Chris Goodwin posted what I was thinking, its damage negation / damage reduction with an activation roll.  If you really want it to be based on the player's roll, then you can add that as a side effect: does not work if attacker makes DEX roll, -1 DC of DN per x points DEX roll made by.
 
I have to add though; I cannot puzzle out exactly what the DEX roll is meant to simulate.  Is this supposed to be some Gun Fu move where you do Kung Fu as you shoot?  How does being particularly agile result in a reduction of the UFO's protection?

You could handwave it.  But that seems unsatisfying and not what you're looking for.  So let's look at it a little more closely.
 
"...attack will be decreased by 15 Active Points..." sounds like Damage Negation for 3 Damage Classes.  "Slick Hull" also sounds like the perfect SFX for the Damage Negation Power.
 
"...per point the DEX Roll is failed by..." sounds like Requires A Roll (RAR), with some slight modifications. 
 
From a mathematical standpoint, the power user's roll to activate is the same as the target's (or in the case of a defense power, the attacker's) roll to avoid.  This definitely has "must be made each Phase or use" modifier (-1/2 more Limitation) for -1 total.  "Uses Characteristic Roll" doesn't modify the value.  Normally there would be an Active Point penalty to the user of the power, which can translate to an Active Point bonus to the attacker.  We can reduce the initial value of the RAR Limitation to compensate, to -1/2.

In this case, the user of the power (the UFO) gets some effect on a failed roll (or, a successful roll by the attacker).  How to handle this?  Multiple buys of Damage Negation, with increasing difficulty. 
 
Essentially, you're buying 3 DC worth of Damage Negation, with "Only If Attacker Fails DEX Roll", another 3 DC with "Only If Attacker Fails DEX Roll by more than 1", another 3 DC with "Only If Attacker Fails DEX Roll by more than 2", and so on. 
 
I'd put the value of the Limitation for the initial buy at -1/2, per Requires A Roll, and probably -1/4 per additional reduction.  Make sure to factor the previous Limitation values in, so -1/2 for the first, -3/4 for the second, -1 for the third, and so on. 
 
Allowing Extra Time to grant bonuses is already handled in the Skill Use rules; I'd use the current rules rather than the ones given in the original writeup.
 

It's a Danger International adventure. The one that was produced.

It's almost complete. I just got a shipment today of nearly all of the books I didn't have. And I just ordered today the final book that I didn't yet own. It should be here in a week or so.
 
Horror Hero
Hudson City Blues
S.H.A.D.O.W. Over Scotland
Watchers Of The Dragon
 
I got those today. The next one coming is Justice, Not Law

I usually have done it as simply a limitation, "For Stunning Only, Target Takes no Actual STUN Damage, -1/2".

If you want a character to just appear to be different things, like the octopus, its just flat out shapeshift, use touch for how its shaped (and thus appears to be formed as) and sight for the colors and believable in pattern etc.
 
Stretching allows a character to "ooze" through smaller openings, basically you can fit through any opening the size you can make yourself small enough to fit through:
 
 
So basically you can fit through small openings by stretching to be longer, for example.  It takes 5 points to be able to do this, each 5 points a doubling you can stretch to. 
 
Shapeshifting allows you to shrink or grow your form slightly, so you might be able to use that to fit through something slightly smaller using that. 
 
Desolidification would work to allow you to fit through anything, stack on some limitations like how it doesn't protect from damage and cannot pass through solid objects and it works.

Bought the book. I recommend buying it here rather than DriveThruRPG as they only have the PDF for $15, and not the package deal offered in the Hero store.
 
There are 21 Heroic characters broke out (by my count) in the following way, in order of point totals but not how they appear in the book:
1 built on 100 + 40 Complications
1 built on 175 + 50 Complications
1 built on 175 + 50 Complications (+20 xps)
1 built on 225 + 75 Complications
1 built on 225 + 80 Complications
12 built on 275 + 100 Complications
1 built on 275 + 100 Complications (+85 xps)
1 built on 275 + 100 Complications (+250 xps)
1 built on 275 + 100 Complications (+280 xps)
1 built on 275 + 100 Complications (+525 xps)
 
I'm still going through the builds, but they cover quite a range of types and abilities.
 
Despite the low point total, the first character, The Muffin Man, is quite a vicious piece of work.
 
The top-pointed one seems suitable for espionage drama, although more like a Mission Impossible movie villain than a James Bond one.

There is a maneuver called Cover which seems to be what you're looking for.  It's on 6e2 p. 85.

Good, bad, or indifferent, its meant to simulate martial arts.  Which are different than just grappling or brawling.  Grabbing something and throwing it is not the same as how martial arts works.  The rules seem to indicate that you get the same results and it acts the same, but aren't very explicit or clear about it.
 
As for the argument that martial artists are not typically gigantically strong, sure.  But they also balance on leaves, run up walls, etc in movies and other source material.  Its just not part of the genre to legsweep someone and send them flying for meters.

From a comic book perspective, that's how characters like The Confessor, Spider-Man, Batman, Daredevil, The Question etc all were written: they handle this stuff.  From a Champions campaign perspective, I have long wanted to run a police campaign with very low-end heroes as cops on a special squad (like Alphacore, but they're more powerful).  You can do regular police stuff, special situations like SWAT engagements, and low end superheroes as well as mobsters, etc.

I'm sure Bats would do just fine against Spidey's foes, but it also depends on who's writing him. 

One thing I do have to say though is that characters that start out as low powered end up much more powerful than ones that start out as high powered. I am pretty sure this is because they are spending points on their character based on what has happened and not just guessing what they want.

We are taking that as the given by which "challenge" is to be judged (or so I assumed; this one could be entirely on me).
 
Given a teen with super-strength, super agility, damger sense, ranged restraints,  etc--
 
I find it difficult to accept that a 40-year-old normal human who fights bare-handed in a rejected disco costume presents a serious challenge to said bug-eyed teen.
 
 
 
 

Spidey’s rogues gallery started with low-pointed builds but most of them have been saving up their XPs over the years.
 
If you treated Spider-Man’s career as a solo Champions campaign, or maybe one where other players play the various villains and occasional team-up heroes, the internal clock in that campaign has been ticking away around 10+ years, and the external clock for several decades more. That represents a lot of table time, so even a stingy GM would have given Peter’s player (and those who keep reoccurring in his rogues gallery) hundreds of xps by now.

That version of Adrian Toomes got a considerable tech upgrade for the movie. The original comic character was much more basic, although his equipment did improve over the decades.
 

 
 
Doc Ock's body is supposed to be only human. First punch to the chin by Spidey should have taken him out. Although it's not mentioned anywhere that I'm aware of, I always assumed there was some kind of feedback from his artificial arms that strengthened his body. That was the gimmick applied to the antigrav wing-suit worn by Vulture above.
 
 
The were called the Enforcers, muscle and killers for hire. Original members were Ox (very big and very strong), Montana (expert with a lariat), and Fancy Dan (skilled HTH fighter and acrobat, shortest of the three but hardly a "dwarf"). Again, just human, but each exceptional in their way, and worked well as a team.
 
 
So you're okay with a kid in a red and blue webbed leotard and a bug-eyed mask fighting crime, but draw the line at a "deadliest game" hunter in an animal-themed costume?

Out of all the Dark Champions books, this one has gotta be my favorite. I thought the villains especially had interesting themes and unique write-ups, including their gadgets, what their henchmen dress like, and the types of crimes they commit. Really hope we can see a revival of this one day.
 

Wikipedia claims Sue Storm started using force fields in FF issue #22 (January 1964), but it's Wikipedia, so best to wait for confirmation from another source.

In the early comics all the super heroes fought against fairly weak foes.  A lot of the early supervillains used gadgets instead of having superpowers.  They also tended to be one trick ponies.  

As LL says, read the early stories.  He has trouble with enemies including:
 
 - an old man with a flying suit;
 - a pudgy scientist with robotic arms;
 - a cowboy, a bulky thug and a midget who knows martial arts.
 
Just off the top.
 
If you write Spidey more powerful, some enemies can be scaled up, but others don't make as much sense scaled up to match SuperSpidey.

I agree. At the start of his career, Spidey had trouble fighting opponents who were really just exceptional humans, e.g. the Enforcers, Mysterio, the Kingpin, Man-Mountain Marko.

Stretching is a power set I haven't done a lot with other than "this creature has tentacles" but it can be interesting if done well.

The party consists of three characters, each built as Powerful Heroes (225 points and 50 Complication points).
 
1) US Marshall Daniel Doyle (character image is Clint Eastwood from one of his early westerns): A revenant that keeps this a secret and is dedicated to hunting evil. Talented with a gun and durable.
2) Sergio Cortez: (character image is Antonio Banderas from the Mariachi movie): A bounty hunter of both men and monsters. A thrillseeking womanizer who is in this for the money. A prototype of Zorro without a secret ID who is very handy with a sword and very stealthy.
3) Samuel Smith (character image is Bruce Campbell from The Adventures of Briscoe County, Jr): A cowboy with immense gun skills who is a weirdness magnet rather than an actual hunter.
 
Two of the characters are armed with cap and ball handguns except for Marshall Doyle, who is armed with one of the earliest brass cartridge weapons available as of 1855 (a French-made Lefaucheux M1854).
 
In the first session, Doyle and Cortez are tracking something heading west, which they think is a werewolf. They discover that both a small nest of vampires and at least one werewolf are in Fort Yuma. During the session, Sam is bitten once by a vampire and later by a werewolf, injured but not badly so.

After some delays due to holidays, illnesses and personal business, we had another session of the campaign.
 
Sam achieved the trifecta by getting bitten by a zombie, in addition to his previous bites by a vampire and werewolf. The trio intercepted a message to ‘Lord Black’ and ended up accepting a bounty from him when he confronted them the next morning. He had some Pinkerton goons with him at the time, and he was quite put out because someone burned down the eucalyptus trees he was growing to provide railroad ties for his planned railroad from Texas to California.
 
Most of the session was spent dealing with Bella Rosa, a headless witch with a sizable collection of severed heads she can use as her own. Her favorites were kept in a closet in her room.
 
The womanizing Cortez gets quite willingly seduced by her, and he ends up increasingly enthralled by her witchcraft. Doyle and Sam tried to figure out what to do about the creepy but beautiful witch and Doyle ended up using a quantity of dynamite to blow up her hacienda, and himself. Fortunately, he is a revenant and will eventually recover his missing BOD and regrow his lost body parts.
 
It is uncertain if the witch survived, but there was no body found in the ruins.

You know what makes Aquaman cool?  Um... nothing.  I like the character Jason Mamoa plays, but he's not Aquaman and he's not a superhero.  He's just a dudebro with powers.  Namor is a lot more interesting because he's such an arrogant jackass.  You can make an interesting water guy but not Aquaman.
