Dennis

Dennis (voiced by Asher Blinkoff) is the half-human/half-vampire son of Jonathan and Mavis, and the main deuteragonist in Hotel Transylvania 2.

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). While born showing no vampire traits, by his fifth birthday, he finally grew his fangs and likewise manifested his vampire abilities. Dennis is kind, innocent, funny, silly, shy, odd, cowardly, hyperactive, loveable, and different but at the end of the film, he becomes brave, silly, hyperactive, optimistic, kind, funny, monster-loving.
