Mavis Dracula

Mavis Dracula Loughran is the deuteragonist of the Hotel Transylvania movie series. She is the Vampire daughter of Count Dracula and Martha of Lubov Castle. In the first film, she is 118 years old and meets Jonathan Loughran. In the second film, she gives birth to Dennis. By the time of the third film, she has become a busy worker for the hotel and still continues to live with her family there. She has been described as being 126 years old as of the 3rd film, implying 8 years have passed since the first film.

Age
She turns 118 in the first film.

Although this is not present in the dialogue of Hotel Transylvania 2, its novelization by Stacia Deutsch includes added dialogue indicating how old Mavis is (probably 119) as she prepares to wed Johnny:

page 3: "Daddy, I love him so much, but am I doing the right thing? He's my zing, but I'm so young! I'm still just a hundred teenager!" page 4 "Girls mature faster," Dracula told her. "And you're practically a hundred and twenty." Chapter 2 begins "A few years later" (minimum 2, so Mavis must be at least 121 years old) and is when Mavis announces her pregnancy to her father.

This means that by the time of the end of the film when Dennis turns five, Mavis must be at least 126 years old.

In one of the earlier drafts, Linda commented "you’re a hundred twenty something!" but this line was cut from the final film.

Physical Appearance
Mavis is a beautiful and slender pale-skinned vampire with shoulder-length black hair that has bangs hanging over her forehead and wide blue eyes. She usually wears a black turtleneck dress with long black fingerless gloves, black and red striped tights and red Converse shoes. Either her makeup or her natural features portray her with black lips, lined eyes and dusky eyelids.

Personality
Mavis is a headstrong, intelligent, curious, cheerful and independent vampire who has an attitude, but she is very sincere and gentle. She wants a little bit of independence and freedom from her father's overbearing nature and frequently gets bored with his ministrations. She dreams of exploring the world and experiencing all the sights and sounds that the world has to offer, but all that becomes a reality when she meets Jonathan and falls in love, or zings, with him before discovering he is human. She also has a caring nature, no matter how horrible the circumstances. When she was in the fake human village her father created, she was worried about the false humans who were on fire even though they were attempting to physically injure her.

In the second film, after becoming a mother, Mavis begins to adopt some of her father's over protectiveness and attachment to her child. She takes extreme measures for his safety rarely leaving his side and wanting to move to California in order for her son to grow up in a safe environment and around other children like him. Unlike her father she doesn't seem to care that Dennis isn't a full vampire and accepts him for who he is, even standing up to people who she assumes are prejudicing him for being a hybrid. Though she also seems to want him to be human.

However, she does still show some carefree habits in her later years, such as destroying a piñata, gorging herself on a slushie, and performing bike tricks.
