Survivor Series is just four days away, but the brand invasions have continued to occur.

It all started with the NXT takeover of SmackDown on November 1, which was an emergency situation due to most of the roster being stuck in Saudi Arabia after Crown Jewel.

WWE made the best out of a bad situation, and they followed it up with a series of infiltrations, which have mainly seen NXT come out on top in a lot of them.

Adam Cole and Shayna Baszler have been prominent on both Raw and SmackDown, and on Raw this past Monday we saw the first teaser to a potential MMA Horsewomen against WWE Horsewomen match.

Also on Raw we saw a full-scale brawl to close the show, which was instigated by SmackDown superstars interrupting the Viking Raiders' match against Ricochet and Randy Orton.

And then that triggered the next wave of superstars - this time from NXT - and suddenly Triple H's face popped up on our television screens.

Not content with trying to convince Kevin Owens to return to Wednesday nights earlier in the night, The Game stated that NXT's doors would be 'wide open' this week as they issued an open invitation to any superstar from any brand.

We've only seen The O.C. and Bayley come to Full Sail in recent weeks, but from Triple H's words earlier today, we could be seeing some of WWE's biggest stars in Orlando later on.

NXT's creator told journalists -per talkSPORT's Alex McCarthy - in a pre-WarGames conference call that a lot of main roster superstars that fans wouldn't expect to show up were 'on their way' to Florida for the show.

This could mean the likes of Owens, Becky Lynch, Charlotte Flair and Seth Rollins are all returning to Full Sail for one night only, or The Fiend could even show up and destroy some NXT stars.

With HHH also revealing that the fourth member of Team Ciampa for WarGames will be revealed on Saturday night and is a 'huge surprise', NXT could have two of the best shows during Survivor Series week - and it may even beat AEW Dynamite in the ratings tonight.
