If SpaceGodzilla was in DAM

Without space godzilla's crystals I do not see him putting up much of a fight at all. If he doesnt have crystals easy defeat, with crystals easy victory.

I see. If he did, how would any of you think how this fight would go down?

SpaceG would be clobbered just as bad as Ghidorah was, with or without crystals. In fact, it could be even worse, since, being based on Heisei Godzilla, SpaceG is an extremely poor physical fighter, whereas Showa monsters excel in tooth and claw combat, and he, unlike Ghidorah, has no quick and reliable way of flying away (he has to either slowly levitate or change into a different form to fly). His Corona Beam would do some real damage, no doubt, and he could keep away one monster at a time with telekinesis, but these abilities would not save him.

^Too true. If Godzilla and MOGUERA eventually took him down, 10 monsters would be no issue.SpaceGodzilla's physical abilities are abysmal. We never even saw the thing take a single step in the entire movie he's in. He just stands around zapping things. Such a boring adversary. Watching 10 monsters with the ability to move take him out would be gratifying.

Would 10 monsters actually fight him or would it be like Ghidorah where only 3 monsters do the fighting while the others stand and watch.

If it's like Ghidorah and the same monsters are fighting him, Gorosaurus, Anguirus, and Godzilla, SpaceGodzilla would annihilate them. Neither Gorosaurus or anguirus have any way of getting close to him besides running at him and we saw how well that works in vs SpaceGodzilla with him simply throwing them away. The reason that he was beaten was because his shoulder crystals were destroyed and none of the monsters that took part in DAM besides godzilla have any way to destroy them. The heisei monsters while being worse hand to hand fighters with the exception of a few make up for it in sheer power and size.

What showa monster is going to make it through a barrage of giant crystals coming at them besides Godzilla? What showa monster has a way to destroy his crystals? Showa monsters are hand to hand fighters and that doesnt go well against long range flying monsters with shields and telekenesis. Unless all the monsters took part I don't see the showa versions doing well in this matchup. 

I think you, like many others, exaggerate Spacegodzilla's power. IIRC, he was never shown levitating more than one monster at once, and he only used his crystals as missiles once. If he tried to send a constant barrage of crystals to hold the monsters back, he would run out pretty fast, and then he'd have to either try to make more while being pummeled, or just fight without them.

I suppose if it were just those three monsters actually fighting him, he might have a chance if he can keep them all away long enough to take them out with Corona Beams, but it would be a tough fight. And then, of course, it's unlikely the other 7 would continue to do nothing afterwards.

Of course, there's no denying that SpaceG, even at his most overpowered, would be just about screwed if all 10 monsters ganged up on him. It wouldn't matter if he could use his Corona Beam, telekinesis, and crystal missiles all at once, there's no way he could keep them all away from him.

It's not as though Space Godzilla is physically weak. He threw MOGUERA with his tail a decent distance, he exchanged blows with Godzilla and when he hit him energy came out making his attacks more deadly. The one time he used the crystals it was a pretty steady stream of them and Godzilla had to destroy a few with his ray before they hit him, something almost no showa monster has the ability to do, thus most have to take the hits. He takes numerous shots from the plasma from his eyes and the cannon on his abdomen, godzilla's beam, and the spiral missiles with almost no damage. What showa monster could match that level of power? None, they're all physical and while that may be effective for their generation there's no way anguirus's teeth, or Gorosaurus's kick could do more damage than plasma. He could always just fly and then the only monsters that can do anything are Rodan and Varan, who don't really measure up with a monster that flew threw the astroid belt while beating MOGUERA. I mean look at what the 3 main monsters he'd fight would offer individually

Anguirus- The punching bag of the Godzilla universe. Aguirus basically is the monster that always gets wrecked to show how powerful the foe is before Godzilla takes him on. He get's destroyed by mechagodzilla without mechaG even using weapons. When he tries to solo ghidorah he get dropped from the air then stepped on till he collapses, and in Gigan he ran headfirst into a running saw. Anguirus is tough to offensively he's probably one of the weakest monsters

Gorosaurus- Can't say much as he only appearas in DAM and King Kong Escapes so maybe he's badass and no one knows but judging by the fact Ghidorah ignored him allowing him to get behind him and Kangaroo kick him, essenially the only thing he brought to the fight I wouldn't put my money on him being a heavy contender for on the list of strongest kaiju

Godzilla- The only one of the three that can last, granted space Godzilla is made from a bigger godzilla and is much larger that him but showa Godzilla's very tenacious so at least he has that going for him.

So if it was like DAM I would put my money on Space Godzilla over those 3, but if every monster in the movie attacked of course he'd get destroyed just like every monster from the series would.
