Amaterasu produced inextinguishable Black Flame. To use it, the caster focused his gaze on a target, and pure black fire sprang up wherever his eyes landed.
The Black Flame would not go out on its own. It kept burning until it consumed its target, and its heat, like the blazing sun, could incinerate solid matter.
It was powerful enough. Its record of actually killing enemies was just a little underwhelming.
In the Original Work, it had only taken out a few White Zetsu foot soldiers.
Underwhelming or not, Amaterasu was not something an ordinary person could withstand.
But someone who immediately severed whatever Amaterasu was burning could escape its attack.
The Fourth Raikage had cut off his own arm, for example, while Madara had shed his armor.
Obito could use Kamui's Phasing to evade Amaterasu.
On its own, Amaterasu was a straightforward attack and fairly easy to dodge.
Paired with Kagutsuchi, though, its power rose several levels.
Kagutsuchi was a Dojutsu that controlled Amaterasu. Once activated, it let the user freely manipulate, shape, and extinguish the flames.
In later battles, Sasuke used Kagutsuchi to turn Amaterasu into long blades, spikes, projectiles, arrowheads, nets of fire, shields, and all sorts of other weapons.
Amaterasu paired with Kagutsuchi deserved to be called the strongest physical attack.
Even Kaguya Ōtsutsuki had to steer clear of it.
Obito quietly committed Sasuke's Dojutsu to memory.
Did this foolish kid trust someone from his clan that easily?
Didn't he know a Ninja couldn't casually reveal his abilities, not even to his closest family?
Battles between Ninja came down to how their different abilities countered one another.
Obito glanced at Liao Wu. What he wanted to know even more was Liao Wu's Mangekyo ability.
What Dojutsu did this ancient Uchiha possess?
Right.
Obito was not about to
