Bela

Bela is the main antagonist of the 2015 computer-animated film, Hotel Transylvania 2, even though he only appeared near the end of the film. He is Vlad's former sidekick and Dennis's arch-nemesis.

Bela was first seen giving Vlad an invitation sent by Mavis for Dennis's 5th birthday party. By the time they reached Hotel Transylvania, Bela had sensed humans and was told to wait outside. However, after thinking that Dennis was a human, Bela had summoned his army to kill him and Johnny's relatives.

Later, he went as far as harming Winnie (Wayne's eldest daughter), causing Dennis to grow his fangs (revealing that he is a vampire) and teaching him a lesson. Throughout the skirmish, everyone else stepped in and sent the army flying away.

In the end, Bela tried to kill Johnny, but was stopped and shrunk to a harmless size by Vlad and was grabbed and licked excessively by Wayne's children.
