Play Road to Wrestlemania with Christian. Talk to Edge at Elimination Chamber PPV about the Time Machine. Head to the GM Office and talk to Mr. McMahon. It turns out the time machine is broken into three pieces. Look for the Edge and Christian action figures. They are between the bookshelf and the TV. After leaving you'll get a phone call from Edge. The "flux capacitor" is in the Green Room (a Back to the Future reference. The "phone booth" in the parking lot (a Bill & Ted reference). Go to Edge with the three parts and you'll get the Time Machine. This allows you to travel to any point in "time" on the Road to Wrestlemania. It works with any superstar.
