. 

Now, we have absolutely no idea what this means - he could be hinting at a number of things.

Is he suggesting that he'd rather be present and enjoy his remaining time in WWE? Or maybe he's saying that about his acting career.

Cena could also be talking about his past relationship with Nikki Bella, or he could be speaking in a general context. To be honest, WWE fans on Twitter don't know what to make of it. 

Right now, we just don't know what he's talking about, although some think he could be hinting at retirement. It will be interesting to see if he expands on these thoughts over the next few days.
