Are there multiple Vice-Versas? Canonically, it's orange, but Cerebella's ending shows her wearing a white one.
It's seen in multiple colors in gameplay, so I wouldn't be surprised if Vice-Versa could change colors at Cerebella's will.
Multiple Vice-Versas doesn't sound unbelieveable. But one would assume nobody else would be able to use the "alternate" Vice-Versas either.
It's outright stated the Cerebella is the only one capable of controlling Vice-Versa, which is why Vitale even bothers keeping her around. This likely Josses the "multiple Vice-Versas", or at least means only one can be "activated" by Cerebella at a time.
I always thought Viceversa was painted white to fit in the Play Boy Bunny motif.
Vice-Versa can grow sunglasses, I don't think changing colors is that implausible.
If Samson's mouth is on the back of Filia's head, what happened to Filia's brain?
Samson is just a shapeshifting mass; the mouth doesn't go anywhere. Filia's brain is probably fine.
I thought Samson could've eaten all of Filia's internal organs and Filia's entire body was already filled with his shapeshifting goo. I mean, it's a good source of bones for her Level 3 super...
An additional notes section on Filia, alongside noting her babycheeks and chubby body, notes that Samsom's mouth is like a portal. This would indicate that Samsom's entire body exists inside Filia, meaning that they co-exist, in a kind of shapeshifting phase. So, when Filia is moving around, or doing one of the few attacks she can do without Samsom's help (her Low Kick, for example) then her body is the dominant, and thus Samsom exists only as a portal; when the majority of Samsom's attacks occur, then Samsom is the dominant and Filia is just a vaguely-conscious husk of flesh.
Just how the hell is Parasoul's wish impure? Her only goal is to protect the innocent people, and she has literally no selfish gain from the wish whatsoever.
Parasoul's wish might have been seen as impure because it was only a wish to protect her sister, the one person most important to her, without much thought to anyone else. It was selfless, but maybe not selfless enough for the Skull Heart? She may also be non-pure hearted. Or, since the wish disqualified Umbrella from being the Skullgirl, it could have needed to shuck off the burden onto a different host.
I assumed it was because the Skull Heart is a colossal dick and is deliberately trying to find reasons to declare wishes impure.
See also: declaring Filia's wish as ever-so-slightly impure, because Filia, in her amnesiac state, thinks she harmed Painwheel in her past. Her guilt isn't even real.
As a Jerkass Genie, the Skull Heart would certainly not be above taking advantage of the Exact Words. And those exact words are "...if she is impure of heart..." Meaning that while Parasoul's wish was totally selfless and pure, if the Skull Heart looked deep inside Parasoul and found even the tiniest trace of impurity—like, I dunno, a memory of shoplifting a candy bar once when she was a kid or something—then it could go "Aha! Your heart isn't pure because you haven't been 100% completely good all your life! That means I can turn you into a Skullgirl, mwahaha!"
Umbrella might have been the primary beneficiary of the wish, but Parasoul had her own selfish reasons for not wanting Umbrella to die: she didn't want to lose her. It's like if someone wishes a loved one back to life. The loved one might be the one profiting directly, but they're only being brought back because the wisher can't let them go or move on.
Maybe they can produce infertile offspring, like horses and donkeys can?
So Squigly's mother became the Skullgirl 14 years before the story. Given that Squigly rose in response to the Skullheart before and rises in response to Marie becoming the Skullgirl, and Parasoul's mother being the previous one....what happened with Squigly during THAT Skullgirl's rise?
Nothing. Word of God has confirmed that Parasoul's mother was in another country when she went Skullgirl, and Skullgirl zombie-making powers don't extend that far back.
It seems like the Skullheart's been around a while — though not, as Leviathan says, forever. Still, why hasn't the Canopy Kingdom started practicing cremation of the dead (like the Free Folk of A Song of Ice and Fire do to keep their own dead from rising as wights) to keep the undead legions the Skullgirls can raise down to a minimum?
It's possible it might not do any good. A lot of the minions the Skullgirl summons are almost totally skeletal in nature, and while cremation takes care of bone, Marie's shown some modicum of regeneration from nigh-obliteration. It's possible this transfers down to the Skullgirl's minions.
The coffins in the Rooftops Assault stage are shown covered in chains, which may have held in previous generations. Marie being able to uproot graves and entire buildings likely overpowered them.
Skullgirls are said to appear every seven years. So Squigly's mom was the one 14 years ago, then Parasoul's mom 7 years ago, then Marie now. Still, it's as if she somehow did nothing during the time of Parasoul's mom as a Skullgirl.
The Queen had to threaten all 3 kingdoms so had to cross some borders. Squigly may have just been out of range and stayed dead.
If you know that you're going to become a Skullgirl eventually (as certain characters do in their endings) and you want to make sure the world isn't terrorized by your Skullgirl self in the future, what's to stop you from committing suicide? Can the Skull Heart stop you?
