There is a whole set up you can buy to play HERO in Roll20.  It is set up to roll the right dice and everything.  Let me see if I can find the announcement.
Check this out.
 
 

Instant Change isn;t targeting yourself, It's targeting the clothes you are wearing

You can use it to change costume, that's a Transform on your costume not on yourself.  Inanimate objects generally have 0 DCV unless they're being held by somebody who doesn't want you touching them. 
Changing your appearance is Shapeshifting, but if it's just "Nobody recognizes Clark Kent when he's in the Superman spandex", that's generally just part of the genre conceits and nobody has to pay for it. 

No, you don't. 

My rule of thumb is powers do not require an attack roll against an unresisting target.
 
It's only if the target is resisting your power that an attack roll may be required.

I'd buy it as Healing with a whopping bunch of Limitations (Extra Time for sure, and a Limited Power that the subject being Healed can't move or act for the duration). Regeneration's also a possibility.

Question: How do I simulate a person with the power to...
a) Force a person into a suspended animation state...
b ) ...and in that state, start slowly healing them.
 
The character can encase a willing person in black ice, and slowly heal there wounds while in this state. She needs not concentrate upon the power or anything. The ice will 'melt' once the person inside is healed, or until another condition she sets up happens.

Flying Dodge is discussed generally on HSMA 245-46. As noted there, a character gets one Full Move’s worth of movement when he uses Flying Dodge. If he’s already made a Half Move, then he only has a Half Move left to use with the Maneuver. See the HSMA discussion for other factors and information.
 
Regardless of how much movement a character uses with his Flying Dodge, he only gets to move once. He doesn’t keep getting to make a Full Move every time someone attacks him after the first attack that caused him to use Flying Dodge. He maintains the DCV bonus from the Maneuver until he gets to act again (just like with any Dodge-based Maneuver), but he doesn’t get to keep moving around.
 
If a character uses Flying Dodge and gets hit anyway, he still gets to use the movement he declared as part of the Maneuver. Getting hit doesn’t stop him from moving or cause him to lose any meters of movement.

Sorry it took so long for me to respond back to your answers, but I'd really like to say it really helped a lot. I understand it more and I'll try to create the base. I hope I can show you the base when I'm done, and you can give me some feedback if you're willing.

Well there ya go! If you can have a Dyson Sphere, you can certainly have one the size of a city. Also, there's nothing in the rules against having a city-sized base. Still, the cost...  wow!

If I remember correctly, 5th Ed Star Hero had an extended Base size/cost chart that allowed for Bases up to the size of a Dyson Sphere (a base that surrounds an entire star). 

Is this base for players or NPC?
 
If it is an NPC base then the answer is very easy - hand wave everything the players are unlikely to engage (especially non-combat stuff).  So say it is a super villain base (city) and there are security cameras everywhere constantly watching things.  You could build it as some kind of clairvoyance or you could just hand wave the answer.  If there are traps and/or minions then I would write them up.  But I wouldn't care about how much the base and followers cost for an NPC.  For instance a local leader of Viper is not going to have an underground city for a base.  To many resources tied up to one place - goes against good Viper doctrine.  But Dr. Destroyer would have such a base.
 
If it is a PC (or group of PCs), then I would work up a few of the items and then detail out the cost to the players in character or experience points.  Once the players realize they are going to be tying up a significant amount of the character's character or experience points.  Also I would make sure equipment fails on occasion (wear and tear) and those items require more XP to get it back up and running.  I would only do this for mega bases like the one you asked about.

Build the base you want.  The rest of the city is just "grounds."
 
Get awesome and buy the population as Followers.
 
 

or you could buy one base and then use the 5 point for 2x say 10 times for 50 points for the 1024 building base

Side point.  If it's a full-on city, I'd just buy the Universals from APG, applied generally to the city as a whole.  Universal JOAT...there's just about every kind of tradesman you want.  Universal Scholar. and Universal Scientist..the university as a whole.   

A full city would seem to imply a LOT more than just a base.
 
Putting a base underground is easy, that's in the rules.  The issue would tend to be cost;  what are we talking about here?  You say 'city' I start thinking in terms of multiple square miles...something like size 30.  I'm also hearing lots and lots and lots of people, which is tricky when you're talking a base.  
 
Be that as it may....just pay for things and do the actual layout as it's needed.  It's much like building any fantasy city;  you don't necessarily need to place every shop, every temple, every inn.  No one's gonna care. about 90% of it...just due to the sheer volume of detail.  Also:  in something as large and complex as a city, you'll tend to have multiple spots for *much* of the functionality...there's more than one lab for a PS:  Analytical Chemist, for example.    You might want to just create a broad district plan...this area's the University, this area's the major medical complex, this area's the admin center, and so forth.

Is the city really the full base? Or is there city parts beyond the base part?
Are there still people/machines in the base?
How is the bulk of the city secured against intruders/able to detect intruders?
What kind of setting are we talking about? Heroic? Superheroic?
 
In Stargate Atlantis, only the central tower of atlantis was really the "base". The rest of the city was as much setting background, antagonist and adventure location. Not really fully controled by the earth-humans.

The skills are generally only available in the listed area specified in the Base. I.e, you can’t use Breakfall every where, just in in gym. Now as to the Underground city being a Base. I don’t see why not. You’re just having the “rooms” be connected by “open” space. 
 
Good question though ought and My answer is nowhere official nor RAW.

This is going to very by taste.  I think there is a cost to the size of the base but everything else is about what the base can provide.  I think if you are concerned with detail then it would make sense for there to be some time limits if switching between resources, perhaps a variable time effect that is random to reflect that in a base that size you are not always where you need to be to access the necessary resource. If you are consumed with detail then you would indeed map it out and do the detail.
 
Personally I would have a fixed time delay to access any resource and handwave the rest.

4. I was gonna run it as a Heroic Campaign 275CP
 
I'll try to build some of the characters "I'm going to change the campaign to be more like "A Certain Magical Index" instead, but it's still kinda like My Hero Academia

Hey, I was wondering if I can get some tips and tricks on how to be a GM for heroes. They aren't any games being run where I am, and I've never actually played the game before, but since there's isn't any games around me I wanted to run a game myself. I have some hero's books and I have a general idea on how to make characters, still figuring some things out. 
 
My Idea for a campaign would be like My Hero Academia the anime, but I'm not sure how to go about it.
