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. They appear in Super Smash Bros. for Nintendo 3DS as Smash Run enemies. Like in the original game, it won't 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.
