I believe that Part one or two Sannin could beat their "Prime" counterparts. Prime is just an age, you have more experience and knowledge as you age and are arguably stronger.What's your point ?
Lol pretty much.Well For Hiruzen, onoki and lady chiyo it seems so
That makes sense. U_UPrime is subjective and subject to general relativity.
What you see as someones prime doesn't have to mean it is their prime.
That makes more sense if you look at it that way. Prime isn't an age but their strongest.I see a shinobi in their prime as the point in their life where they're strongest, regardless of age.
