Kakuzu vs Deidara and Sasori

[USSJ Future Trunks]

Yes he breathes but he has raiton to neutralise C4.

raiton only neutralises it if cast on oneself. kakuzu has no idea hes breathed anything let alone figured out its achilles heel is against users of raiton armour or chidori nagashi

He is far more smarter

sasori was the genius of his village and was the only one who could make human puppets. deidara quickly outsmarted gaara and kakashi
