yeah power levels were just ridiculous . thats why by the frieza saga they kinda went out the window , i believe the author/writer/creator did this on purpose just to show there is no real way to gauge the characters .; every arc a new villain will be more powerful than the one before and goku and friends will have to train hard to meet the challenge .
@sog7dc: MMH kinda was, with stormwatch, but the series fell to pieces . i remember when he was with the JLI and they had space adventures. a JLC(osmic) or maybe have the JLU stand Justice League Universal would be cool. their first mission had to do with space and they introduced adam strange and ultra , you don't get much cosmic than that!
