Aura

An Aura is an energy barrier found throughout the Mega Man Battle Network series. Certain viruses, such as Megalians and Scuttles, wield auras and auras can be used by NetNavis as a Battle Chip. Bass is also known to wield auras.

Auras are capable of deflecting all attacks up to a certain threshold, above which the Aura disappears after blocking off one hit from said attack. Some Auras have elemental alignments, where they immediately disappear after getting hit by their weakness regardless of how strong it was. Certain Wind-based attacks and Battle Chips are also capable of automatically removing Auras regardless of their strength.
