Mahva

The Mahva (マーヴァ Māva) is a Forces of Nature enemy that debuted in Kid Icarus: Uprising.

Physical Appearance
The Mahva is a white creature with six yellow eyes, vaguely resembling a jellyfish. It possesses cloth-like blue and purple tendrils which hang down from its underside.

Kid Icarus: Uprising
The Mahva's main strategy is to summon a green shield around itself and allies alike, which changes color when damaged. Once broken, the Mahva will be left vulnerable for several seconds until it erects its shield again. Additionally, it possesses a basic projectile attack, though this is exclusive to Land Battle.

Super Smash Bros. for 3DS/Wii U
Mahvas appear as enemies in the multiplayer feature Smash Run. Defeating them grants the player power-ups.

Mahva
''Mahva defends itself with a sphere of water that only allows friendly fire to pass through. This makes it an ideal front-line soldier for the Forces of Nature. But don't give up: persistent attacks will eventually break through Mahva's shield.''

Mahva
''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!''
