This is something that was unexpected. The Transformers Collaborative line started in 2019 with the release of repaints homaging pop culture characters/movies like Ghostbutsters, Back to The Future and few others. However, it's possible that the Universal Monsters crossover won't just be a one-off release but with many more to come, focusing on horror/monster characters from Universal Studio.
The first release, Draculus, is based on Universal Monster's Dracula. I believe it is based on 1931 Dracula, starring Bela Lugosi
