My brother read ROM and I'd read it as well.
It wasn't until years later that I really, really got to like it more.
Underrated Sal Buscema art and story by Bill (Micronauts) Mantlo.
Rom has kind of a cult following, deservedly so. A really good, mostly self-contained series.
Marvel had him interact with quite a few Marvel characters, including
Torpedo, Henry Gyrich, Forge, Nightcrawler, Colossus, Captain America, Wolverine, Galactus, Sasquatch, Namor, Dr Strange, Rogue, Gremlin, Snowbird, Quasimodo, Shaman, Kitty Pryde, Vision, Storm, Ursa Major, Vanguard, Marrina, Darkstar, Moondragon, Gargoyle, Valkyrie, Seaweed Man, Sir Denis Nayland Smith, Destiny, Pyro, Avalanche, Black Jack Tarr, Nick Fury, Blob, Leiko Wu, Mole Man, Mr Fantastic, Human Torch, Tigra, Thing, Angel, Terrax, Ant-Man, War Machine, Clive Reston, Professor, Hawkeye, Mystique, Scarlet Witch, Wonder Man, Iceman, Beast, Spider-Man, Shang-Chi, Arabian Knight, Captain Britain, Starfox, House of Shadows, Space Phantom, Jack of Hearts, Digger, Living Tribunal, Beta Ray Bill, Landslide, Devastator, Xandarian Worldmind, Awesome Android, Powerhouse, Comet, American Eagle, Dum Dum Dugan, Black Knight, Kala, Hercules, Mockingbird, Daredevil, Parnival Plunder, Thor, Hulk, Invisible Woman, Diamondhead, Mad Thinker, Adora, Nova, Thinker, Ego, Jarvis, Moon Knight, Iron Fist, J. Jonah Jameson, Captain Marvel, Cyclops, Iron Man, Protector, Tanak Valt, Luke Cage, Metal Master, Peregrine, Shamrock, Missing Link, In-Betweener, Spectrum, and the Beyonder.
You probably already know, but IDW has Rom now is has integrated the character into their Revolution (Hasbro) universe.
Haven't read it yet, but I will later when it goes on sale.
