Nathan Massengill, born in 1970, is an American comic book artist widely recognized for his work as a brush inker. He entered the industry in the early 1990s and quickly became a sought-after collaborator, known for his clean, expressive finishes that enhanced the work of several top pencillers. His most famous partnership was with Ed McGuinness on Marvel's *Deadpool*, where his inking helped define the character's kinetic, irreverent look. Massengill also contributed heavily to DC Comics' *Justice Society of America*, inking Dale Eaglesham's detailed pencils, and worked with Mike Wieringo on Image's fantasy series *Tellos*. His credits extend to *Marvel Adventures Spider-Man* (with Sanford Greene), *Marvel Adventures Hulk* (with Steve Scott), and runs on *Detective Comics* and *Wonder Girl*. Over a career spanning from 1991 to 2025, he has been credited on more than 130 issues as an inker, artist, colorist, or writer. Massengill’s steady hand and ability to adapt to different penciling styles made him a reliable fixture in mainstream comics, though he has not received major industry awards. He remains active, with his later work including contributions to DC’s *Wonder Girl* series.
