Honestly with a name like Cataclysm The Ultimates Last Stand it doesn’t leave much to the imagination . For many the Ultimate Marvel Universe is coming to an end. I don’t think it’s happening but I do believe that it will means several things.
1.The end of the Ultimates as we know it. I think the name says it all. It will be the Ultimates last battle. The current roster of Ultimate Captain America, Hawkeye, and the rest (it may include the Dark Ultimates) in a battle with Galactus.
2. Like Ultimatum was a hiatus to the mutants, this will be the same for the Ultimates.
3. A Ultimate Marvel NOW like relaunch. I see it as a strong possibility. A new team of Ultimates (like MC2 version).
AND bedside…..joining Ultimate Marvel with 616 (regular) universe is stupid just to save Miles Morales. I seriously doubt that MARVEL will kill Miles Morales. He’s an original Ultimate creation. So you are telling me that you will transport Miles into the regular marvel and screw his family, friends and network? SERIOUSLY? I doubt it, but this event will means changes to Ultimate Marvel. Time will tell.
