If Marvel had ever done a What If issue for ROM I think it would have been over the final showdown for Earth in issue 65.
And who knows maybe the cover would have looked something like this photoshop hatchet job I did tonight. For a very comprehensive and funny recap of ROM 65 "The Final Conflict" go to:
Of course there are a lot of other What If themes from the ROM anthology that would have been interesting to see ( What If Brandy Clark had never become Starshine or What If FireFall had become Greatest of the Spaceknights ) but with out a doubt the events in issue 65 had the biggest impact on the mainstream Marvel Universe.
So if the Wraiths had gotten the drop on ROM and put him down, would Earth's heroes have been able to the task of thwarting the Wraith's "World Merge" apocalypse plan? A plan that would have brought Wraith World and it's black sun into Earth's orbit causing horrific environmental damage that would make BP & Exxon look like green energy companies. And don't forget, back in ROM # 27 Galactus ( "The big G" ) tried and failed to devour Wraithworld and it's sun and received an ass pounding as a result that would have made a stay in federal prison look like a trip to Disneyland. As always, if you have any thoughts on other ROM "What If" scenarios or on my cover concept please do share them.
