YMMV / P-51 Dragon Fighter

• Anti-Climax Boss: Asazuka is built up as potentially capable of destroying mankind by himself...but only appears for a few minutes then is easily killed.
• Complete Monster: Dr. Heinrich Grudun is the Nazi occultist in charge of a secret project to breed dragons as aerial support for the Afrika Korps, recruiting telepathic witches to control the flying beasts and fight for Nazism. Training the dragons as living weapons to be used against Allied soldiers, Grudun unleashes them in North Africa to burn and destroy their enemies, developing more eggs to create an unstoppable army of dragons to conquer not only the region, but also the entire continent. Familiar with the existence of an uncontrollable and apocalyptic dragon, Asuzaka the Destroyer, Grudun promises to prevent his return, but releases Asuzaka anyway when he realizes that he was losing a battle.
