Barb is a muddy red-skinned Rock Troll with a bright red mohawk. Her left ear is missing the tip and she has a hoop earring in it; on her other ear are two earrings. She has heavy black makeup around her eyes. Her red hue and bright hair makes her a lot more distinct from other Rock Trolls, who are mostly colored in greyish tones with either black, white, grey, dark red or blond hair. She's in fact one of the most colorful members of their Tribe. However, her colors seem a bit inconsistent, like Branch's, going between a darker pinkish red/lavender and a muddier red. Similar to Branch as well, her hair is actually short for a Troll of her size.Barb is a muddy red-skinned Rock Troll with a bright red mohawk.

This includes fishnet stockings with a rip on the right knee, a torn-up white tank top, black leather bottoms, studded bracelets and a silver belt with a skull buckle.Queen Barb is shown to be a zealous hard rocker at heart, who loves the members of her Tribe and her music. Even though she mostly shields herself with a rough exterior, Barb actually has a softer side that she mostly expresses around the kids in her Tribe (she is seen rocking with Amp during Crazy Train); she also cares deeply for her senile father, and her pet bat Debbie, whom she calls her "hairy little baby". Barb appears to have a more realistic perspective of friendship and believes that one can't just become best friends all of a sudden, but rather friendship takes time with mutual care and respect. But judging by how the other Rock Trolls treated her (as their queen and leader and not as a fellow Troll to befriend), it seemed that she was Her more realistic approach to the world lets her see how the Tribes were different, which was a stark contrast to Poppy who believed everyone was the same, but she didn't see how this was positive. Instead, she saw the only way to unite the Trolls as being under one music, which she believed should be her own music: Rock. Her plans proved to be far more insidious, as she planned not only to eradicate all other kinds of music except Rock, but to turn the other Troll Tribes into "Rock zombies", using the Rock string to overwrite their true nature and force it to be dedicated to Rock. Although Barb thought her actions were righteous and for the greater good, she casually admitted her goal was basically world domination, and called it fun.
