Austin is outgoing, super talented, and somewhat naive, but often nice. He can sing, dance, and play all sorts of instruments. Overnight, he becomes an internet sensation by singing one of Ally's songs in a music video directed by Dez. With his friends' help, Austin is following his dream of making it in the music business and so is Ally. Austin sings the songs that Ally writes for him. He is shown to be a slight airhead. He also seems to love stuffed animals. As well as very calm, cool and collected, he is more of a fun person, who doesn't care about rules (demonstrated when he colors outside of the lines in a coloring book). He's also shown to be quite caring, and a brave person.
