Megonta

Megonta is an enemy that appears in Kid Icarus: Uprising, resembling a giant pill bug with a purple metallic shell that almost completely protects it from harm.

In Super Smash Bros. for Nintendo 3DS, Megontas appear as enemies in Smash Run. Like in Kid Icarus: Uprising, it does not take damage if it is being protected by its shell and can only be damaged by hitting its exposed body parts. To attack, it rolls around and slams into the player.
