Wanting to be a hero like most members of his family, Jaune Arc used fake transcripts to get into Beacon Academy, as he had never went to a combat school before-hand. At Beacon Jaune became the leader of Team JNPR, and soon got actual training by Pyrrha Nikos.
Aura: Aura is the manifestation of one's soul and can be used for wide range of abilities. The specific abilities and their strengths differ from individual to individual and are dependent on a number of factors, such as experience, training and innate skill. Jaune's aura can heal minor injuries and increase the strength of his attacks.
Crocea Mors: A combination between a sword, sheath and shield. The sword is a normal sword. While the sheath transforms into the shield, which can block heavy hits.
Broadsword Form: By folding the shield over the sword's blade, Jaune can form it into a large broadsword. This form of Crocea Mors is much stronger and sharper than the normal sword, but it leaves Jaune without a shield.
