IGN wrote, "America has Captain America, so it's only fair that England has Captain Britain. But Brian Braddock is no mere super-soldier. He's empowered by the magic of Merlin and his daughter Roma to defend England from threats both mystical and mundane. These days, Braddock leads the members of MI:13. And as the only Marvel hero to receive the benefit of Alan Moore's pen, Captain Britain enjoys very rarefied status in the Marvel universe." Max Nason of CBR.com stated, "Plenty of people assume that Brian Braddock, otherwise known as Captain Britain, is just a British knockoff of Captain Steve Rogers. Well, that couldn't be further from the truth. Captain Britain has a wholly unique and fascinating origin story, much different than that of Captain America. To go along with his incredible backstory, Braddock's powers also help set him apart from not just Rogers, but most Marvel heroes. The evolution of Captain Britain's abilities is just as, if not more, interesting than the powers themselves." Jack Malvern of The Times stated, "Captain Britain's nemesis turned out to be lack of popularity [...] and his adventures ended after a year."
