What is the signature move of the Pokémon Lucario? Lucario’s signature move is Aura Sphere.

Aura Sphere is a special Fighting-type attack that fires a concentrated blast of aura. Its defining battle feature is perfect accuracy: under ordinary conditions, it does not miss. That makes it a reliable alternative to stronger but less dependable attacks such as Focus Blast.

The move is closely tied to Lucario’s concept. Lucario is portrayed as an aura-sensitive Pokémon able to perceive and manipulate the life energy surrounding living beings. The connection became especially prominent through the Pokémon animated series and the 2005 film Pokémon: Lucario and the Mystery of Mew, where Lucario’s aura abilities are central to the story.

Aura Sphere was originally strongly associated with Lucario, but it is not permanently exclusive to the species. Other Pokémon can learn or use it in various games, so “signature move” means the attack most identified with Lucario rather than a move only Lucario can possess. Focus Blast is also Fighting-type, but it has lower accuracy and is not Lucario’s signature attack.
