Since white zestu can copy person chakra and transform in to that person

[EdoDarkLighting]

Can he copy a tail best chakra?????

 

[SanjiNL]

Only their chakra signature, to make it seem like they're the person who's signature they copied. They don't actually have their chakra.

 

[-ahhimane-]

No, he cannot copy chakra levels. And of Bijuu? Not at all.

 

[fayeon]

Its not the same chakra its just copying their chakra signature which make sensor useless .

 

[UchihaNagashi]

What would he do with someone else's chãkra...? :|

 

[Ovan]

Answer to your question. He can't trick an Uchiha or a Tailed beast with it.
