2) Mankind
So before the haters and trolls try to eat me, hear me out: When is the last time you saw Mankind? Not Mick Foley, not Cactus Jack, not Dude Love? It's been a while. I want Mankind in a match on RAW 1000. I want Mick Foley to go into character, fully. Embrace the psychotic nature of the creature he created, for 1 night. A match against (#3) Shane McMahon would fit the bill. They could give us an old fashioned hardcore brawl. Also, Mankind might possess the most shocking Raw moment of all time (between him and 1-2-3 Kid, it's close, you decide). The night he won the title on Raw, was so great, and so unexpected that it really was a huge part in turning the Monday night wars in WWE's favour. Tony Schiavone's comments on Nitro were cruel and reeked of desperation on WCW's part. Announcing the results of RAW before they happened, he told the audience not to bother to change the channel because they were giving the title to Mick Foley. Mankind had countless moments on RAW, and he's truly a legend. Recently HHH said Mick Foley was no longer a draw and 'he should be paying us to make appearances' (if reports are to be believed). If that is true, HHH should be ashamed.
Chance of Appearance: 100% (as Mick Foley), 50% (as Mankind)
