Here's one of the Darkness' favourite powers. Having obtained an Eternal Mangekyo, he has access to all of its powers. His favourite being the Susano'o. Like him, it comes off as all black with a blueish-purple aura around him, and in the first stage, he can make generate arms from the ribcage around him to attack and defend on his behalf. He can also adjust the size and length of the arms to a certain extent.
