Rudol von Stroheim

Stroheim is the commander of the Wehrmacht forces who discovered Santana in Mexico. He is appropriately militaristic and menacing, but is also responsible for not only saving the life of Robert E. O. Speedwagon, but also for trying to help Joseph Joestar defeat Santana by blowing himself (and the enemy) up. He returns later as a cyborg to assist in the fight against Cars were he is sliced to pieces by Cars. He later returns again with a squad of soldiers to aid Joseph when an army of vampires tries to attack him. Later, when Joseph takes a plane to try and send Cars into a volcano, he saves him by jumping out the cockpit, breaking his legs as a direct result. He dies in 1943 in the front during the Battle of Stalingrad as a German soldier. He is the one who made Joseph's prosthetic cyborg hand. (Source: Wikipedia)
