It is not very described, her power is "cannot lose", which is very ambiguous. Summoner says that it was precisely that power by which she betrayed Arakko but Summoner is a liar.
Assuming he is telling the truth in this, her power would force her to be a traitor on whatever side she predicts it will lose, indeed. Like I said, it looks like a Domino-like power but being a jerk.
All-Black the first symbiote was created to kill Celestials who are immortal energy inside armour somewhat similar to Rockslide though Celestials are much more powerful so it isn't unreasonable that a symbiote Necrosword while weaker than All-Black could be enough to kill Rockslide.
Pogg Ur Pogg is the best
some of the Krakoa team has to lose. still think Cypher is one of them. I just can't buy him as a fighter winning vs these guys.
Maybe blue husband has the Leech-like power to suppress another person's mutation and was able to turn War from a living flame to a flesh and blood woman, for a time, and they had nookie (and through the magic of mutation, her pregnancy wasn't interrupted by her turning into living flame from time to time, just like mutants who can mist or intangible or shrink or whatever don't lose the contents (or explode and die) of their stomachs/bladders/inner ears/intestines/etc. every time they transform).
Or maybe he's got the power to mimic another mutant's mutation, turned himself into living flame, and they burned into one for a time, and a few months later, she spat out some coals that coalesced into a humanoid baby?
Or she could always transform back and forth, like Colossus or Emma, but, life being super-dangerous and surrounded by might-makes-right supremacists 24/7, she generally prefers to stay in a form that can't get poisoned or backstabbed or death-stared.
**** be weird. Is what I'm sayin.'
Yeah, Doug's gonna get paired up with the 'Silent Commander' and be all like, "C'mon man, say something so I can use my mutant power!" And then remember that, attached to his arm, is Warlock, a Technarch royal whose dad was powerful enough *to rip a star in half and throw it at him* in his first appearance, and punk Silent Commander like the event fodder warm-up band he is. ('Cause we all know Mrs. A is the main dish and the chillun' are just finger food to whet the appetite.)
Meanwhile Gorgon and Death are gonna have a staredown, see whose deadly gaze kills the other the fastest...
Brian Braddock is gonna look up and up and up at Pogg Ur-Pogg and be all, "Seriously? I'm not even a mutant. Can we shuffle the deck and try again?"
I'm sorry but the whole mutant power to win thing is stupid. At least when it comes to Domino with her mutant power of luck it's all about effecting your surroundings for things to happen in your favor. With Isca power it just tells her who wins
Seems pretty similar to Domino's to me except more potent. Someone described it as low level reality warping focused around her survivability. I mean her ability is powerful enough to force her to switch sides in the middle of a conflict because she can't be on the losing side.
White Sword seems to be more like a cross between Apocalypse/Elixir. He's far more stronger than Elixir when it comes to healing and resurrecting the dead.
