  —Uncle Frank on the barbecue [src]  

Uncle Frank is Erica Wang's uncle. He is an African-American man possibly in his 30s to 40s. Due to his race, he may be on Erica Wang's mom's side of the family.


The Epic Tales of Captain Underpants[]

He is a minor character in The Trashy Tale of the Tumultuous Tubbadump, only appearing in a flashback when Erica questions why she celebrates Labor Day by letting Uncle Frank burn a perfectly good steak, which then proceeds to show Uncle Frank doing exactly that. He made his last appearance in The Hazardous Hysteria of the Hangry Hypnosinger in the Burger Flip-O-Rama (the O-Rama of the episode), where he is voiced by Sean Astin, who also plays the narrator. In that episode, he is called Uncle Dan.
