The Zantetsuken in Final Fantasy XIII is an incarnation of the recurring weapon that appears in several games in the Final Fantasy series. While the Zantetsuken is traditionally Odin's signature weapon, its Final Fantasy XIII incarnation is more closely associated with Lightning. The weapon is called Gagnrad (ガグンラーズ, Gagunrāzu?) in Lightning Returns: Final Fantasy XIII.
The Zantetsuken is a pair of large curved swords that each form a hook shape. The swords are identical in design with no known differences between them. The hilt is formed from a golden horse's head and front hooves with the blue handle and lower section of the handguard coming from the head and hooves and joining at a golden pommel, which is where the blades connect. From the bottom of the horse head's neck extends a white plumage of feather-like spikes along a central green core decorated with lightning-like jagged yellow lines. The inside of the blades' hook shape bears writing in Etro script, which reads "Odin." The Lightning Returns model features a different handle, with the pommels being larger and the blue handles and handguards being smaller and differently shaped.
The Zantetsuken can be wielded as either two individual swords or a single double-bladed sword. The swords face opposite directions when connected, forming an "S" shape.
The Zantetsuken is wielded by Odin in battle, both as a boss and as an ally. When Odin transforms in Gestalt Mode, Lightning rides atop him wielding the Zantetsuken in its individual forms, but combines them for some attacks, and performs the finishing move Zantetsuken the weapons are named after with them. When the party crashes the Eden grand prix Lightning rides Odin in Gestalt Mode and thus wields the Zantetsuken outside of battle for the cut scene.
Lightning wields the Zantetsuken in the prologue sequence while riding Odin. Twilight Odin wields his own version of the swords, predominately colored green.
Lightning obtains this weapon from Odin himself as a symbol of his continuing support upon completion of the sidequest "To Live in Chaos" in the Wildlands. The weapon's name is not Zantetsuken, but Gagnrad, which is another name for Odin. It increases Strength by 500, Magic by 500, ATB Speed by 25, decreases maximum HP by 5% and Stagger Power by 90%. It also has two passive abilities, Strength -50%. It is classified as a dual-blade, and attacks twice per turn when attacking. The Angel of Valhalla has a tattoo in the shape of Zantetsuken above his left eye.
Zantetsuken appears as Odin's weapon during the event Lightning Strikes.
Lightning uses the Zantetsuken to execute her HP attacks, automatically swapping the Blazefire Saber for the swords when an HP attack is performed. She wields the Zantetsuken in both combined and separated states, depending on the attack. The Zantetsuken is used in her EX Burst.
Lightning's level 100 exclusive weapon is also named Zantetsuken. It provides +68 attack, +10% defense, and a Riposte effect, and can be traded for in the shop for an Omega Weapon, Survival Knife, Flash's Hope x5, and 182,800 gil. As a likely reference to Zantetsuken existing as two swords, Lightning has a second Level 100 exclusive weapon named the Odin Blade (グングニルブレード, Gunguniru Burēdo?, lit. Gungnir Blade). The Odin Blade also has 68 attack, but instead provides the abilities Back to the Wall and Free Air Dash Boost. The trade materials and cost are the same, with the exception of needing the Barrage Blade to trade instead of the Omega Weapon.
