ROM: The Complete Marvel Years Omnibus, Volume 1 (ROM #1-29, Power Man and Iron Fist #73)

He strikes from outer space... and nothing can stop him! Marvel Comics is proud to present the iconic early adventures of the greatest of Spaceknights - Rom! Centuries ago, Rom pledged his life to protect his planet, Galador, from the evil Dire Wraiths. Now, Rom has tracked these vile creatures across the cosmos to Earth, where they have infiltrated the highest levels of power - including S.H.I.E.L.D. itself! Armed with his energy analyzer, only Rom can see the Wraiths' true form - and with his neutralizer, he can blast them into Limbo! But what will Earth make of this armored invader? Will Rom's quest be aided or hindered by encounters with the X-Men, the Fantastic Four, Jack of Hearts, Nova, and Power Man and Iron Fist? And when Galactus targets Galador, can Rom and his fellow Spaceknights save their homeworld from destruction?
