Adolf Hitler (Wolfenstein 3D)

"Die, Allied schweinhund! (Die, Allied pigdog!)."

- Adolf Hitler (Wolfenstein 3D)

Adolf Hitler (also known as Mecha-Hitler or Armored Hitler) is the leader of Nazi regime, boss of Episode 3, and the final boss of the original Wolfenstein 3D before the release of the Nocturnal Missions expansion pack. When the player first meets Hitler, he'll be in a large mechanical suit that's armed with quad Chain Guns. After having around  damaging half, the suit will blow up, and Hitler will jump out with dual Chain Guns.

Hitler fires 5 bullets per volley in the two forms. After being defeated, he will talk before melting into a pile of blood and bone, triggering the ending of the original Wolfenstein 3D.
