Fighting Spirit

A Fighting Spirit is when a person's ki/mana/spirit/psychic power is manifested in a physical form that acts on its own. They don't need to lift a finger to punch you; their ki will do it for them. This usually resembles Summon Magic, except that it's an extension of the user rather than a separate entity. This can sometimes manifest as an Animal Battle Aura. See also Guardian Entity.

For the other kind of Fighting Spirit, see Heroic Resolve.

Anime and Manga

 * Raoh from Hokuto no Ken, could use his Touki to attack an opponent without so much as flexing a single finger.
 * Many of the Nen abilities from Hunter X Hunter qualify, such as Razor's 13 Devils.
 * Stands from Jo Jos Bizarre Adventure. They started out as a way of making Psychic Powers more visually interesting, and they were so awesome that they eventually became the most common power in the series.
 * "Inner Sakura" is often depicted as this in some Naruto-themed videogames. Naruto's Fox Cloak can function as this, forming arms of chakra to attack independently of Naruto's movements.
 * One Piece
 * There's Haki, which can cause hundreds of people to pass out at the same time, enhance one's Attacks/Defense,.
 * Also, Zoro's Kyutoryu Asura, seeing as its described as an extension of his spirit. Although its unknown whether its related to Haki or not.
 * S-Cry-ed essentially ripped off Jo Jos Bizarre Adventure with its Alters. The only difference is that while Stands are mental constructs, Alters are physical in nature (and blow away small portions of the landscape for the material).
 * Arguably, G Gundam's Sekiha Tenkyoken, a Kamehame Hadoken that takes the form of a gigantic energy fist. Near the end of the series, Domon even uses this to perform a gigantic version of his Bakunetsu God Finger attack that grabs the opponent's entire body and not just their head.

Video Games

 * The Aura Smash technique in the Breath of Fire series creates a giant image of the user to strike the enemy.
 * Nero from Devil May Cry 4 manifests a Fighting Spirit when he uses Devil Trigger, in contrast to Dante who simply transforms into a demon.
 * Inazuma Eleven Go ups the Super Dimentional Soccer by way of Avatars, which are basically stands for football.
 * Ansem from Kingdom Hearts fights with a Living Shadow "Guardian" which floats behind him. The Guardian seems to be an ability of his, not a separate entity.
 * Persona from the Persona series are a representation of different sides of the user's personality, and are the basis of the game's magic system.

Other

 * In Magic the Gathering this is a favored tactic of the planeswalker Ajani, who has several cards involving him making avatars from his or other people's emotions. The most direct is Soul's Fire.
 * In Power Rangers Jungle Fury, a common battle tactic of members of the Order of the Claw is to summon giant ki representations of the animal one's fighting style is based on. There's one awesome scene where the Big Bad and The Hero are fighting over here while at the same time their lion and tiger spirits (respectively) are fighting over there. Exists in the sentai version but done less often. Of course, these spirit animals being giant and solid create the series' Humongous Mecha. Later, the Masters are kidnapped and forced to attack the Rangers in the form of "Spirit Rangers" that are controlled from back it the villains' base, mimicking the mind-controlled Masters' moves. After the Masters are freed, the spirit Rangers aren't always the Masters: as the Rangers' can borrow the Masters' spirit forms for Zords, they can do it to bring back the Spirit Rangers as well (and the producers get out of paying for a full physical appearance of the Masters, as only their voices are heard.) In the final episode, the Masters fight alongside their own Ranger forms.
