In the first movie she is portrayed by Jennette McCurdy, but in all subsequent appearances she is played by Daniella Monet.

Physical Appearance
In the first film, Bertha has black hair and blue eyes. In later appearances, she has dark brown hair and brown eyes.

Bertha typically dresses in a goth/scene fashion; she wears lots of patterns and colors as well as lots of jewelry and accessories. She also dyes parts of her hair in various colors and wears it in different styles.

History
In the web series, Bertha is a girl that Fred meets in "Fred Meets Bertha," by virtue of their moms being drinking buddies. She is supposedly pretty and is a popular second grader at Fred's school. This was her only voiced appearance in the web series.

Bertha was mentioned in "Fred's Mom Returns", when Fred recalls when they were playing in her basement and pretending to be living underground-- and she manages to scare Fred in the dark.

In the movie trilogy, she has a bigger role as Fred's best friend and accomplice to his plans. In the first movie, she helps him create the illusion of a big party to fool their peers. In the second movie, she assists Fred in trying to prove Mr. Devlin is a vampire and later trying to convince everyone that Fred was the vampire.

Personality
In the web series, Fred says she's nice to him. However, she also appears to be a troublemaker that tells Fred to do bad things, like throwing a beer bottle at a car and pushing an old guy in a wheelchair into a wall ("Fred Meets Bertha").

In the movies and the TV show, she is shown to be cynical, sarcastic, and has a dry sense of humor. She also does not seem to care about what anyone thinks. Bertha is also shown to be more of a logical and competent person, managing to disguise herself convincingly as a waitress in the second movie when they were following Mr. Devlin and having a backup plan for when her and Fred's home ec project was ruined.
