Siegbert is a friend of Mayuwih, Lugeloo, and Cahiley. He was created when a cloning machine ingested Squilliam Fancyson's DNA. Siegbert was kidnapped by Punilac's father Brutilac at a young age, but he was rescued by the police. Back then, DNA technology wasn't very good, so the police couldn't identify Siegbert's parents. Because of this, he was put in an orphanage. Years later Siegbert was taken to work by Lugeloo, and he took Siegbert out of the orphanage. Siebert now spends his life as a receptionist at Mayuwih's mansion.
