Sage Monkey Fruit

The Sage Monkey Fruit (仙猿の実, Seizaru no Mi) is a fruit born from plants grown by Konohagakure that were saturated by the chakra of Son Gokū. By devouring the fruit, the materials and chakra infused into the fruit saturate the body and impart said chakra into them, allowing them to also gain a fragment of Son Gokū's abilities, turning them into pseudo-jinchūriki. This is a concept that was developed after studies were done on Ginkaku and Kinkaku, who had gained the powers of Kurama after consuming his flesh from the inside.

It was a process conceptualized by Kasuga Sarutobi, the Seventh Hokage, after forging an alliance with the aforementioned bijū in order to empower her village's military by artificially creating pseudo-jinchūriki. While it has only been used with Son Gokū, the theory behind these chakra fruits can be applied for other beasts as well. Kasuga's intentions are to create nine different types of fruits after acquiring all nine of the beasts.
