When Hiruzen finally retired and named Minato Namikaze his successor, Orochimaru saw no more reason to remain in Konoha and began to be less discreet with his actions.[ch. 116] This led to his experimentation on the cultivation of Hashirama Senju's DNA with sixty children he kidnapped to recreate the First's Wood Release techniques, having already done so with Danzō, while also endowing the elder with multiple Sharingan.[ch. 291][ch. 478] However, as his test subjects began to die off, Orochimaru was caught red-handed by Hiruzen, who knew it was his duty to kill him yet lacked the will to do so.[ch. 121][ch. 122] Leaving Konoha and his emotionally broken mentor, with Jiraiya's pleas for him to reconsider falling on deaf ears, Orochimaru was unaware that only Yamato had survived his experiment.
Another unique trait of Kamui is that it allows the user to teleport themselves to any location they desire, including the other dimension. When using Kamui to teleport themselves, whatever the user is touching will be warped along with them and the user's chakra becomes untraceable.[ch. 395] By his own admission, Obito is capable of finding anyone and teleporting to their location regardless of where they are.[ch. 453] Despite not always being present, Obito can keep his targets under genjutsu while they are confined inside this pocket dimension and thus, keep them incapacitated for extended durations.[ch. 520]
Sunagakure frequently fought with Konohagakure; Chiyo's attempts to poison enemies during the Second Shinobi World War were often counteracted by Tsunade. To compound this fact, following the Third Shinobi War, the Wind Daimyō began outsourcing missions to Konoha, leading to a lack of funding for Sunagakure. To make up for the loss of military power this created, the Fourth Kazekage had Chiyo seal Shukaku into its third host, his own son: Gaara.[ch. 262] It was hoped that Gaara would become a weapon for the village, but the power of Shukaku was too unstable and overwhelming for Gaara and the idea was abandoned. The village then had to rely on the development of new techniques and trading of gold dust in order to keep its' standing within the Five Great Shinobi Countries.[ch. 547] As time passed, however, the Fourth came to appreciate Gaara's increasing control and returned to relying on him as a weapon.
