X-Factor #19

In "All Together Now!", Apocalypse tests his Horsemen's unity by unleashing them on X-Factor, forcing the team into a brutal clash that leaves Beast dangerously ill after Pestilence's touch. As the fight rages through Central Park, Iceman's powers leave a frozen swath in the heart of the city, turning the urban landscape into a battleground. Written by Louise Simonson and illustrated by Walter Simonson, with inks by Bob Wiacek, colors by Petra Scotese, and letters by Joe Rosen, this 1987 issue features a cover by Walter Simonson that captures the chaos in bold, dynamic strokes.
