Speaker Banki (スピーカーバンキ Supīkā Banki): A speaker (スピーカー supīkā?) Savage Sky Barbaric Machine Beast sent by Kitaneidas, able to convert beautiful sound waves into noise pollution with his microphone spear before shooting out the resulting sound waves from his speakers. Speaker Banki is later upgraded to generate louder sound waves that can block most attacks. However, Speaker Banki's one weakness was the (nonfunctional) speakers on his feet. He is the first to be scrapped by Engine-Oh Gunpherd, as it could break through the barrier.
