Sanctaphrax
I thoght about it... But the concept of character is about action, and I focused on the verstality more than pure effect.
Anyway, new concept:

The guy already has a silly skill total. I would be reluctant to add to it any further. The good news is that you don't have to add to it. If you use stunts intelligently, you can cover his competencies pretty well.

I'm honestly a bit confused, though. You had an earlier thread where you asked for advice on how to build this kind of character, and I sketched out one way to do it. You seemed to like my approach, but here you've gone on a completely different track where you spend more and get less.

That aside, I think people are overrating the Undersiders. At the beginning of the story I doubt any of them were even Submerged, and with a decent FP supply Flayer could probably take out any of them. High-FP mortals don't really exist in Worm canon, but that's beside the point.

I got your point, but I still don't think, that Flayer with his friends' help can't be the gung leader. I mean, Kayzer and Lung are not Thinkers, but they ruled their gungs during the long time. Yep, they were capes, but Kayzer wasn't the strongest capes in E88. So, if Flayer will be clever and skilled enough (now he had 70 skillpoints) and his mates will be ready to listen him (cuz he actually most clever of them) - why not? He at least as much as smart as  Grue or Skitter, and now Wendigo and Hummersmith are quite strong, no? And Serpent and Jusper will be stronger too.
P.C. What you think about the backstories of Wendigo and Hummersmith?

I'm still don't finish, but I'll consider what you say.
What if I give him also Great Intimidation, Good Rapport, Great Presence and Average Perfomances?

Actually, they must be on the respect-level of Undercovers. I mean, they can't destroy E88 or ABB, but they must be strong enogh to keep their district.
About tons of superpower - Wendigo is quite strong and I want to "lift" others to his level. Flayer will be brain, cuz he clever and know 'cape' world very good (as well as laws). And, yes, Flayer can't create iron from air, but his skills I think, quite higher than for Kayzer.

I'm not so sure, that somebody ofUndercovers have Great Weapons and Superb Fists. But anyway - the point is The Flayer is leader and "brain" of gung, while the "fist" is Wendigo or Hummersmith.
P.S. About costume - actually, it's just uniform which is comfortable for fight/ Also, it has psyhological reason - even if his not a cape, he s till part of their world. And he actually considered himself as a crime fighter (still) and he wear it also for memory about father.
P.P.S. Yep, but they still dangerous with good equipment. Oni Lee can garantee that.

So, edition version with backstory.
NOTE: English isn't my Native language, and an American reality I know mostly from movies. So, their stories can be strange.
The Flayer
Skills: as it was cuz I already spend more then 45 skill points.

Fair: Deceit, Burglary
Average: Craftsmanship, Perfomaces
Stunts:
-Martial Artist: As a result of advanced training, you are able to recognize many styles of martial arts, using Fists as a knowledge and perception skill focused on unarmed fighting. This enables you to make assessments and declarations
related to fighting styles and fighting culture using your Fists skill. This stunt may be used as a prerequisite for other Fists stunts.
-Lethal Weapon: Your hands are lethal weapons. When using Fists to strike an unarmored opponent, you are considered to have Weapon:2.
-Acrobat: Gain +1 on Athletics when using it to survive a fall. Also, gain +1 to attempts to dodge ranged attacks (throwing and guns), so long as you describe it colorfully.
-Fleet of Foot: When sprinting (page 212), gain a +2 to Athletics.
-Paranoid? Probably.: Gain +2 to Alertness when rolling against surprise.
-Riposte: On a successful defense with Weapons, you may sacrifice your next action to turn that defense into an immediate and automatically successful attack.
-Fast Reload: Provided that you have a supply of ammunition, reloads are rarely an issue. You take no penalty when reloading as a supplemental action (page 213); if you’re in a race to see who reloads first, or anything else having to do with your speed or ability to reload, gain a +1 on the roll.
-Blend In: You blend into a crowd easily. If there’s a crowd to hide in, you gain +2 to your Stealth rolls. This is particularly useful when Shadowing (page 143) someone on foot.
-Leadership: When you talk, people listen. When using Presence to command a group, gain +1 on the effort. Further, your efforts to coordinate a group are efficient, moving one time increment (page 315) faster than normal.
-Linguist: You may speak (and read) additional languages as if your Scholarship score was 4 higher than it is. You may take this stunt multiple times, adding four more each time. Up to half of the languages you speak may be obscure, rare, or dead, provided you can establish an opportunity to study them.
-Scene of the Crime: You have a practiced eye when combing over a crime scene. In such a circumstance, you gain +1 to your Investigation roll and arrive at your findings one step faster than usual on the time table (page 315).
-No Pain, No Gain: You can take a bunch of punishment before it starts to add up. You may take two additional mild physical consequences.
-Supreme Concentration: Your Discipline is considered to be Fantastic whenever Discipline
would restrict, complement, or otherwise modify another skill. This has no effect on your actual Discipline rating when the skill itself is being rolled.
-Bend and Break: When successfully breaking an object using your Might, increase the effect (stress, usually) by two steps.
-Takes One to Know One: You may use Deceit instead of Empathy to catch someone in a lie.
-Shake the Tail: When you are the one being followed in a car-chase, you have a real talent for sudden turns and daring maneuvers to shake off your pursuers. Gain a +2 to Driving in such a case.
Backstory: Nick van Dongen never want to be a villain. His father was the policeman, who was killed on duty, while his mother was early retired cape (she was crippled by supervillains).

He was also very smart, and graduated from high school by his 15. But as time passed, and the ability and did not show up. Even in very stressful situations, which have been staged for him by his mother, he stiil be human. Later, the psyhologist explain to women,   that a possible cause was the education of Nick - if he had some hidden powers, he could not open them in a trigger situation, because subconsciously used to rely on the skills acquired. It was just a theory, but the woman was broken - it turned out that she had destroyed the future of her son, thus depriving him of his childhood. Old injuries made ​​themselves felt, and soon she died.
Nick got a pretty good heritage, but he was squashed. He was alone, no superhero bunch was ready to accept the teen without  powers, and he actually didn't want to join to heroes. He didn't tell his mother, but he understand, how this system work. Status quo is the God, nobody will break the balance, etc... He was dissapointed though he understood to go from other side...
