In the town of Quelb, Kelger challenges Bartz Klauser to a fight, believing him to work for Exdeath. Kelger initiates his "Lupine Attack" (known as Pine Attack in the Anthology translation), which takes advantage of Kelger's incredible speed; he circles around Bartz so fast as to leave after-images in a ring around his target, with Kelger himself landing surprise attacks at regular intervals. Bartz is able to focus enough to find Kelger's actual position, and strike him with a powerful blow that sends him through a door.
Lupine Barrage is a Soul Break available to Bartz, released before Kelger was made a playable character. It deals 5 non-elemental physical attacks to 1 enemy, and raises the user's Attack a moderate amount. The attack has Bartz circle his target rapidly, leaving multiple after-images, before striking.
Lupine Attack is an Ultra Soul Break available to Kelger. It deals 10 physical Earth and Wind attacks to a target, temporarily boosts the damage of the user's Ninja abilities, grants Mirror Image to the user, and causes the user's Earth abilities to trigger the additional attack Lupine Chase. Lupine Chase deals 4, 6, or 8 physical Earth, Wind, and non-elemental attacks to a single target, depending on how many stacks of Mirror Image the user has.
Kelger also has access to an Awakening, named True Lupine Attack. True Lupine Attack deals 15 physical Earth and non-elemental attacks to a target, infuses the user with Earth, increases their damage cap by 1 level, and grants Awoken Ninja Mode, which grants infinite uses to Ninja abilities and causes them to dual-cast. The attack also causes every second Ninja ability to trigger Lupine Pulse; an additional attack that deals 4, 6, or 8 Earth and non-elemental attacks to a target, based on how many stacks of Mirror Image the user has. Lupine Attack, True Lupine Attack, and Kelger's Arcane Overstrike, Lupine Boost, all feature Kelger circling his target, leaving after-images from the extreme speed.
Lupine comes from Latin lupīnus, from lupus ("wolf"). It means of, or pertaining to, the wolf, or wolflike.
