Vandora is a female vampire that was the main antagonist to the film Dr. Slump and Arale-chan: N-cha!! Trembling Heart of the Summer. She ran a ghost hotel with a bunch of her monster underlings and captured all of the guests in order to suck their blood. Wanting to start with Arale, she took a bite from her, but her fangs broke since she did not know Arale was an android. When she was defeated, she was shown to reform and seen dancing happily with the other monsters and the guests from Penguin Village.
- She seems to be a replacement for Trampire in the Dr. Slump and Arale-Chan Reboot film series since Trampire does not appear in that continuity and that Vandora seems to have many similar traits to her. She also looks like the female vampire from the chapte "Hello, Wonder Island", in her manga version.
