Mavis Dracula, the daughter of Count Dracula, is a centuries-old vampire with a pretty cool backstory. As a vampire, she's aged a bit differently than humans, and her age is a bit of a mystery. But, if we had to put a number on it, Mavis is probably over 100 years old, but looks like she's in her early twenties - talk about a monster makeover!
Now, you might be thinking, what's the deal with vampire aging? Well, in the Hotel Transylvania universe, vampires age at a slower rate than humans, which is pretty handy for looking young and undead.
