Margo Gru

Margo Gru is the deuteragonist from the Despicable Me movie, one of the three tritagonists of the Despicable Me 2 and a major character in Despicable Me 3. She is the oldest of the orphan sisters and is the brainy and sarcastic one of the trio. She wears glasses, has a brown jacket, a Lorax shirt, a black dress with pink lines on it, and red sneakers. Like the other orphan sisters, Margo has been adopted by Gru. She is voiced by Miranda Cosgrove, who also voiced Clover in Quest for Imaginationland.

Personality
Margo tends to be sensitive and straight to the point and is very untrusting of people, taking a long time to warm up to Gru, and also does not trust his minions to begin with. She is quite optimistic despite her difficulty trusting people, telling the girls that they will be happy with Gru eventually. When Gru goes after them when they are kidnapped by Vector, she is happy to see him but is still unsure whether to go back as he gave them away again, but encouraged Edith and Agnes to jump when Gru makes a heartfelt apology. She gives Gru a big hug when Gru finally kisses them goodnight, and says that she loves him, finally viewing him as a dad.

She has a sarcastic sense of humor and wit, shown especially when Gru says not to touch anything, to which she replies 'Uh huh, what about the floor?' and 'And what about the air?', and she also mocks Gru's accent. She also implies Gru is stupid when he wishes to sell cookies to Vector straight away, whereas they usually go alphabetically- "We do the A's then the B's and the C's...". She can be quite judgmental and smart. She is very mature for her apparent age. She sees through Gru's lies about his 'dog' and 'cousins', knowing that Kyle isn't a real dog at all, and that his minions clearly aren't human, marking her quite intelligent. She outsmarts Gru several times by threatening to cause him grief or bargaining with him to get her own way, one occasion where he refuses to read to them and she says they will disturb all night long. She does have a fun loving side, such as throwing toiler paper around Gru's living room, and having pillow fights with her sisters, but her highly protective nature towards her younger sisters means she must act the adult often. Margo is very good at ballet, she's the best compared to her younger sisters, and enjoys it a lot. Margo also falls for boys, which Gru is very uncomfortable with her doing.

Despicable Me
Margo Edith and Agnes are the cause of Gru to turn good, from being a superbad to superdad. Margo is one of the three girls staying in Miss Hattie's Home for Girls. She tries to act hopeful to Miss Hattie, but when she reports to her the cookie sales, Miss Hattie is angry and warns Margo and her sisters that if they don't sell enough, they will be put in the Box of Shame. She, along with Edith and Agnes are adopted by Gru. At first, she dislikes him and refuses to accept him as her new father. However, she eventually learned to get along with him, who loved her in return.

Their relationship as father and daughter is broken briefly when Dr. Nefario sent her, Edith, and Agnes back to Miss Hattie and when she is later forced to jump from Vector's ship during a life-threatening situation. Once Gru rescued her, she thought of him as a father and told him she loved him.

Despicable Me 2
The three daughters play very little part in the sequel. Margo is seen texting a friend named "Avery" by Gru. Concerned that she might be talking to a guy behind his back, he asks her whether Avery is a boy or a girl.

At Paradise Mall, Margo encounters and falls for Antonio, the son of Eduardo, much to Gru's horror. Realizing their relationship, Agnes and Edith inform him that Margo has a boyfriend, who gets angry and tries to separate the two. Margo goes on a "date" with Antonio which is stopped by Gru.

At some point later, at the Cinco De Mayo party, Gru finds a depressed Margo, who tells him that Antonio is dancing with another girl and has cheated on her. Gru then freezes Antonio with a freeze ray in return as a depressed Margo leaves. Gru also told her, Edith and Agnes to stay home, because Eduardo was El Macho. While Margo was playing a unicorn board game with Agnes, they hear a strange growling noise, and it was Kevin.
