From the start of the series, we saw the Tailed Beasts as large, vicious, and angry entities bound inside the bodies of jinchuriki. They were shown to despise the humans who bound them and used their power for personal gain. But they weren't always like this.
Initially, they were shown as small and emotionally open towards the Sage of Six Paths. While I understand why they hate humans now, I don't understand why and how they grew larger from their small size to something equivalent to an 'adult size'?
They are now shown as a large mass of chakra. When they die they re-form. Also, as we have seen, when the kyuubi was divided into two separate parts, his size was reduced. But that reduction in chakra didn't make him small again.
So can anyone explain:
- How did the Tailed Beasts grow from chibi to adult size? (Do they grow up like normal animals?)
- Also, do chibi Tailed Beasts have less power and chakra than their adult forms?
