From IDW Publishing and Boom! Studios, two titanic powers collide in a cross-company collaboration event you never expected . . . but makes complete sense!
Godzilla battles the Megazord . . . and no matter who wins, the world will be at great peril from the combined threat of the Xilien invaders and Rita Repulsa! And if a giant robot and a giant monster weren't cataclysmic enough, how about Gigan-a cybernetic space monster ready to fight them both?
When Mars invades Earth, Godzilla surfaces from Tokyo Bay and is pulled into battle. Captured and taken by the Martians, Godzilla is forced to fight in a gladiatorial arena, where he faces his biggest challenge yet—KING GHIDORAH!
