Nasthalthia

Nasthalthia is Lex Luthor's niece, a scheming antagonist who repeatedly clashes with Supergirl. Inheriting her uncle's contempt for Kryptonians, she relies on cunning and her Luthor family connections rather than any powers to pursue her grudges.

Nasthalthia made her entrance in the Bronze Age pages of Adventure Comics #401 (1971), brought to life by Mike Sekowsky, and has proven a quietly enduring figure in DC's universe across more than five decades. She moves in rarefied company — sharing pages with Superman, Lex Luthor, Lois Lane, and the rest of Metropolis's finest — which speaks to the heavyweight corner of DC lore she inhabits. Her appearances in All Star Superman in particular place her within one of the most celebrated runs in modern DC history, lending her a genuine key-issue cachet that collectors have good reason to notice. Rare in count but rich in context, Nasthalthia is exactly the kind of deep-cut character who rewards the curious fan willing to dig.
