Dōjutsu: Inferno

Itachi's ultimate attack from the first two Naruto Ultimate Hero games. It is activated by Itachi's Sharingan, although in the second Heroes game it would be activated by his Mangekyo Sharingan, which would cause the opponent to be consumed by a large pillar of black flames. After the attack ends Itachi's Tsukuyomi Mode is activated.

Trivia
The attack is most likely a variation on the Amaterasu.
