• Powerful Powers: GMs should be lenient on the mechanical limits of Gifts, allowing for more customisation of Effects than usual. All Heroes aside from E-Listers can take Newbie, Novice, Seasoned, Professional and Veteran enhancements. 
• More Bonuses!: Bonuses to the same dice pool do stack, unless granted by the same Effect. 
• Hero Tiers: In the world of the Others, Heroes and Villains can be separated into various levels of power, depending on the sort of threats they can face, or the threat they are to face, separated into three categories, and then two subcategories. STREET LEVEL: These Heroes deal with local threats. Robberies, muggings, some gang violence. F-Listers (0-3 GP, +0EXP) E-Listers (4-6 GP, +0EXP), and D-Listers (7-11 GP, +0EXP) fall here. CITY LEVEL: These Heroes can still deal with Street threats, but are also picked up to deal with villains capable of levelling buildings, and similar tiers of damage. C-Listers (12-20 GP, +30 EXP), and B-Listers (21-30 GP, +60 EXP) fall here. COUNTRY LEVEL: These heroes are called upon to deal with the toughest threats, those with the power to flatten cities and threaten global safety. A-Listers (31-44 GP, +80EXP) and S-Listers (45+ GP, +100EXP) call here. 
• Terminology: 'Lasting' Mind Damage or Injuries are those which must be healed by natural means. Any Gifts which restore Mind or heal Injuries can only heal 1 point of this damage, or reduce it by 1 depending on the feature. For example, 3 Mind Damage can only be reduced to 2, not 1 by Compartmentalising, and Regeneration can only heal a Lasting Severity-6 Injury by 1, the rest must heal naturally. Gadgets are Legendary Artefacts, and using Gadgets means having those Gifts or an Artefact Crafting Gift.
• Limit Break: A Hero with at least 1 Gift receives the Asset: All-Out Strike and the Asset: Sustained Limit Break for free. A Hero can only Limit Break if they have had to roll Self-Control against a Trauma or Limit in the last minute. The exact benefits of a Limit Break may change, but they must match with an appropriate penalty. 
• Asset: Limit Break (All Out Strike): (As part of a Power usage, you can roll with double your usual dice pool, ignoring up to 4 1s. However, after this Gift is resolved, you immediately take a Lasting Severity-6 Injury, plus 3 Lasting Mind damage and an appropriate Trauma.)
• Asset: Limit Break (Sustained Limit Break):  (As a Free Action, you can enter Sustained Limit Break for 1 minute. For this time, you have +2 Outcome on all actions, ignore either Body or Mind Penalty (or ignore the effects of one Battle Scar if Grit does both), and regain 1 Source each round. However, at the end of a Sustained Limit Break, you must roll a d10, Difficulty 6. On a failure, you receive 4 Lasting Severity 6 Injuries, and 4 points of Lasting Mind damage. On a success, you receive 2 Severity-4 Injuries, and 3 Mind damage.) 

• Little In a Big World: Any Heroes who take the Giftless Liability receive an additional 30 Experience to spend, and gain two features. The Asset: Stroke of Luck, and the Asset: Underdog.
• Asset: Stroke of Luck (In addition to your Will to Survive, you also gain a resource once per Mission with the same effect named your Stroke of Luck. Once per Mission, when you would suffer an Injury of any Severity, you can reduce the Severity to 0.)
• Asset: Underdog (A number of times per Contract equal to your number of Victories (minimum 1), you can increase the Outcome of any roll by 2. Once per contract, you can increase this benefit to a number equal to half your Mind score (minimum 2., rounded up). In addition, any time you enter Combat with a Villain, you can make a Free Action each turn to Evade (with a -2 Dice Penalty), until you deal 6 damage cumulatively to them, unless the villain already has knowledge of your capabilities. 
• Power Sources: Most Heroes and Villains get their powers from Substance B, the drug originally created by the SOS in the Golden Age to make Heroes. However, that is not the only way powers are acquired. Sometimes, Heroes use Gadgets, advanced technology beyond the usual modern to create effects. Additionally, some have more esoteric sources, with even some theories stating Substance B is both a stimulant...and contains some other unknown, even supernatural properties.
• If your Hero gets their abilities from Substance B, you gain the Asset: Take a Hit (You gain your abilities from usage of Substance B. If you have access to a vial of Substance B, you may take it to access your Limit Break abilities once per vial with no consequences, however you roll a 1d10, Difficulty 2. On a failure, you cannot use Substance B in this manner again. Any additional vials may grant additional benefits, but at the cost of increasing this Difficulty by 1, and other penalties.) 
• If your Hero uses Gadgets, you gain the Asset: Dismantle (You may alter your Legendary Artefacts, changing enhancements and even fully replacing effects with others in between Missions. In addition, you may, once per Mission, regain a point of Source or Battery for free as a Quick action, charging up a Gadget.)
• If your Hero uses other methods of gaining Powers, they gain the Asset: Alien Origins (Your powers are strange. Hard to quantify and predict. You may, at any point, ignore a Drawback of one Gift for that activation, but you also must choose an Enhancement on that Gift and lose access to it for 1d4 rounds. You may also use this effect to gain an Enhancement you do not have, but must choose a Drawback as well, gaining the effects of both for 1d4 rounds. There may be different penalties for ignoring Drawbacks or Gaining Enhancements, such as up to 2 Mind Damage, or a Severity-4 Injury.) 

The Golden Age of Superheroes began in 1942, when Germany's delving into the Occult unearthed strange forces, ones used to empower a super-soldier named Ubervolt. Ubervolt had the powers of lightning manipulation, and the ability to seemingly generate vast amounts of electricity from nothing. In addition, the more energy it consumed, the larger it grew, peaking at a staggering thousand feet tall! It seemed like there could be no opposing this threat, until....The Comet. Another strange being, this time one wreathed in golden fire and moving as fast as even Ubervolt's lightning blasts. The Comet fought Ubervolt and won after a long battle, leaving pieces of itself wherever it went.

This clash of titans, once over, had researchers scrambling to use whatever was left for the war effort. At first, this was the Heliotron, a robot powered by collected pieces of the Comet's body, able to store a fragment of that incredible power and use it to create flames. Soon after, in 1944, the first human testing began in Britain with refined pieces of the Comet, and various stabilising elements to stimulate the body to react and adapt to the power (now known as Proto-B). This experiment created the first human superhero, Catalyst. Sharing many powers with the Comet, and Heliotron, Catalyst could manipulate energy, absorb and reflect light to grow in power, fly, enhance his physical abilities, and much more!

Catalyst, after aiding in the war effort, was also deployed to deal with more strange threats, and villains performing their own experiments to create superhumans. When it became too much for just one hero, Her Majesty's Chosen was formed in 1948. With more experimentation, more stable forms of Proto-B (Aka Substance A), were used to birth Sea King, an aquatic hero with water-manipulation powers, Mercury, a speedster, and to enhance the intellect of Rocketeer to allow her to create some of the first Gadgets, such as her rocket suit. 

HMC-I continued working until the 70s, facing villains such as Quantum Shaman, Grand Richter, Gigahertz and many more! However, the team dissolved near the end of 1972, when Catalyst was killed by Doctor Crossbones, a mad scientist and master-class inventor, marking the first hero death and beginning the end of the Golden Age. After this, HMC-I remained active, but later in a confrontation with the same villain, all but Rocketeer also met their end, but managed to defeat him in the process.

Between 1970 and 1991 was considered the 'Dark Age' of superheroics, with no national team and many different powerful heroes and villains fighting for dominance after the power vaccum left by HMC-1.

HMC-II, the second team, came online in 1991, consisting of the super-strong and durable Baldr, the shapeshifter Red Dragon, who usually makes her form that of a scaled, fire-breathing winged humanoid, Sonic Saint, an armoured Gadget-user and energy manipulator, and Rocketeer II, the daughter of the first Rocketeer who inherited her genius intellect. All were created with the new Substance-B, which is now used by the S.O.S (established in 1965 by HMC-I) and its subsidaries, especially after the Parahuman Initiative which allowed more superhero teams to be legally active (signed October 1991). This is also the start of the Modern Age (also called the Silver Age, or still the Dark Age by certain people) of superheroics.
