Due to a youth filled with disappointments and rejections, Andy has trouble trusting other people and may appear shy and ill-mannered. He also lives in constant fear of his beast side being unleashed, which he thinks makes him a danger to others. Since befriending the Monster High students, he has been gaining confidence, but it's still a way to go before he'll have dealt with his insecurities. Andy presumably is from around the 18th century and has been living alone on Skull Shores since that time. As a result, he is unfamiliar with modern technology and easily freaked out by it.
