Early life
Dennis was born a year after Mavis and Johnny (his parents) got married in the second film and lived with them at his grandfather's hotel.

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 watched Kakie The Cake Monster.

Drac's Concerns
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 seems to be because he looks human, like his father then what he is a vampire like his mother.

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

Vlad's Arrival
When Vlad comes to the party after being invited by Mavis, he (who wanted Dennis to grow out his fangs as much as Drac), possessed Kakie the Monster mascot during his performance to see if Dennis' fangs would pop out from fear, but was stopped by Dracula after the possessed Kakie scared little Dennis.

Bela's Assault
Dennis finally triggered his vampire powers when he saw that his girlfriend, Winnie, was in danger. He quickly turns into a bat and fights Bela, using super strength, super speed and X-ray vision allowing her to be able to see that Bela's gang was coming. He, Mavis, Dracula and the rest of the gang fight Bela’s gang until they retreat.

Spider-Training
In Who Framed Roger Rabbit 2, Peter B. Parker saved Dennis from the big explosion in Lou's Cafe and he trains him to be a Vampire/Spider-Boy. During the Final Battle, Spider-Man, The Mask and Dennis were facing off Judge Doom the resurrected villain, Dick Dastardly and the Legion of Doom from taking over Characterville. Their plan is to save Characterville and defeat the Legion of Doom.
