The character was introduced in the third season in the episode Nerdson, as Gui's unpopular nerdy neighbour and as his "new friend". His second appearance is in the episode Escola em Casa.
Why He Should Be Sent To Mental Hospital
To start in, Nerdson himself is just a huge stereotype about loser nerdy boys (starting with his stupid name), and also.. what kind of name is Nerdson anyway?
This might be his nickname or his own mother doesn't have creativity for give names, if it's was the first case, what's his true name?
He just acts like a big jerk to Gui not only invading his privacy in his house, but also taking embarrassing photos of him and threatening to post them on social media if Gui doesn't obey Nerdson's requests to be his friend and help him get popular at school.
He also has a very lazy and uncanny design, probably the most poorly drawn character on the show. The same can be said about the costumes he and Gui wear at the costume party.
He was never punished for what he did with Gui in his debut episode.
He is also very unlikable in his second appearance in the episode "Escola em Casa".
Like most of the characters on the show he has a really annoying voice.
