Veronica seems to have incredibly bad luck, which seems to have been inherited from her father. In most episodes, she's either humiliated, put in pain, or snubbed. While she is a popular kid, Trixie treats her as an inferior. Even Timmy doesn't seem to have much respect or sympathy for her until "Second Rate Popular Birthday". Ivan Prestonovich, Veronica's first love interest, is one of the few unpopular kids who feels sorry for her. There are times where she wishes she was Trixie. Veronica is also secretly in love with Timmy, and sometimes dates him.
Veronica is blonde-haired with her hair held back in a ponytail. She usually wears a cheerleader outfit with a pink skirt, pink boots, and white shirt with a "D" (for Dimmsdale) on the front. For bedtime, her pajamas are colored purple. She is taller than the other students in her class, and is around the same height as Trixie. As a teenager, her voice sounds similar to Jackie Lynn Thomas from Star Vs. the Forces of Evil. As an adult, Veronica's voice is slightly deeper.
Veronica is described as "popular but less popular than Trixie Tang". In many cases, she is treated poorly by the other popular kids, and, prior to meeting Ivan, not many of the unpopular kids seem to like her either, usually because she does not call them by name but rather addresses them as losers or "not populars". It's not known how she feels about Timmy's crush on Trixie Tang, over than that Veronica wants to be Trixie Tang so that Timmy will love her instead, but Timmy considers her crazy for this very reason. Over time, however, Veronica learns to accept that Timmy likes Trixie more than her, but Timmy still loves Veronica, and even considers her a fine replacement for Trixie. Sometimes, Veronica forms a rivalry with Tootie, as they both have a crush on Timmy. In the episode "All-In-One Romance", it's revealed that Veronica speaks Russian. Veronica also loves cats, and got excited when her boyfriend gave her a cat for her birthday.
In the episode "A Mile In Popularity's Shoes", when Timmy Turner switched lives with Trixie Tang, Veronica is more lucky, since she has a crush on Timmy Tang, who is not only popular, but he also loves her back. Unlike in Timmy's home universe, Veronica doesn't get mad when Timmy falls in love with another unpopular girl, like Trixie Turner.
