Piper Hart (Close Friend)
Swellview Junior High (Possibly)
Marla has light brown/blonde hair, similar to her friend Piper, and brown eyes. She may be the unofficial "Vice President" of the Man Fans as she has shown being capable of giving instructions to the other Man Fans about Captain Man and Kid Danger's decision on which frittles they will vote for. She likes to chew gum in her mouth.
In The Trouble With Frittles, at a Man Fan meeting at Piper's house, Marla reminded everyone the reason they're all present was who would vote for their favorite flavor of Frittles. She asks Oliver Pook why he is even friends with Sidney Birnbaum, after the latter proposed having a caucus instead of relying on the decision of Captain Man and Kid Danger, much to the disappointment of her and the other Man Fans.
She later appears at the Frittle Factory in Swellview with the Man Fans, who announce their presence to the heroes there. Jack Frittleman asks if the Man Fans are here to see the Frittle Blimp, which Marla quickly denounces that kids hate blimps. When they ask which Frittle flavor they should vote for, they unfortunately witness the heroes get into a fight over their favorite flavor. Due to the heroes' fight, Marla, Piper, and the Man Fans flee the factory before it explodes.
- She was mentioned numerous times before finally appearing in A Fiñata Full Of Death Bugs.
