Storm Scorpions are Box Animals that clothe their tails with Flames. Bianchi used this Box Weapon during the preparations for the Merone Base invasion. She helped Gokudera with his training by releasing several of those to act as mobile turrets. At the time, she mentioned to him that his future self could destroy 20 of those in a minute.
The Storm Flames that these scorpions blast from their tails can not only instantly pulverize the enemy but also gradually weaken them like a poison. Because of that, at times it can also be used to interrogate an enemy. Also, those same Storm Flames are especially strong on its skin and can reduce nearly 90% of the damage.
