Berdly is sarcastic, arrogant, and considers himself one of the smartest students in his class. He shows disdain towards his peers who are “lower IQ” than him, but has respect for Noelle, whom he considers the smartest in class. Despite his ego, he’s not as smart as he says he is. Berdly is also a huge video game nerd, but despises mobile games.

Berdly has a medium-to-high pitch voice, with a bit of nasal to embody his sheer nerdiness. His tone is not meek--he's a gamer with pride, and he speeks loudly, proudly, and clearly.
