Bela

Bela is Vlad's right-hand man, leader of his Bat Cronie Army and antagonist of Hotel Transylvania 2 (2015).

Personality
Unlike his master, Bela is shown to be energetic and easily worked up for little to no reason. He is prone to going into a rage whenever the slightest bit of news is made and has to be told to stop shouting by Vlad. He seems to possess a deep-seated hatred of humans, taking matters into his own hands and calls upon his bretheren, hunting down Dennis and Winnie with intentions of eating them.

Powers & Abilities
It could be assumed that, like other monsters, Bela is essentially immortal.
