Satori in Naruto

According to Gamabunta, Satori is the point at which the Box of Ultimate Bliss "brings forth," "actuates," and "ends." Beyond that, Satori's past is largely a mystery, just like the Box. The only things known about Satori are that it has been alive since the Sage of the Six Paths and that it is only the Box's puppet. Satori will toss victims into the box after becoming the host of one who exits the box and returns, gaining the demon's abilities while also having their mind corrupted.

Mui asked the box to let his kid Muku out, and when it did, the boy came out and killed his father. After Mui was defeated, Ryuzetsu, a childhood friend of Muku's, revealed herself, and Muku grew troubled and changed into Satori. He attacked the prison after changing into the beast, putting prisoners and the four council members of Hozuki Castle in the box, which brought him into battle with Naruto and his allies.

Finally, Satori used his claw to impale Naruto and Ryuzetsu through their abdomens, which they used to stop Satori from dodging attacks and pinned him down. Mui was then able to restrain Satori with the Fire Release further: Great Fire Heavenly Prison which left him defenseless to Naruto's Wind Release: Rasenshuriken. After claiming to return to normal, Satori once more took control of Muku, killing Mui.

Muku then killed himself and returned Satori to the box by using the Fire Release: Demon Lantern to break the seal of the Heavenly Prison on his own body. The box containing Satori was then thrown into the whirlpools in front of Hozuki Castle, never to be recovered.

Satori is a bloodthirsty creature who just wants to kill anyone that appears in front of him.

The Eight-Tails and Gamabunta are similar in size to the beast, which has huge wings. It is covered in black feathers, is headless, and has bones protruding from its mouth on its breast. It also possesses a long, skinny tail, clawed hands, and feet that have skin so thin that it almost looks like bones.

Satori had the ability to shoot its feathers like needles which can pierce through any human and can kill them. It also can shoot a Giant Red sphere, which looks like Tailed Beast Bomb. The creature is also very fast and can detect the fear emotion of anyone.

• Based on the yokai of Japanese folklore, satori is a phrase for enlightenment used by Japanese Buddhists and means "understanding."

• Satori is very similar to the "Nightgaunts" from H.P. Lovecraft.
