Hotarion (ホタリオン Hotarion?) is the super fast firefly Mechaniloid in Spark Mandrill's stage in Mega Man X. When entering the darkened areas of the stage, this robot will fly across, oftentimes too fast to dodge. But it lights up the path it flies through, making it both help and harm. In Mega Man Maverick Hunter X, this enemy reappears right before X fights Spark Mandrill for the last time.
