"I have no gene for giving a damn" Monse

"Monse Finnie" is the primary protagonist on the Netflix series "On My Block".

She is portrayed by Sierra Capri.

Character Description

Monse is a headstrong, bossy girl of Afro-Latina descent. She was raised by her single father.

Monse is a selfless, outspoken girl who will do anything to keep her friends together. She will always put the needs of others before her own. She is truly the glue that kept the 'fam' together.

She hasn't had a female role model in her life which is why she has no idea how to do her hair or wear dresses.

Physical Appearance

Monse has curly black hair, which she usually wears with a little bit of it clipped to the back and the rest down with the exception of Chapter Ten, in which she flat ironed it.

She has pierced ears with a second piercing on top of her right ear. She has brown eyes and is built very slim. At the beginning of the series she had braces, but they were removed over the summer. She is also shown to wear a ring on her right hand.


Monse is brutally honest and has no filter. She is very bossy, and Cesar calls her a "honey badger" because of it.

She is very headstrong and determined, as shown by her mission to try to get Cesar out of the Santos. She is not very forgiving - once you offend her it is on. Monse is an 'all or nothing' kind of person. Although she is strong she can be quite sad at times.

When her suspected mother was reading to the kids Monse was babysitting she broke down in tears. Showing that after all, she really does have feelings. She is a daddy's girl.

Monse's mother left when she was young and she isn't very feminine. Monse doesn't like that she doesn't know how to be girly. She also has a soft spot for Cesar. When she lied about what happened in the summertime and broke it off with Cesar, you could see a tear running down her face.

She also breaks down in her father's arms after their breakup. Monse is defined by her loyalty. She refuses to be with Cesar despite her feelings for him because she wants to remain loyal to the 'fam' and she doesn't want to ruin their relationship.

Throughout the Series

Through the series, Monse becomes more feminine and shows her emotions more. She becomes more in touch with her emotions and we see more of the relationship between herself and the people around.
