Jack of Hearts (New MCU)

Jack of Hearts (Jacqueline Hart)

Portrayed by Jodie Comer

Jodie Comer ignites the screen as Jacqueline “Jack” Hart, the New MCU’s Jack of Hearts. Once an ambitious physicist, an accident with zero-point energy left her body infused with volatile cosmic power. Bound in an armored containment suit laced with circuitry and heart-shaped channels, Jack of Hearts must constantly regulate the unstable energy that fuels her strength — and threatens to burn her alive.

Comer balances vulnerability and intensity, making Jack both tragic and formidable. She’s not a clean-cut Avenger but a woman driven by control and survival, knowing one wrong surge could reduce her allies to ash. Her look — ornate armor glowing with crimson pulses — reflects her double life as both a scientist seeking solutions and a warrior wielding cosmic destruction.
