The Storm Serpent is a new Storm-attribute Box Weapon as of the Future Arc. One of the Box Weapons used by Baishana, his in specific is based on a U.M.A. called a Tsuchinoko. Due to its relation with the mysterious creature, Hayato Gokudera became excited when he first saw it during the Merone Base invasion. In response, Ryohei Sasagawa commented that a real one had been discovered three years prior.


There is a disintegration effect in the Flames of its scales and anything that touches them is pulverized. It is the first Box Weapon to possess the mechanism to power up itself by preying upon other Box Weapons. Its stats grow along with its size and ultimately all but Intelligence become A-Rank.
