Description
Gastel, also known as Ghastel, is a demon who appears as a supporting antagonist in the 1987 film Dragon Ball: Sleeping Princess in Devil's Castle. He serves as the powerful leader of Lucifer's ogre demon army and is among the most formidable soldiers under the main villain's command. in terms of background, Gastel is a resident and guardian of the Devil's Castle, the dark fortress where the film takes place. His physical appearance is distinctly monstrous: he is a large, red-skinned demon covered in rough, bumpy textures across his body. He has two large pink horns protruding from the sides of his skull, bright yellow eyes, and a wide mouth. For attire, Gastel wears brown and gold protective armor over his chest, golden wristbands, and a black loincloth. One of his most distinctive features is a long, white bandage or sash that floats and wraps around his body, which he can weaponize. He primarily wields two large clubs with spherical ends, though he also has been seen using a trident in combat.

Regarding personality, Gastel exemplifies the traits of a loyal and tenacious soldier. He is aggressive and confrontational, immediately attacking the protagonists Son Goku and Krillin when they intrude upon the castle. His most notable characteristic is his persistence; he does not give up easily and is capable of quickly adapting to the flow of battle. Even when initially knocked back by Goku's Power Pole, Gastel relentlessly resumes his assault. This unwavering dedication to his duty as a guardian, however, ultimately proves to be his fatal flaw, as his refusal to retreat leads directly to his demise.

Gastels role in the story is to act as a significant physical obstacle for Goku and Krillin early in their mission to retrieve the Sleeping Princess. Shortly after the two boys infiltrate the Devil's Castle, Gastel confronts them. He engages Goku in a fierce close-quarters battle, creating an opportunity for Lucifer's lesser demons to swarm the area. Gastel demonstrates his resourcefulness during this fight; when Goku attempts to escape by calling upon the Flying Nimbus cloud, Gastel reveals his own ability to fly, which allows him to give chase directly through the air. Throughout the pursuit, he continues to attack using his bandages and projectiles, managing to keep pace with the heroes for a considerable time.

In terms of key relationships, Gastel has a clear subordinate relationship to the main antagonist, Lucifer. While the film does not elaborate on the nuances of their dynamic, several sources identify Gastel as the leader of Lucifer's demon forces, implying he holds a trusted and high-ranking position within the castle's hierarchy. He commands the respect of the lesser demons and leads their efforts to repel the intruders. His primary conflict is with Goku and Krillin, viewing them as trespassers to be eliminated. The story treats him as a serious threat that requires Goku to use clever tactics rather than sheer strength alone to overcome.

The character does not undergo a personal development arc, as his role is limited to that of an antagonist in a single film. However, his confrontation with the heroes progresses from a simple guard encounter to a prolonged aerial chase that showcases his determination. His ultimate fate serves as the conclusion of his story: he is killed not by a direct energy blast or a standard martial arts technique, but by his own relentless nature. Goku tricks him into flying into a swamp, where he is devoured whole by the mouth of a giant, unseen swamp monster.

Gastel possesses several notable abilities that make him a dangerous opponent. His primary physical capabilities include immense strength and surprising agility for his size, allowing him to wield his heavy clubs with ease and perform acrobatic maneuvers like somersaults. He has a unique weapon in the form of his floating bandage, which he can launch at enemies to slice through matter or ensnare them. His most prominent special ability is flight. By summoning two dark, nimbus-like clouds of energy beneath his feet, he can propel himself through the air at great speed, an ability that visually mirrors the Flying Nimbus used by Goku and allows for dynamic aerial combat. This particular flying technique is considered a direct reference to the Wind-Fire Wheels, a magical vehicle used by the Chinese mythological figure Nezha, who famously fought Sun Wukong, the inspiration for Goku.
