The Doraemon franchise have multiple movies with main villains menacing the heroes, and a secondary henchman (or henchmen) for carrying out their orders:
Doraemon's Long Tales
- Doraemon: Nobita's Dinosaur: Black Mask, the ringleader of the Dinosaur Hunters who serves the main villain, Dolmanstein, who had his eyes on Nobita's new pet futubasaurus Piisuke. Then again Black Mask actually debuts in the story before his boss Dolmanstein (a whole hour in the anime films) and is the main antagonist Nobita had a beef against.
- Doraemon: The Record of Nobita : Spaceblazer introduces it's dragon more than halfway through, with the first half having Nobita and Doraemon dealing with the Bumbling Henchmen Duo, a pair of incompetent Gartite enforcers called Uno and Doubt. Then the dragon, Guillermin, shows up and is a powerful Knight of Cerebus that actually gives the heroes trouble, even coming close to killing Doraemon and Nobita if Shizuka didn't convince Gian and Suneo to travel to Planet Koya Koya to pull a Big Damn Heroes on time.
- Doraemon: Nobita and the Haunts of Evil: There's a pair of Co-Dragons serving the villain Minister Daburanda of Bauwan, the Mad Scientist Evil Genius Professor Kos who uncovered and recreates the ancient Bauwan war machines and Captain Saber, the Mook Lieutenant who leads Daubranda's army.
- Doraemon: Nobita's Great Adventure into the Underworld: Demon Lord Demaon's henchwoman Medusa, though her role is rather small in the original manga (appearing once to pursue Doraemon and Nobita, then leaves). The 2007 remake turns Medusa into an Ascended Extra and the film's secondary antagonist, and also the revelation that she's actually Miyoko's mother, converted to a monster to save her child years ago.
- Doraemon: Nobita's Little Space War: General Gilmore's Number Two, Colonel Dracorl who leads the hunt after President Papi who turns out to be scarily competent at his job, from stealing Doraemon's Shrinking Light causing the heroes to be stranded in their smaller forms and kidnapping Shizuka to force Papi's surrender. In the 2021 remake however Dracorl turns out to be far more honorable than his boss, asking for his mooks to be spared after his defeat unlike Gilmore who abandons his army to flee.

Depending on the adaptation, Tsuchidama either gets demoted to a mook (original manga and anime) or melted into a puddle by Gigazombie over his failure (2016 remake).
- Doraemon: Nobita's Dorabian Nights: The "Arabian Nights" Days-themed crossover has Cassim from Ali Baba and the Forty Thieves being the subordinate of the film's main slaver antagonist, Abdil.
- Doraemon: Nobita's Three Visionary Swordsmen: Demon Lord Odorom have multiple dragons serving him, his direct subordinate Toriho being the most prominent (since it's Toriho who succeeds in dragging Nobita and friends into the Dream World of Yumemiru to be eliminated by Odorom). There are also two other demon generals, Spider and Ganbosu leading Odorom's army in terrorizing Yumemiru.
- Doraemon: Nobita and the Galaxy Super-express: An unintentional example, but when the Yadori Aliens - a Puppeteer Parasite race running an Assimilation Plot - attacks, they infect one of The Team, Suneo, and the new character Aston, turning them into their minions for manipulating the gang for ease of capture and assimilation.
- Doraemon: Nobita's Great Adventure in the South Seas: The billionaire Mr. Cash runs a black market selling genetically-modified hybrid monsters in The Golden Age of Piracy, with his main dragon being Dr. Clone, an Evilutionary Biologist.
