The Serious Man
 
Captain Chronos actually hesitated in recruiting The Serious Man, because his world's end was very dangerous even to Chronos. His world was literally dissolving into nothingness, his entire universe ceasing to be. But nevertheless, the good Captain felt it was the only way.
The Serious Man's powers are subtle. Everything around him becomes, for lack of a better term, a little more real. Powers that warp the laws of physics stop being able to do so. Chemistry starts working on very hard and strict laws. Energy beams can exist, but if you want to bounce a shot - well, better make sure that mirror is pretty much optically perfect.
Why was this important? Because he was up against a force that was making everything UNreal. making it fake, false, a creation of a diseased mind. The universe cannot hold itself together without effective constants, and now there were no constants. For years earlier, a strange and warped mind had discovered a way to impose his worldview on the entire universe. Now, The Serious Man must find and stop that crazed individual.
He must stop Foxbat.
 

No one else has mentioned it, so:
 
D&D was reasonably balanced for about 2 years, between the release of 4e in 2008 and the release of Essentials in 2010.  Even then, it didn't return to the profound, perennial imbalance you alude to until the official release of 5e in 2014.

Balance is overrated and not always desirable.

Welp, they are heading for the life boats. This just dropped.

As we look ahead, it becomes even more important for our actions to represent our values. While we wait to see what the future holds, we are moving forward with clear-eyed work on a new Core Fantasy tabletop ruleset: available, open, and subscription-free for those who love it—Code Name: Project Black Flag. 

Already on my standard spiel.  I also mention how HERO works for any genre, as I've seen a number of 'I want to use 5e to play this extremely not 5e game' posts like Sci-Fi or Low/Gritty Fantasy.  Hmm.  Thinking about it a little, I'd say that the rules for HERO enable both players and GMs, where the D&D rules seem more to restrict them.  DnD says you can't do X (say, cast Fireball) until you're 5th level, and know how to cast a bunch of other spells.  Hero? "I know one spell, Fireball."  DnD: "My character can't get superhuman strength without several levels and/or a magic item." Hero: "My demigod started with a 40 Strength.  I can juggle cows." Expensive if you're using NCM, but possible.

Just how Open Source is Fuzion?

One D&D to rule them all, One D&D to find them,
One D&D to bring them all and in the Dorkness bind them,
In the Land of WOTC where the Hasbros lie.

Oh, right. Need a prompt for the next super-villain team, right?
 
"Sweethearts" - three couples and one polycule (at least three people in the polycule) whose powers and super-villain themes were all derived from, and centred on, the fact that they are dating/having sex/whatever their relationships are. The team formed because these super-villains all found a common ground in the fact that they prized their love (and probably, in some cases, the power it granted them) *far* more than the super-heroes "Justice" and an incredibly powerful team of super-villainous spouses/lovers would be a perfect way to demonstrate how right they are and how wrong the heroes are.

If they are already playing (modern) D&D, they are already playing
a game more complex than Hero.

The only issues are the learning curve and any nonsense they've picked up from the net.

The big questions are: why are superheroes/super soldiers not on the front lines of the war effort? In Marvel the answer is, they were but the adventures were top secret ("The Invaders"). DC's reason is The Spear Of Destiny, which kept superheroes away from Germany. Champions history is that darn spell which kept allied superheroes from axis occupied areas.
 
My reason is that the superheroes are great propaganda pieces and are much too valuable to risk their lives in the front lines. That doesn't mean they didn't risk their lives in important activities during WW2. It is just they were deliberately kept from the front lines unless an operation absolutely needed their skills. (Note: properganda agents won't work in a campaign where superheroes are supposed to be a hidden thing.)
 
Besides, it's easier to vary adventures when they have a home base and not moving with an infantry or such.

Any science which is distinguishable from magic is insufficiently advanced.

Some great suggestions.
 
Another set up I've seen on the mechanical side is an Inspiring Leader with 10  extra points of  Presence for Defense only, Usable by others named something like "With him on our side, we can face anything". Mind you he was less a tactical genius and more an icon.

Wouldn't the Green Beret be a "Contact"?
 
The Mute Girlfriend could be quite interesting. She probably still wants her opinions known at least to her friends, and might become one of the fastest texter in her social group. She might also pursue other interests like art or writing as a channel for self expression. The problem with a lot of "disabled" Characters as they become ":saintly, but we all have our flaws.  Does she follow gossip? Is she an online troll, because no one would suspect the silent girl? A lot of GMs make the DNPC Girlfriend a Damsel in Distress, but, what if she was the instigator, due to something she posted online? 

58, and started with first edition, day one, and have the flyer from Pacific Origins to prove it.  😁

There should be a "fall down the rabbit hole" side effect.

In my old champions campaign, since so many mutants were the result of environmental contamination, the EPA was given jurisdiction over superbeings...

With any D&D adaptation, you gotta check the spells... 
'Obviously' he was using Telekinesis.
 
Cute that they used Witch Bolt for Sith Lightning... I've seen players make that connection, before...
....except, canonically, Vader can't use it.
 
 

The Dissidents ideals seem a little behind the times.  They could update to anti-globalization, anti-"fascist," de-platforming, defund/de-militarize police...
 
...and some old issues are back on table,  like abortion.
 
They could take down media/internet infrastructure to silence anything from right-wing rallies or a campus lecture, to advertising campaigns.  
 
Several of the heroes could catch their attention.
A real Angel? A woman, at that? What's her stance on abortion?  
Thumpers secret ID could be targeted for kidnapping, blackmail, or some more elaborate plot.
Rainbow Warrior and Escudar might be targeted for recruitment.  You could have the Dissidents (or just some of them) come in and help them against a villain with military or corporate ties or who espouses the right ideology to draw their ire.

In case it helps, the hero player characters in my campaign are:
Angel - female actual angel with wings and martial arts skills, also Streetwise (and a bit of Wealth, for some strange reason) Escudar - male Hispanic martial artist with Code vs. Killing and gets enraged at people harming the weak and innocent; sneaky but no real streetwise or investigative skills yet Flux - female interior designer with vibration powers (blasts, flight, vibration-based radar, has Conversation skill Jack Frost - the "Face" of the group, a male attention hound with cold/ice powers and major musical talents Rainbow Warrior - non-gendered public ID (is on the Board of Supervisors for the city) with light powers (blasts, teleport, invisibility, holograms), has Bureaucratics, Conversaton, Persuasion, and Streetwise skills Techtronic - male technopath with cyberkinesis / electrokinetic powers (taser-style Entangle, machine psionics, camera vision), has Electronics and hacking-type skills Thumper - male brick able to manipulate his own size and density (so, growth and shrinking, density increase, desolid), very wealthy with minor noncombat skills (Conversation, Stealth) but not much in the investigative field They have an "office manager" (Wally Burke) who has the metahuman talent that he can frequently (but not always) hear local police band transmissions - from about 15 minutes in the future.  So the team often gets a heads-up when things are going on, with enough notice to hopefully arrive in time to save the day.

I agree strongly.  You cannot hold a player's personal limitations against their character. If someone is terrible at coming up with soliloquies for their presence attack, consider the best they can do to be a great one.  Don't treat their soliloquy as terrible just because they are bad at it.
 
Related: puzzles and riddles that test the player's ability to solve them instead of the character's.  This is ROLE PLAYING and as such you should be checking how good the character is.  I play RPGs to do things and go places I cannot personally - its a sort of wish fulfilment as well as storytelling.
 
I could rant on this for pages as it is an enormous pet peeve with game designers.  Its okay to put puzzles and riddles and such into games as long as you allow the skill of the characters to produce hints, details, and information to help solve the problem.  Requiring the players to figure out your perfect riddle or fail is not role playing, its you being a jackass as a GM.
