Mahvas (マーヴァ, Mahva) are enemies from Kid Icarus: Uprising.
Mahvas are enemies introduced in Kid Icarus: Uprising and are affiliated with the Forces of Nature. It functions similarly to a Shildeen from the Underworld Army: it projects a shield to protect its allies. Unlike the shields produced by Shildeens, however, a Mahva's shield has a shorter range of effect.
In Smash Run
Mahvas appear as enemies. They surround themselves with a large barrier, which also protects other enemies inside its area. The barrier is impassable and pushes players on touch. However it can be attacked: after repeated hits it will turn yellow, then red and in the end it will shatter, leaving the Mahva vulnerable and making it attempt to run away. If left alone for long enough, it will regenreate the barrier at full strength again.
A strange, fishlike thing that shrouds itself in a large, spherical barrier. When it sees one of its allies, it extends the barrier to protect them as well. As you attack the barrier, it'll slowly change color until it finally breaks. That's when the Mahva will try to escape. Finish it off before it does to nab yourself some defense stat boosts!
