The Undertaker is returning to WWE for SummerSlam and there are strong indications that he'll be at Sunday's WWE Battleground event too. The big questions are why is he coming back and what's he going to do? With WWE business being a bit stagnant, it's no surprise that they are calling on the 25 year WWE veteran to come back for a major storyline to help save the summer. The Undertaker hasn't appeared on WWE TV at all this year, so next Monday's Raw, where he's expected to appear, should create a memorable moment just to see what he might do. Could he be targeting Brock Lesnar, Seth Rollins or Sting? Nobody really knows at this point and that's what makes it fun. It was also reported this week that Sting is coming back for SummerSlam as well, which means that WWE could finally do an angle with them. Would they be opponents or allies in a fight against evil? It makes a lot of sense to bring them back at the same time and put them in the same storyline. Now that The Undertaker is back, it's time to explore some possibilities about what he might be doing in WWE for SummerSlam and beyond.
