While you could potentially use "succubic" or "succubus-like", these are not standard English words and may not be easily understood by everyone.
To describe something related to a succubus, it's generally better to use descriptive phrases, such as:
* Succubus-inspired
* Succubus-themed
* Having succubus qualities
* Demonic
* Seductive
* Nightmarish
For example, you could say "The painting had a succubus-inspired theme" or "The character was a demonic and seductive being."
