Rudol von Stroheim

Major Rudolph von Stroheim is a character from Part II: Battle Tendency. Stroheim is, at first, an antagonist, but later proves to be an effective ally.

Story
When we are first introduced to Stroheim, he is a callous, cruel, demanding Nazi officer who has the foolish idea to experimenting with the Stone Mask in order to further the increase the power of the Nazi army.

He takes an injured Speedwagon to the Nazi base in Mexico and asks him about the Pillar Men. It at this moment that we see that Stroheim has captured one of them, which he dubs "Santana."

Stroheim eventually sacrifices himself in an attempt to stop Santana's rampage.

Resurrection
Thanks to Nazi science, Stroheim was revived with cybernetic parts (including a machine gun on his chest and a strange sort of monocle that presumably serves as a Terminator/Robocop-esque radar system) and had attempted to fight Cars near the end of Battle Tendency.

After the battle with Cars, Stroheim never meets Joseph again and is said to have died on the Russian front during WWII.

Trivia

 * It is likely that Guile from the Street Fighter series is based on Stroheim. Specifically, their hair and physiques are quite alike, although Guile is an all-American soldier and Stroheim is a jingoistic Nazi officer. M. Bison from the same series may also have been based on him.
 * His one of the many character to receive a Steel Ball Run counterpart, this one already been a cyborg from the beginning.
