Kunai, known as Ryoute Kunai (リョウテクナイ) in Japan, is the Battle Chip family from NinJoy viruses in Mega Man Battle Network 2, Mega Man Network Transmission and Mega Man Battle Chip Challenge. It makes two kunai appear in the diagonal panels in front of the user, spinning in place and hitting targets three times. Stronger versions increase the distance that the kunais appear. In Mega Man Network Transmission it fires forward two spinning kunais diagonally up and down, and stronger versions fire in more directions.
