when was haki first mentioned

I'm not sure exactly when it was first mentioned. It's a topic that might require in-depth research in specific historical or anthropological records.

In some fanfictions, Naruto might discover haki during a particularly intense battle. Maybe when facing an enemy with an unusual power that his regular jutsu can't handle, he unknowingly taps into his latent haki ability.

The first mention of the Infinity Stones in comics occurred in a specific comic issue in the 1970s. They've since become a significant part of the Marvel comic universe, with their powers and significance evolving over time.

Well, in the Harry Potter series, specifically in the very first book which is 'Harry Potter and the Philosopher's Stone', Nicolas Flamel makes his first appearance. He is quite an important figure as his Philosopher's Stone is what Voldemort is after. The stone has the power to create the Elixir of Life, which is why it becomes a central part of the plot in this first novel. Harry and his friends end up getting involved in protecting the stone from Voldemort.

Percy often uses Observation Haki to anticipate the attacks of his enemies. He can sense their movements and intentions, which gives him an edge in combat, especially against fast - moving or sneaky foes like some of the monsters in the Percy Jackson world.

Maybe an ancient sage in Naruto's own world who has long - been in seclusion. This sage has knowledge of different power systems beyond just chakra. He notices Naruto's pure heart and strong will and decides to pass on his knowledge of haki to Naruto, believing that Naruto can use it for the greater good of the ninja world.

In 'naruto haki fanfic', Haki can change the Naruto universe by adding a new layer of power. For example, it can make battles more complex as characters now have to consider both chakra and Haki. It might also change the way characters interact with each other, as those with Haki could sense things differently.

In fanfic, 'coating his forehead in haki' might be a way to show the character is preparing for combat or enhancing their defense. Haki in some fictional universes is a form of spiritual energy. By coating the forehead, which is a vulnerable area, the character could be trying to protect themselves from attacks, especially those aimed at the head or face.
