Notes:
Dragon Ball GT: There never were any power levels given in DBGT, nor was an official list ever created. Therefore there is absolutly no fact upon which to base DBGT power levels. Besides that, DBGT wasn't created or written by Akira Toriyama, so any nuances which he put into Dragon Ball, such as power levels, would have no precedent in DBGT!
