Inertia

Inertia is a superhuman character who appeared in Mark Gruenwald's Squadron Supreme, a series exploring a parallel-Earth team of heroes. She possesses the ability to manipulate inertia, and is associated with the morally complex world of that universe's superhero community.

Emerging from Mark Gruenwald and Paul Ryan's landmark Squadron Supreme series in 1986, Inertia is a Copper Age Marvel creation with roots in one of the era's most ambitious and morally complex superhero narratives. With a modest but meaningful footprint across nearly 25 years of publishing — touching Squadron Supreme and Supreme Power alike — this character keeps rarefied company, sharing pages with the likes of Hyperion and Nighthawk in stories that pushed the boundaries of what superhero comics could say. A rare presence rather than a household name, Inertia is exactly the kind of discovery that rewards the dedicated reader who digs deeper into Gruenwald's rich, thoughtful corner of the Marvel universe.
