Oh, I always get those mixed up!
—Heather to Valerie

Heather Duncan was a secondary antagonist in Make It Pop Season 1. In Season 2, she helped XO-IQ and turned out to be nice. She is one of the cheerleaders in Mackendrick Prep and a member of the Spirit Squad. Heather is the best friend of Valerie, and is shown to be very unintelligent. She's fierce and loyal to her best friend, and will not let anyone stand in her way.

She is portrayed by Natalie Ganzhorn.


In Rumors & Roommates, she is seem walking with Valerie around the school to pass out the flyers that they have in their hands. When Valerie suggests Caleb Davis that he should get a job at Ryker's Rink, she supports Valerie by saying it is "too cool." She is later seen at the assembly complimenting Valerie after she made a cheer.

In Duet, she is seen in the girls' bathroom with Valerie, wanting to take a shower. But with Jodi Mappa, Sun Hi Song, and Corki Chang in the way, the two were prevented from doing so. Valerie told Heather that they are going to the boys' room, but Heather adds that the boys' room is "icky, yucky, gross, and..yucky." However, Valerie corrects her, and they go to the boys' bathroom.


She's fierce, snobby, and not the smartest cookie.

Heather will do anything to help her best friend, Valerie, and is very loyal to her. She even compliments her. She also serves as a partner-in-crime, helping Valerie steal Jodi's dance moves.

Though, in Potato Power she calls out Valerie when she tried to cheat in Think-Fest. When she spills the pie on Corki she tries to apologize.

Physical Appearance

Heather has long, blonde locks that are just below her shoulders. She has brown eyes, and usually wears her Mackendrick Prep cheer leading uniform when she is practicing with her team. When she is not wearing her uniform, she usually is dressed like Valerie Graves, who wears pink shirts.

Heather began to have a crush on Caleb, in the episode Get on the Bus! she forget for a minute that he's with Jodi, and she kissed him in front of Jodi's face.

But earlier before Jodi talked to her about the kiss she was seeing if she was compatible with Caleb with paper toy that is ridiculous which said it was uncertain.

Valerie Graves

Best Friend/Teammate/Roommate/Partner-In-Crime

Heather is Valerie's best friend.
