I don't remember why ROM ended, if it was at the behest of Hasbro or not. But it's definately why they can't use him today, because they don't own the rights. I did find this on Wiki, which I though was interesting. I'll have to check some of my back issues. As Marvel Comics no longer possesses the licensing rights to Rom, the character may not appear in his armored form. However, Marvel has found ways to work around this dilemma. During the wedding of Rick Jones to Marlo Chandler, Rom and Brandy returned to Earth as guests at the ceremony, and Rom greeted the Hulk with a friendly handshake. In the recent Captain Marvel series featuring Genis-Vell, Rick Jones was shown to own a toaster in the shape of Rom's helmet. In the alternate world of Earth X, Rom had ironically been banished to Limbo and was battling against the very Dire Wraiths he had sent there. Rom was seen in human form wielding his Neutralizer and using his chest-plate as a shield. He was referred to only as a "spaceknight." In 2006, Marvel reprinted the Official Handbook of the Marvel Universe as part of their Essentials line of trade paperbacks, including the Rom entries. In the South Park trilogy Imaginationland, which featured characters based on many pre 1990s television and cartoon sources, an unnamed background character heavily based on Rom (by it's appearance) can be seen several times wielding a sword.
