Background

Matilda was raised in a troubled blended Foster family. Her father belonged to a drug-dealing gang, while most of her relatives—including her stepmother and half-sister—regularly abused her; her four-year-old biological brother was the sole exception. Jessica encountered Matilda through a detective-agency commission and became a consistent source of care and safety for her. 92

Ye Li first encountered Matilda while she was bruised and wary near an old building. After she asked for revenge against the gangsters who had attacked her, Ye Li killed them himself. He subsequently welcomed her into his household as his younger sister, where Jessica and Felicia also accepted her. 92 94

Appearance

Matilda is portrayed as a young teenage girl, usually dressed in casual clothing and brown boots. 99 100

• Often carries the dark-silver Meow-Meow Ball in her hands. 118 119
• Later carries the glowing White Lightsaber. 133 134
• Has appeared in a Knightress-style disguise while operating during the Chitauri invasion. 139

Personality

Initially timid and guarded, Matilda becomes visibly happier and more innocent around Jessica, whom she trusts as an older-sister figure. 92 Her traumatic upbringing gives her a strong desire to become powerful enough to protect vulnerable people in the slums. 98 99

Matilda is courageous but initially inexperienced in major superhuman battles. She willingly confronted the Destroyer with Mjolnir, though she was ultimately overwhelmed by its superior combat power. 108 She also has a rebellious streak, particularly regarding cigarettes and sneaking out, but generally listens when Ye Li sets boundaries for her. 134 139 157

In later appearances, she is more playful and self-assured, though she can become uncomfortable when she feels overshadowed within the household. 269 293

New Mexico and Mjolnir

Matilda received the Super Soldier Serum before accompanying Ye Li to New Mexico, where she learned that she was Jane Foster's cousin. She then became unexpectedly worthy of Mjolnir, making her central to the conflict surrounding Thor, Loki, and the Destroyer. 99 102 106 108
