During another, Gyūki had one of its four horns lost to A, the offending horn having killed Furui.

During one of its rampages, the Third fought Gyūki one-on-one until they both collapsed from exhaustion. Despite these setbacks, the Third Raikage believed a jinchūriki for Gyūki was too valuable of a war deterrent and decided to keep looking for a compatible one, to which he would form a special coalition to subdue and seal it in the Kohaku no Jōhei. Throughout the years, none of Gyūki's former jinchūriki - such as Blue B, and his uncle and father before him - could control its power and the ox would constantly go on a rampage, destroying the village and killing many of its inhabitants. Gyūki and the Third Raikage collapse from exhaustion. At some point in the past, one Kumo-nin attempted to mimic the Gold and Silver Brothers by eating one of Gyūki's chakra meat tentacles in the hopes of gaining jinchūriki-like power, but died in the process.

He also foretold of a day when they would be brought together again - though not as they were - and that at that time someone would emerge to show them what true power is. Some time after being created, the Sage explained to the young tailed beasts that a link existed between them despite their separation.
