Eusine was born in the city and when he grew up, he took over the sarcastic personality from one of his friends who lives near him. Eusine is rather befriended with boys than with girls. As a baby, he came into music and because Lord Tourettes is one of his friends, they both learned how to play guitar at age 2. Now that Eusine is popular because he plays the guitar for like 10 years, he is a rich person and a chick-magnet. He is also very short-tempered and very bad with computers and other devices, and that's also a reason why he hates smartphones, tablets, etc.
His voice is exactly the same voice as the one of Glenn Quagmire from Family Guy, although Eusine doesn't have a habit of saying "Giggity" like Quagmire does.
