Formica Regia

Formica Regia (フォルミカ・レギア): The Queen Ant Lord, armed with a trident named the Hellish Glaive (黄泉の鐙). She leads the pawns and soldier into the base, over-powering Gills by ripping his arm off as he collapses from shock. She battled Agito, only to be killed by him with Shining Form's Shining Rider Kick.
