Megalian

Megalian (メガリア), or Heady as it is known as in Mega Man Battle Network 6, is a virus from the Mega Man Battle Network series. It has an Aura around it that blocks attacks below a certain damage amount. Also, these auras have elemental properties, which thus have weaknesses to appropriate elements. The player must first destroy the aura, before damaging a stationary or moving Megalian, with an attack damage higher than the specified number on the aura. When this virus attacks, it shoots its head out of its aura towards its target, making them vulnerable to attacks. Stronger variants have stronger auras (of different elements) and their attacks extend over more panels.
