Sweet and short.
Make a player's displayed power level (as they appear to other players) a fraction of their real power level equal to the amount of KI they have left out of their KI maximum.
I'll try to simplify this:
Say your KI is at 50%, so half your bar is colored. When people look at you using their scouter, they'll see only half your power level (as it is shown on your screen).
Perhaps a function could be installed to drain your KI deliberately, effectively hiding your power level? (Right Ctrl, etc.)
