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? Written by superstar scribe Cullen Bunn (Godzilla: Cataclysm) and illustrated by artist extraordinaire Freddie Williams II (Batman/TMNT)!
