For comparison, an RPGnet thread once led to me creating a particularly Scottish superhero team, which looked like this. A just-happen-to-be-from-Scotland group would have been quite different.
The Lions Rampant: Scotland's secret defenders
HQ: Hermitage House, Edinburgh.
A mystical team formed to defend the land against invasion by the Unseelie Host, the Sluagh and the Giants.
Name: Sir Gawain of Lothian and Orkney. Apparently he means it.
POB: Nordelone, Orkney
Archetype: Martial Artist - European knightly martial arts
Inspiration: Gawain from The Knights Of Pendragon (first series)
Appearance: Big loud red-bearded man in armour
Major Power(s): Superhuman strength and combat skill, rapid healing
Flaws/Drawbacks: His strength waxes and wanes with the rising and setting of the sun. At noon he has the strength of twelve men, an hour earlier or later it's eleven, another hour it's ten...
Quote: "Come on then, one and all! I have faced your betters a thousand times!"
POB: The shadow of Ben Nevis
Inspiration: Raven, Teen Titans
Appearance: Beautiful young woman with long red hair, dressed in white
Major Power(s): Flight, telepathy, tracking, fear attacks, senses channelled through familiar (crow), immortality
