One word describes Horsehead : maniac! He is one of the fleet commanders but he commands by fear. He threatens his crew with instant death if they question his orders or make a mistake. To be assigned to Horsehead's team is not good for your stress levels.
Horsehead has been in the DDS for a long time and is a great warrior. He worships the Windscorpion who he sees as one day taking the DDS back into the Hell of Total War and drowning the ocean in a sea of blood. This is his dream and he hopes it will one day happen.
He also is quite keen on Rotarios who he thinks will also bring more violence to the DDS. Horsehead is loyal only to his plasma cannon.
