Marlena Gru

Marlena Gru is Felonius Gru and Dru Gru's mother, Lucy Wilde's mother-in law, Robert Gru's wife, and the adoptive paternal grandmother of Margo, Edith and Agnes. She is a minor character in Despicable Me, and has done two silent cameos in Despicable Me 2 and Minions.

Appearance
She is short with a prominent chin and a tall beehive-like hairstyle. Despite her size, she is also very strong and skilled in karate, being capable of kicking a punching bag with so much force that it knocked her karate instructor across a room. She has a long nose that is typically seen throughout the Gru bloodline.

Personality
Marlena Gru is rather neglectful of her son and had a tendency to be rather nasty to him. She ignored him in his childhood, though she did seem mildly impressed by the rocket he built. She is unimpressed by most of Gru's accomplishments, but eventually grew proud of him when he showed her what a great parent he is. She is also ignorant of her own lack of skill at parenting, thinking that she is a great parent, though she did admit to Gru that he might be slightly better than her, which somewhat touches him.

Despite her neglect towards her own son, Marlena took a liking to his adopted daughters and showed them pictures of Gru as a child because she wanted to. She also never had anyone to talk to for a while.
