Hey,

Some ideas and input from my side. There are many counters for Kakuzu currently, however, like Kakuzu meta himself, it needs some time and specific builds to get these. As stated above, a great option is to really use some super armor suppressing ninjas. Shira is a great ninja and he can counter Kakuzu, however, he needs a lot of support. What I was testing myself and was working perfectly are different combinations of him with examples such as :

a)Shira - Minato Hokage - Ningendo ( Of course you need all the skill breaks of Ningendo, especially the chakra stealing chase, including his immunity to debuffs passive)
b)Shira - Itachi Edo - Hokage Minato/Gakido/Ningendo/any other strong healing-cleansing-buffing support

You'll always need someone to buff you resistance in the team and be a really strong support for your Shira. Earth main is of course preferable. I managed to counter up till 50-60k power difference of Kakuzus with the above, more, is almost impossible. Haven't tried tho for a long time.

In general, recent skill trials and skill broken ninjas can counter him more ideas can be with Killerbee. His eight tails version is really amazing and can counter Kakuzu if you manage to give him a strong enough support. Edo Itachi and Edo Minato barrier or anything else that you think will help him be around some rounds is enough. You must be in general careful about that Kakuzu reset mystery, you'll have to be right on timing, otherwise your opponent may end up interrupting you.

Other team is our famous Yagura Edo - Kushina team, It's a team that can scale so much and be so tanky, self heals non stop and that will eventually kill Kakuzu. Like the other builds however, it also needs a lot of time and investment to get them both these breaks.

There are some more teams around, but mostly, or actually almost always, you need specific ninjas to be able to counter him. If you are slower than the opponent, you must be extremely careful. If you are faster, you can even try out some water main shark bomb teams, she won't have any issue to bring him down.


Hope that helps and good luck!
