Batty, known as Pulse Bat (パルスバット,Parusu Batto) in Japan, is a bat virus in Mega Man Battle Network 5. It flies up to avoid attacks. When it is lowered, it will sometimes shoot out pulsar attacks. If the pulsar hits an object, sound waves bounce off that object and hit all surrounding panels, damaging anyone within those panels. Variants of the virus can either paralyze or confuse the target if the attack lands.
