Batista would be higher on the list if it weren't for the sheer improbability of him showing up at Hell in a Cell - nevertheless, this is WWE we're talking about, and big surprises come with the territory. Batista has become a mainstream star since the release of Guardians of the Galaxy, and though he's currently filming Bus 657 with Robert De Niro, a brief appearance could be possible... and newsworthy, if he teases a big match. There aren't that many opponents who can conceivably stand up to Brock Lesnar, but Batista may be one. Given the cache his name has gained over the past few months, a Brock-Batista contest would possibly be the strongest non-Rock bout the company could put together, in terms of mainstream publicity. Add to that the fact that Big Dave has real fighting experience (not like Lesnar, of course, but still), and he could make a worthy challenger to "The Beast Incarnate." A Brock-Batista match would be killer for Survivor Series or Royal Rumble, and it could all start here.
