One big problem with desolidification as a defense is that it prevents you from attacking or requires you to add the affects solid advantage to your attacks.   This would prevent you from dropping down and attacking.  
 
Another way to do this would be to buy gliding.  Since you can dive for twice your normal flight all you need to purchase is 30m of gliding to handle terminal velocity.  30m of flight with the limitations, gliding (-1), no noncombat (-1/4), and limited horizontal movement (-1/2) costs 11 points.  This would allow you to land in any hex directly bellow where you could jump to.  So, if you have a 4m jump you could land in any hex directly below a hex within 4m of where you start.  This also means you automatically land on your feat without having to make any kind of roll.   
 

I know better, bur I am stupid enough that I am going to do this anyway, so sit back, grab the popcorn, and watch the beating unfold. 
 
can anyone point out where in the rules being decapitated means you have to die?
 
remember that not only are hit locations optional, so, too, are the bleeding rules.  Even if you _are_ using the bleeding rules, there is quite a lot of leeway to decide what results in bleeding and what doesn't.  Assuming that you are, then when you take an amount of BODY that reduces you to negative, you bleed.
 
okay; fine.
 
if you take a headshot, you suffer a BODY multiplier to your damage.
 
okay; great.
 
Problematically, decapitation is _not_ a head wound.  We can argue that later, of course.  As written, it could be considered a torso wound, so figure your damage accordingly.
 
HERO doesn't do Location X has Y Hit Points, so we don't really have a method of determining just how much damage applied directly to the neck (which is not available on the hit location chart, but let's just say that it is a Called Shot with modifiers akin to a called ahot to the head) it takes to remove a head.
 
I am not completely certain, but I am willing to bet that it is less than enough Body damage to reduce the character to negative Body.
 
This is one of thise instances where the superhero / SFX are free thing really shows itself.  Because you can declare that your character is a robot or a cyborg or a sapient tree, you do not automatically fall over bleeding when someone lips off your anything.
 
We view it as a given because we know that people tend to much sooner without their heads attached than they do if the head remains in place.  Regardless of our biases, however, the rules don't actually make it mandatory.
 
That being said, strictly by RAW, there is absolutely no power construct required to remain alive after decapitation (speaking may be impaired a not, but that isnt mandated, either, I am,afraid). Nor is that, according to RAW, any way to actually decapitate someone short of completely pulverizing their torso (again, breathing may be impaired a bit, but it is still not mandatory).
 
Granted, releasing this bit of news to your players may result in lots of decapitated heroes fighting bravely on for decades, wearing their heads on a necklace like some gruesome pendant.
 
All that being said, I would think that the options for your build are, by raw, as simpke as declaring that decapitation doesn't kill them.  Granted, this will encourage some to run to the rules questions thread and ask for a new rule regarding decapitation, so I will go further and say this is as simple as making it a perk (possibly as part of a package).  Beyond that, consider the automaton power "does not bleed" and call it a day.
 
 
Now then, go ahead.  Feel free to beat me like I was the third monkey on Noah's Ark.
 

 
 
 
 

BINGO: We might look at a damage roll that slays a target (down to negative BOD equal to total BOD score) with a hit location in that region (be it head, torso or shoulder) and say "You have decapitated him - his body collapses as his head rolls down the hill", but all we have done is specify the special effect for the mechanic of "killed dead". Given we think of "decapitated" as "dead", perhaps we could require the character take some extra BOD, or defenses, or just "no hit locations; head only" with IPE, but that's just sugar-coating it.
 
Maybe we think it has in-game effects. 
 
Perhaps he needs "Striking appearance" triggered by a head hit (or some other mechanic) because the decapitated target continuing to function is terrifying.
 
Or maybe it's just "Distinctive Features" - that's certainly the kind of thing one notices, probably with an extreme reaction.
 
But if it has no in-game effect, it's just a special effect. Most characters don't have their heads fall off while they are still alive. So what?  Most characters don't have flourescent green hair, or a third eye in the middle of their forehead, or pointed ears. My character can have any or all of these things.  And it costs no points if it has no mechanical impact in-game.
 
If anything, having to cart your head around and point it in the right direction to see, rather than having it properly secured at the top of your torso, seems limiting rather than advantageous.
 
 
But this is a completely separate power.  Simply defining my character as having a removable head, having no head (Arnim Zola) or having multiple heads (a hydra) does not confer any special in-game benefit. It might be the special effect of an in-game benefit which is paid for as a separate mechanical ability.
 
Maybe that's "Regeneration, with resurrection adder, the special way to keep him dead is destroying the phylactery" with the Susceptibility of 3d6 BOD damage per segment if phylactery destroyed" - that does not mean he can take unlimited damage without being temporarily incapacitated, but the lich can have its body destroyed and be pretty useless until it gets a new one.
 

I think at worst a base should be treated exactly as a power a PC purchases which isn't apparently very useful. (Example: Transform skin color to Caucasian, only works on humans who are already Caucasian.) 
 
1) It isn't the GM's job to make the base useful in any way. Instead it is the player's job to make it useful if it is going to be useful. If the player can't figure out a way to make it useful, he'll spend his points differently on the next character.
 
2) It also definitely isn't the GM's job to treat the base as if it were a disadvantage that the PC took on his character sheet but had to pay points for instead of getting additional points for.
 
Now if the PC took disadvantages on the base, fine, those disadvantages exist. But having a base doesn't cause disadvantages to spontaneously appear out of nowhere if the PC isn't doing anything to create a disadvantage or purchase a disadvantage.

Yeah, like I stated earlier, there's a huge jump between "i dislike you because you look different/talk different etc" and "I dislike you because you are powerful enough to melt my brain"
 
Mutants aren't just odd looking or unusual.  They are actually, materially dangerous.  And they are going to supplant and replace non mutants according to Marvel Evolutionary Theory.  That's a huge difference from "I don't like you because you're from Nebraska".  That's an actual threat to my peoples' existence.
 
There's good reason and logical basis for fear of mutants in the Marvel universe, its not just mindless, content less, irrational hate.  Especially when you factor in all the thousands of times mutants actually have threatened huge bodies of people, if not the entire planet.
 
And at the same time, because almost no mutants look any different than anyone else, there's no reason why people should hate them and embrace other superheroes as happens constantly in the Marvel Universe.  In this context, there's no difference between Captain America and Dazzler: both have done great things and protected people, both are attractive and noble, both are consistently heroic (with a few mind control bad moments).  Cap is beloved and honored, Dazzler is hated.  For no other reason than "we want to push the anti mutant thing for plot reasons."
 
See, what I'm saying here is that no matter how much propaganda you put out, or what cool slogans you whipped up, people would not differentiate between mutant and non-mutant.  They'd fear and hate every superhero.

If you meant on my part, it was completely intentional.

From reading your OP, I gather that this fellow is like He-Man: Pulls out the Sword of Eternia, says "By The Power of Grayskull!" and transforms, keeping the sword around to use on his enemies. If that's the case, then here's my ideas:
 
1) First, build the power that transforms the PC into their HID with the Focus. Like so:
 
 
Activating this power turns Adam into He-Man, deactivating it changes He-Man back into Prince Adam.
 
DO NOT put this power in any frameworks that also have OIHID. In fact I'd recommend not putting it in any frameworks at all.
 
Any powers that can be used after the PC transforms should use Restrainable instead of Focus:
 
 
This power can be put in a framework.

When the T'Shol made their Invasion attempt, were they met by The Solution (I bet that would one time Ultra Woman kept her mouth shut )?

I think I know what he means.
 
Limitations affect powers, and should be priced based on how they affect the power they're applied to, generally without regard to other things the character can do.  For example, if Superman purchases a hang-glider (10" of Gliding, OAF bulky, big turn mode, lots of other restrictions), then he still gets the full value of the limitations on the Gliding power, even though he's got 50" of Flight x250 noncombat.  His Gliding isn't more expensive just because he's got a backup power that's just as good if not better.  He's paying points for both powers.  His limitations don't become less limiting overall just because he spent more points elsewhere.
 
If Captain Swordsman has 5 different magic swords, each with its own weird limitations (only affects evil creatures, only vs vampires, does not affect those blessed by a priest, only vs dragons, etc), it doesn't matter that he's got backup weapons.  Those limitations are still real.  He bought each of those weapons individually, and they all cost points.  He shouldn't be paying full price for 5 different swords.  That's way worse than just paying for one sword that does everything.
 
Now... there are certain circumstances where a character is obviously designed with powers that negate his limitations.  The Mind Mole has 10" of Tunneling through 10 Def material (with the ability to close the hole behind him), N-Ray Vision, and an Ego Attack.  His tactic is that he tunnels down into the ground, looks up at you through the Earth with N-Ray, and then brain-zaps you over and over again.  He has an OAF magic wand that lets him do this, and an OAF magic hat that gives him 30 points of Mental Defense.  Unless he runs into a very specific enemy build, his limitations will probably never come into play.  This is a situation in which the GM is justified in saying "I can't think of any way this limitation will ever come up, so for you it isn't worth any points".  Doctor Destroyer's powers all come through his armor, but because it can't be damaged and he never takes it off, he doesn't get any points back.

I see a few common threads emerging which I concur with, and steriaca touches on most of them here.
 
By default, the attack works on anyone the character targets and hits.  He can already choose not to attack some targets.  He is limiting viable targets, and that means there is a limitation.  Now we need to value it.
 
The question is how often he will target, or will wish he could target, someone or something that the KA will not work on,  That depends on exactly who it will, and will not, work on, which the player needs to detail.  Object, automatons, animals, entities that believe they are doing good/evil ("this is necessary for my people to survive"), entities that believe they are doing evil ("even if it meant I would starve, I should never have eaten an animal - truly I am irredeemably Evil").  It requires defining exactly what is, and is not, "evil" for this purpose.
 
Next, the GM has to assess how common that "evil" will be in his game.  That may be active ("I have ten years of games planned out, so based on that, your limitation is worth -1/2") or passive ("he took a -1 limitation, so I need to work in a lot of situations where there is a target he'd like to use the sword on, but it won't work").
 
In the course of this, we need to talk to the player - how do you envision this working?  How will your character use the sword?  Don't speculate - ASK the player.  "You don't plan on just randomly stabbing people to figure out who is evil, I hope."  If he does, maybe we need a discussion on campaign tone more than we need a discussion over differentiating a -1/4 and a -2 limitation.
 
Overall, the GM and the player need to get on the same page and understand the vision of this ability FIRST.  Then we can scope out how it interacts with the specific campaign SECOND.  Mechanical design is the THIRD step.
 
Many players, and even Hero posters, are used to games that will have "Weapon Property:  Only Works on Evil Things" already priced out on a list of other abilities.  In those games, the game designer has already set a campaign structure, so he knows how common "evil" will be.  The writeup of the property will (if done well) explain who it will, and will not, damage, and may even discuss the ramifications of random stabbings to determine alignment.  The game designer already has HIS vision for how this will work, so he will design the mechanics around that, and that is what you get. 
 
You wanted a different vision?
 
Welcome to Hero, my friend, where you get to design YOUR vision.  But that means you have to go through all of those steps above, because in Hero, YOU - the player and the GM - are the game designer.  Hero just gives you the tools to build your design, and realize your vision.

Given the "heals back" mandate of Transform, I don't see it becoming a years-long problem.  Socially, I don't see it-- _as suggested in the first post_ being too much of a serious problem, either:
 
OP Didn't say "turns them into someone else," but "swaps their genders."  Immediately springing to mind is the fact that I don't think anyone has failed to recognize Eric Idle as being Eric Idle even when in drag.  Yes; playing a woman, not being a woman, but still: as suggested, that's about the level of effect I understand:  Johnny!  You've gone and grown bewbies!  What happened, Mate?"
 
Going to something more close to the source of the inspiration:
 
The cast of Ranma 1/2 was freakin' _huge_!  Even for a cartoon, there was a shocking number of characters over the years.
 
Only _one_ of them failed to recognize Ranma as Ranma when he swapped genders.
 
In a world with super powers, green-and-purple skinned monsters, aliens, mole people, and lost lands of dinosaurs, the "well, my fingerprints are still mine; my DNA is still mine save that extra leg on the Y chromosome..."   In a world of stuff like this?   This is a straight-up joke power.
 
I have no idea what the nature of OP's campaign is, though, and that's the heart of the problem:  only OP does know.
 
 

Strangely enough, you don't actually have to be severely autistic to have difficulty with emotion.  Granted, it's a hallmark of autism, so we tend to go straight there for examples, but there are others both more severe (sociopathy and psychopathy) and far less (some Aspergers patients and an "on again, off again" diagnosis occasionally called "Literalism").  And it's not just emotion: a lot of these folks (autistics included) also have trouble with sarcasm, double-entendre, and even simple jokes.
 
It's actually frightening how much emphasis we put on the "humanity" of emotion when there are so many people collectively who have difficulty even _appreciating_ emotion, let alone understanding it.  The same goes with empathy: we talk about how it's a touchstone feature of being a living, sentient being-----   but there is an appreciable number of folks who simply aren't capable of it.  Stressing it as part of the "diagnosis" of being a "real human" becomes just a bit frightening....
 

 
 
Well great. I've gone and made myself sad...

This was too good not to share.  I found it at https://notalwaysright.com/they-might-be-coming-on-to-something/207328/
 
A bit of backstory for anyone reading old stories years from now: there’s a global health crisis going on, and a lot of people are acting like it’s either fake or no big deal. I’m waiting for an x-ray, and I overhear some medical workers talking.
 
Worker #1: “Did you hear that [disease] causes a loss of ability to orgasm?”
Worker #2: “No! Where did you hear that?”
Worker #1: “My girlfriend and I made it up, but if we spread that around, maybe people would actually care.”

In combat, I'd have you make 2 rolls: Roll-to-Hit, because the target very likely won't stand there and let you do the "Shave and a Haircut" gag. And a PS: Jedi Knight Roll (no minuses unless the target figures out what you doing and makes a DEX roll to avoid it (but if he's never seen you do it before, how would he know?)) because while it's cool, it's not worth a huge outlay of points for the effect, and a Jedi should have spent a few points for the PS if only to fake being a Jedi...
