In the World Tournament Stage, your character floats over the ground around the arena instead of physically touching it. Why is this? Because in the source material, touching the ground means you lose the match.
The player character can't wish for immortality, which makes some sense as in DBZ it's something of a character alignment thing to actually desire immortality, but it seems odd you can't use the dragon to wish for something similar to help you patrol. Thinking about, though, it would make sense if the characters already had a form of immortality because even though they can get knocked out it's impossible for them to die. It's quite possible the Time patrolers, or at least those deemed important, get a wish of immunity to fatal blows so the Time Patrol never needs to worry about losing members on mission.
