Mommy, are we going away because I'm not a monster?
— Dennis asking Mavis why she wants to move

He is also the grandson of Dracula and Martha (his maternal grandparents) as well as Mike and Linda (his paternal grandparents). Through Mavis, Dennis is also the great-grandson of Vlad (his mother's paternal grandfather). It is unknown whether he will get his father's mortality or his mother's immortality, but he might live slightly longer than true average purebred humans, but having vulnerability to death, as a combination of the two.

Official Profile Edit

Appearance Edit

Dennis is a little boy with unruly, striking red hair and blue eyes, a combination of genes he inherited from both his parents. He is dressed in a sports jersey with the number "4" on it and shorts similar to Johnny. According to creators Dennis inherited Mavis's striking eyes and Johnny's bright hair.

Personality Edit

Dennis is outwardly portrayed as being optimistic and childish such as any child is age. He appears to have a fairly similar temperament to Johnathan: easygoing, insouciant, and exuberant in most scenarios. Aside from his high-spirited demeanor, Dennis has substantiated noticeable signs of maturity for his age - even as a five-year-old he finds himself too old for any childish needs Mavis attempts to provide him with. Overall, he is rather naive about certain things; he expressed a large amount of naivety when he lacked any sort of monstrous abilities. Initially, Dennis is unaware that his lack of vampire skills was an immense problem and would impact him negatively; when he is exposed to the realities of the world, Dennis began taking this fact more seriously, attempting to become a vampire in order to remain at Hotel Transylvania.

Biography Edit

Hotel Transylvania 2 Edit

Early Life Edit

Dennis was born 2 years after the events of the first film (June 13th, 2014) to Johnny and Mavis and lived with them at his maternal grandfather's hotel. According to Mike (his paternal grandfather) Dennis was named after Mike's father (a great grandfather).

According to the height chart, "DENNiS 1 YEAR!" was taller than "Mavis year 1", but "DENNiS 2 YEARS!" was not as tall as "Mavis year 2".

As he showed a lack of vampire traits, he was raised mostly human, being fed healthy foods and taught by his parents. He often played with the Werewolf kids, and he loved to watch Kakie The Cake Monster's show.

Drac's Concerns Edit

Due to his heritage and possibly his young age, Dennis shows no signs of becoming a monster much to the distress of Dracula. Dennis' lack of powers seem to be because he looks more human like his father than his vampire mother.

Monster Training Boot Camp Edit

After Mavis and Johnny head to California to visit Dennis' paternal grandparents, Mike and Linda, Dennis is left in the care of Drac and his friends Wayne, Murray, Griffin and Frank. Though, unknown to Mavis, Drac wanting to bring out Dennis' monster genes decides to recruit his friends into putting the little boy through a monster training boot camp. 

First, Drac had Frank show Dennis how to scare people by jumping out and scaring two joggers. However, the joggers recognize Frank and ask to take a selfie with him instead. Dennis tries to jump out and scare them, but they just think he's adorable. Next, Drac has Wayne show Dennis how to eat an entire deer, but Wayne, being the old wolf, forgets how to attack the deer and instead chases a frisbee a nearby human threw for his dog. Finally, Drac asks Murray to conjure up a huge sandstorm to show Dennis how to be a ruthless monster. However, as Murray is performing his spell, he throws out his back and only summons a small amount of sand in which Dennis begins to play in and makes a snowman out of. 

When all else failed, Drac decided to take Dennis to his childhood camp, Camp Winnepacaca where he learned how to use his vampire skills as a kid. However, the trip did not help Dennis as the camp was under new management, and was "too safe". Drac throws Dennis off a tower to teach him how to fly, but Drac has to save Dennis from falling to his death. The tower collapses under the combined weight of Griffin, Wayne, Murray and Frankenstein's monster, setting the camp on fire. Mavis was extremely mad and upset when she heard what Drac had done and felt that Drac had betrayed her trust (she had placed Dennis under Drac's care while she went to visit Johnny's hometown), prompting her to seriously consider moving. 

Vlad's Arrival Edit

When Vlad comes to the party after being invited by Mavis, Johnny has to don a vampire costume. Vlad exclaimed that Johnny's wig looked like "his great-grandma's boobies" but seemed to believe the facade. Upon learning that Dennis was a late-fanger, he volunteered to help Dennis to grow out his fangs. He explained that what he needed to do was take something that Dennis found sweet and innocent (Kakie) and twist it into something terrible. Vlad possessed Kakie the cake monster mascot during his performance to see if Dennis' fangs would pop out, but was interrupted by Dracula as he saw what a traumatizing effect it had on Dennis.

Bela's Assault Edit

Dennis vs Bela

Dennis' vampire side unleashed.

Dennis becomes upset over the arguments between the adults and runs into the woods. Winnie follows him and leads him to her hideout. Bela, who had discovered that Dennis has human blood, tried to kill Dennis, but Winnie got in the way. Bela hits her and Winnie whimpers on the ground. Dennis was enraged and his fangs finally popped out. He quickly turns into a bat and fights Bela, followed by super strength and super speed and enhanced vision allowing him to be able to see that Bela's gang was coming. After Dennis and the rest of the group defeat Bela and his army, Dennis asks Drac if he's cool now. Drac reassures Dennis that he was always cool, and that he is perfect no matter what.

Aftermath Edit

Dennis' birthday cake

Then Dennis and his family go back to the hotel to continue finishing his 5th birthday party. Dennis is seen dancing with his father Johnny, his mother Mavis, and Winnie. Dennis then freezes Linda in place. Dennis is last seen dancing some more with Winnie. Just then, Dennis sees his birthday cake and flies up to blow the candle out on his birthday cake, however, just as he about to blow out the candle on his cake, the Elderly Gremlin eats his entire cake which stuns Dennis as the Elderly Gremlin says she didn't do it.

Hotel Transylvania 3 Edit

Family and Friends Edit

MileyCyrus-Mavis 320

Mavis, Dennis' mother

Mavis Edit

Mavis is Dennis' mother. She's shown to be very protective of her son, such as making her dad babyproof the entire hotel and even going so far as to consider moving out of the hotel to a place that would probably be safer for Dennis to live (unaware that Johnny, like Dracula, is against it, and also that Dennis is against it too). Due to Dennis' human heritage and lack of any monster abilities, she only feeds him healthy human food, mostly avocados, and has him sleep most of the night. She first appears in the second teaser trailer for the second film putting Dennis to bed when Dracula pops up, saying that the lullaby she is singing is incorrect.

Jonathan

Jonathan, Dennis' father

Jonathan Edit

Jonathan is Dennis' father. Johnny cares for his son like any other father would, but still maintains his slacker attitude. In contrast to Mavis, who inherited Dracula's over-protectiveness, Johnny's concern is on a normal level; such an example is that she freaked out over Dennis losing a baby tooth. Due to how much he loves living at the hotel (which doesn't require him to have an actual job to provide for his family), Johnny is willing to cooperate with Dracula to train Dennis as a monster. Unbeknownst to both is that Dennis loves living at the hotel just as much, and hates the idea of leaving.

Dracula Edit

Drac welcome

Count Dracula, Dennis' grandfather

Dracula is Dennis' maternal grandfather. Since Dennis was born, Drac vowed to always protect him. Dennis likes his "papa Drac", who often amuses him by causing self-harm. Dracula has been waiting for the day Dennis gets his fangs, but becomes concerned as his 5th birthday nears, which is when the chance completely vanishes. Dennis is taken to various spooky places by his grandfather, to inspire his inner monster to surface. In the movie, Drac is all for Mavis and Johnny to go visit Johnny's parents in California so when they leave, Drac and his friends put Dennis through "monster training boot camp"

Martha Edit

Martha is Dennis' maternal grandmother. Due to the fact that Martha got killed by a mob of angry humans when Mavis was a baby, Dennis never met her. She was mentioned by Dennis when he asked Dracula if he missed her.

Vlad Edit

VladHotelT

Vlad, Dennis' great-grandfather

Vlad is Dennis's maternal great-grandfather. When Vlad finds out that he has a great-grandson, he goes to the hotel and when he sees Dennis still doesn't have his fangs, he thinks he is a "late fang-er" like his son Dracula. So Vlad tries to "scare" Dennis's fangs out by possessing Dennis's favorite monster Kakie the cake monster. Vlad at first rejects accepting Dennis for who he is, (half-human), but after seeing Dennis defend his family and friends from Bela, he learns that it doesn't matter that he's part human and accepts Dennis as a part of the family. 

Frank, Wayne, Murray, and Griffin Edit

In the second film, it is shown that Dennis has a nephew/surrogate uncle relationship with his Grandfather's friends. In the first teaser trailer for Hotel Transylvania 2, the four were genuinely concerned when Dennis didn't fly after Dracula tossed him over the tall tower during part of his monster training, and until Dracula actually saved Dennis from hitting the ground, they kept pointing out how Dennis wasn't flying and kept urging Dracula to get him, and 

Murray got freaked out when Dennis started getting too close to the ground.

Winnie Edit

Wayne and Wanda's well-behaved daughter. She is Dennis' friend, though she considers him her zing. Her normal greeting is pouncing on Dennis and licking him. She considers him the kindest boy she knows due to her unruly brothers usually causing havoc and chaos. Dennis claims that they are just friends, but despite this, it's possible that he likes her more than a friend as seeing Bela hurt her was enough for him to gain his vampire abilities and defend her.

Mike and LindaEdit

Mike&Linda

Mike and Linda are Dennis's paternal grandparents. They love Dennis, but like their daughter-in-law, Mavis, wonder if it Hotel Transylvania is a safe place for him to live, mostly due to his lack of monster abilities.
