|Occupation|| A Capella singer|
|Member of||The Treblemakers|
|Portrayed by||Gregory Gorenc|
Treblemaker #3 was never given an actual name throughout the entire film but is typically referred to as the name "Greg" by fans. He is a very enthusiastic member of the all-male a cappella group, the Treblemakers, in Barden University and appears to get along with his fellow members very well.
Greg has been attending Barden University for an unknown length of time, although it is obvious he is at least a year or two from graduation, as he was still a member of the Trebles at the end of the film as the new auditions were being held. Throughout the whole film, he was mostly a background character and had no actual dialogue except for doing back-up singing for the Treblemakers performances.
He seems to be very enthusiastic and happy throughout the film, also a bit competitive towards the Bellas as most of the Trebles are. But we could see that Greg in the movie is a humble person, he is not arrogant (although during the new auditions at the end of the movie, he is seen rolling his eyes as the Bellas are introduced as the current champions).
He was not seen talking to any of the Bellas but was seen walking behind Stacie at the aca-initiation night then she turned around and did a hand gesture at him.
He is easily distinguished in the Trebles because of his hair, which is bleached bright blonde in the front as it fades to a more brown color, and he has a very distinct smile. He also has a very fair skin tone and light greenish blue eyes that stand out.
