Screwdriger (スクリュードライガー) is the squid-like enemy in the water stages of Mega Man Zero. Its name is a modification of the word "screwdriver" (スクリュードライバー). It appears in the first stage of Fairy Leviathan. It floats aorund in the water and swims toward Zero when he gets too close. If enough of them are killed, one will drop a Cyber Elf.
