Spikey

Spikey, known as Garū (ガルー) in Japan, is a virus from the Mega Man Battle Network series. They are large canine-like viruses that spit fire. In Mega Man Network Transmission, their attack patterns are very similar to the Friender enemies in Mega Man 2. They also teleport around the field very fast unless they stop to attack. The variants are faster and the attacks explode in different directions depending on their level.
