Megonta

Megontas (, Meganta) are enemies from the Kid Icarus: Uprising.

Origin
Megontas are enemies affiliated with the Forces of Nature introduced in Kid Icarus: Uprising. Its spherical shell is invulnerable to attacks, so the player has to attack its exposed parts to inflict damage. It can roll up and slam to attack, or it can fire explosive rounds. Striking its weak spot with a strong attack will cause it to roll onto its back, leaving it vulnerable to further attacks for a few seconds.

In Smash Run
Megontas appear as enemies. Upon seeing a player, they will attempt to roll into them, causing heavy knockback. Its underside is its weak point; sufficiently strong attacks will cause it to roll into its back, leaving it defenseless until it gets back up.
