The Dragonreign (天覇真竜王 Tenpa Shinryūō, lit. "Heaven-reigning True Dragonlord") is a set of Lances that can be wielded by Xaldin in Kingdom Hearts 358/2 Days. It can be upgraded to the Dragonreign+.
A Dragonreign lance's shaft is white with black ends. The two colors are separated by small gold rings. The lower blade has a three-pronged, trident-like shape, with the middle prong being shaped like one of the spikes on the Nobody logo. It is gold with black interior edges. The main shaft of the upper blade is red with thick, gold edges and is much larger. It has two semi-circle shaped chunks taken out of each side, causing it to resemble the Nobody symbol. A long, gold spike shaped like those on the Nobody sigil sprouts from the middle of each side, while two more, smaller gold spikes with black inner edges jut off from the base of the blade. All four of these spikes point diagonally downward.
"Dragon" simply refers to Xaldin's heavy association with dragons. "Reign" typically refers to the rule of an absolute monarch, which refers to the Dragonreign's power. The weapon's Japanese name carries a similar meaning.
Dragonreign’s normal ground combo starts with a sideways slash using one lance, followed by a downward diagonal slash using the other lance. Xaldin then swings his lances from the same starting point upward to two far points in a "V" formation. The next attack of the combo consists of Xaldin swinging his lances above him in a circular formation, like a fan before swinging all six lances in a circle above his head, resembling helicopter blades.
The aerial combo consists of Xaldin swinging his lances above him in a circular formation, like a fan, followed by a thrust of all six lances forwards at once in a pointed, star-like shape.
