Bufalo Fulmine ver. Vongola, nicknamed Gyuudon, is a Lightning-attribute animal-type Box Weapon. It is the exclusive Vongola Box Weapon for Lambo and can transform into a horned helmet and sheid. The shield was modeled after the first generation's Lightning Guardian, Lampow's, weapon of choice.
Its appearance is that of a big, black bull covered in armor that has the Vongola crest on it.
The Bufalo Fulmine ver. Vongola was created by remodeling a Bufalo Fulmine with the Vongola's latest technology.
It was first shown when an angered Lambo used it to get back at Hayato Gokudera for his insults.
By further wrapping its body that was solidified with Lightning Flames, it can withstand any kind of physical attack. The offensive power of its horns is tremendous, and that power is demonstrated when it becomes a shield through Cambio Forma.

This weapon is equipped with a horned shield and has the Roman Numeral "I" on the front to symbolize the connection to the first generation. The shield is also equipped with two horns similar to Lambo's Horns that are encircled by rings, and also forms a helmet with a Lightning Crest in the middle.
