In the 1960s, two astronauts, Fuji and Glenn, are sent to investigate the surface of the mysterious "Planet X". There they encounter advanced and seemingly benevolent human-like beings called the Xiliens and their leader The Controller. The aliens usher the astronauts into their underground base, and moments later the surface is attacked by a creature the Xiliens call "Monster Zero", but which the astronauts recognize as King Ghidorah, a planet-destroying monster that had attacked Earth once before. The monster eventually leaves, but the Controller states that Ghidorah has been attacking repeatedly, forcing them to live underground in constant fear. He requests to borrow the Earth monsters Godzilla and Rodan to act as sentries against Ghidorah's attacks, in return for the cure for cancer (the English dub says the formula can cure any disease). The astronauts return to Earth and deliver the message.

Harpooner Ishmael (Corey Sevier) joins Ahab (Danny Glover) and his crew on the Pequod, in this instance an armored land boat that hunts for dragons. The seven-strong crew ostensibly seeks the precious "vitriol", a highly explosive liquid substance found inside the fire-breathing winged creatures, which powers the mythical realm they live in. Ishmael joins their quest, and soon learns that in fact, Ahab's mission is one of revenge on a particular great white dragon that decades ago scarred and injured him, and also killed his sister. Forced to hide from the sunlight due to the burn wounds on his body, Ahab now tries to kill all dragons, and especially the white one. Conflict arises through a romantic entanglement between Ishmael and Ahab's adopted daughter, Rachel (Sofia Pernas), which causes hostility from the jealous hothead Flask (Larry Bagby). In the white dragon's lair, Ahab's secrets are revealed and Rachel must choose between following him on his dark quest or escaping to a new life with Ishmael. She chooses the latter and in a final confrontation, Ahab's spear, which was tied to his foot, becomes entangled in the White Dragon's neck. The creature flies off with a screaming Ahab, until he is slammed against a rock pillar and silenced. The white dragon flies off into the distance, with Ahab's body clinging on to it.

The title character Siegfried, son of King Siegmund of Xanten, masters the art of forging a sword at the shop of Mime. Mime sends Siegfried home, but while preparing to leave, Siegfried hears the tales of the kingdom of Burgundy, the kings who rule there, as well as of Kriemhild, the princess of Burgundy. Siegfried announces he wants to win her hand in marriage, much to the amusement of the smiths. By way of physical violence, Siegfried demands to be told the way. Mime, who is envious of Siegfried's skill as a swordsmith, claims there is a shortcut through the Wood of Woden; in reality, this route will lead Siegfried away from Burgundy and expose him to attack from the magical creatures inhabiting the wood. During his journey, Siegfried discovers a dragon, and deviates from his path to slay it. He touches its hot, yellow blood and understands the language of the birds, one of which tells him to bathe in the dragon's blood in order to become invincible to attack — except for one spot on his shoulder blade, which is missed after being covered by a falling lime (linden) leaf.
