7. Jake 'The Snake' Roberts
Despite recently undergoing surgery for muscular cancer, Jake The Snake Roberts insists he is healthy enough to take wrestling bookings. If it is the case that he's indeed fit enough, then he would be a great name to have come out during the Mania battle royal. As we saw on January's Old School Raw, Roberts appears to have exorcised his demons. The fact he will be inducted into the WWE Hall of Fame the night before Mania means he will be there and available in New Orleans for an appearance on the big event itself. Just imagine the reaction he will get if he comes into the Battle Royal with his pet snake Damien and lays it upon a knocked out heel such as Alberto Del Rio who then jumps for his life over the top rope out of there. Roberts could even enter with his close friend and rehab mentor Diamond Dallas Page. It would be fun to see the ever colourful DDP again and there's plenty of room for legends given the 30 man entry list.
