Iva (often mistaken as Eve or Eva) is the final boss in Detana!! TwinBee.


Using his genius, Iva kidnapped Princess Melora as part of his plans of taking over planet Mel. He protects himself 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.
