Heidi is an Inhuman, like her relatives. As her sister as psionic abilities, and her brother has elemental abilities, Heidi has physical abilities, which includes: * Superhuman Strength: The upper limits of her powers are unknown, but she can hold her own against the Hulk. Heidi can topple monsters as large as skyscrapers, tunnel through miles of rock, and lift tons with ease. * Invulnerability: Heidi has some level of invulnerability, though she is not invincible. * Bioluminescent: When Heidi's strength increases, her eyes glow purple. Sometimes, she also emits a purple aura.
