It's not really any of these that is a deal braker for me. Yes, the name "Shimmer" is not from mythology, but is a lot like "Tremor".I mean, yes, she does shimmer. But I sincerely doubt they would name this character 'Shimmer', when other divine beings have had names drawn from world mythologies.
'She shimmers, so her name is Shimmer' is a weird justification. Raiden crackles with lightning, but his name is not Crackle.
While we're at it, let's look at the other two original characters this person claims are in the game, besides the Dream Realm woman and Kano's son (characters almost everyone is expecting in MK11):
"Mercia is a new female Witch and resides on the moon in Earthrealm. During the Sindel Masacre, Mercia saves Johnny and Sonya from death as she saw Cassie playing a role in saving the realms. She also secretly imbued Cassie as an Embryo with the green magic that stopped Shinnok."
She lives on the moon? A cute nod to the silhouette of a witch in the old Pit stage, I guess, but that seems unlikely. More to the point, this doesn't bear any resemblance to the actual lore: Cassie's 'green magic' is established in MKX to be something passed down through the Cage bloodline, as they are descended from a cult of warriors in the Mediterranean that bred empowered warriors for the Elder Gods.
"Ruin is a male from Nightmare Realm (first ever appearance in a MK game), whose parents were murdered by Dark Raiden. He joins the fight against Earthrealm and wishes to show Earthrealm what a nightmare truly is. We learn that the Nightmare realm is where dreams, hopes, and ideas went to die. Unrealized dreams are sent there and are twisted by it’s dark energies."
This one's clearly just somebody's DeviantArt OC.
The fact that there is already a semi-established canon that the Cages powers come from an ancient Mediteranean cult that bread warriors is not enough for NRS not to change it. They're quite known for changing or forgetting their own lore. The guy who wrote the leak seemed pretty savvy about Mortal Kombat, so saying that Cassie got her powers from another place than her dad is a really bold move, as every tiny MK fan who played MKX knows it was the same kind of power as Johnny's. And Ed Boon twitted that witch with the moon in the background pic a few weeks ago, what was up with that?
But what really makes it non-believable is that it did not mention the Custom Variations. 5 DLCs instead of 6 I can accept, considering that the Italians might be counting Shao Kahn too. But no mention of the Custom Variation?
It just says: "Gear will also have no effect on vs. gameplay and will only be cosmetic. During story, gear will change your stats. Skins will also be present in the game, which will be unlockable through doing specific tasks. For example, you can unlock MK1 Scorpion by winning 100 online matches with Scorpion. Each character has 2 unlockable skins, in addition to the base skin/gear loadout."
This would have made sense after the original MK1 Scorpion in the trailer, but not with the announcement that there will be infinite possibilities to customize the characters.
None of the leaks gave that. So either they were all wrong (though that initial one seemed very, very believable and I still think that guy was James Fink though he tried to deny it later, he had his whole artitute with the "now get off my case about it" line like a friend was pressuring him into revealing what he knew about Mortal Komvat 11).
This or.....NRS is really trying to avoid revealing that one of the leaks was in fact true and they're throwing us off course with things like "time-bending story" or "custom variations" when, in fact, these are just exaggerations.
