Iva (Often mistaken as Eva) is the final boss in Detana!! TwinBee. He using his genius to attack Melora and attempt to take over the Planet Mel. He protects his intellect with a giant, insectoid shell which, unfortunately, is so weak that it takes only a couple of shots to disintegrate. Giant brains don't survive well without external support, making Iva the most anti-climactic final boss to ever grace a Twinbee game.
