554話「兄弟共闘（タッグ）」

Itachi and Sasuke stand as a united front, confronting Kabuto. The two activate their Susanoo respectively and attack Kabuto. Kabuto reveals that he had developed a similar ability to the Hōzuki clan's Hydrification Technique as well as replicated Karin's healing abilities and Jūgo's ability to absorb natural energy. To Itachi's shock, Kabuto noted that he had discovered the Ryūchi Cave and trained under the White Snake Sage, where his master had failed. Sasuke says that Kabuto is nothing different from Orochimaru, a "disgusting" snake. An amused Kabuto stopped him and stated that he had evolved into a dragon as the latter entered Sage Mode. Back at the battlefield, Madara's clones begin to activate their Susanoo, to the five Kage's horror. While the other Kage say that it's five-on-one, Ōnoki suggests that they fight together, making it twenty five against five. Elsewhere, Kabuto casts a technique that disallowed the two brothers from seeing or hearing.
