Cursed Seal of Heaven

The Cursed Seal of Heaven is one of the strongest cursed seals, the other being its counterpart, the Cursed Seal of Earth. The seal consists of three tomoe (the design known as mitsudomoe), similar to the Sharingan, which, when activated, spread flame-like markings across the user's body. Like all cursed seals, the user receives increased chakra levels and physical capabilities when the seal is active.

When one activates the second level of this Cursed Seal, their skin turns dark-grey and hair grows and turns dark blue. The sclerae of their eyes turn black, while their irides turn yellow. Additionally, users can grow webbed-claw-shaped wings from their back which could use to fly and glide, and a dark, star-shaped mark appeared across the bridge of their nose. Skilled users are able to replace a lost limb, just as Sasuke had done during his battle with Deidara.
