Kanzenshuu is kind of like the Zeno of the DBZ community to me. You really have to tiptoe on egg shells and mind every word, syllable, and punctuation point in order to keep yourself alive. If you do one wrong thing to the wrong person on the wrong day, you're gone.
DBZF is like the Beerus. Fairly lazy, but if you make an incredibly stupid move, you'll pay for it.
DBZeta is like the...uh...Colonel Blue.
