in the remainder of the series. However, later Alpha Flight series did not make use of the concept. In 2006 the concept was again revived by writer Mark Millar as the main plot point in Marvel's 2006 Civil War crossover. In preparation for that storyline a new version of the Superhuman Registration Act has been widely mentioned across various Marvel titles, with the issue being most widely discussed and explored in The Amazing Spider-Man #529 - 531 (April - June 2006) by writer J. Michael Straczynski. Issues, allegories and metaphors When the topic of the original Superhuman Registration Act is debated in Fantastic Four #335-336 the issue is explored in a national security context, with the utility of such a law being challenged. In the comics the Fantastic Four argue that super-heroes are already a hugely benevolent force for society and such an act would be unnecessary and possibly counter-productive. The National Rifle Association (NRA) is also against the act, stating that the Second Amendment to the United States Constitution's protection of the right to keep and bear arms in the United States applies to superpowers. An NRA representative testifies to Congress that "if powers are outlawed, only outlaws will have powers". When the issue of an SRA was raised again in Amazing Spider-Man #529 - 531 the prospect of a new SRA is explored once more from a security perspective, with reference being made to the fact that super-powered individuals often wield abilities which have massively destructive potential for use, making some mechanism to regulate their activities necessary. The writer of Civil War, Mark Millar, has stated that that storyline explores the civil rights implications of the SHR as previous stories have done, but also explores the other side of the argument in more depth, in particular how Marvel super-heroes are, absent an SRA, illegal vigilantes, lacking proper legal authority or oversight. Terms of the registration acts In a June 2006 interview Civil War editor Tom Brevoort confirmed that registrants to the act were required to reveal their identities to the government (but not the public) and they have to undergo some basic testing or training and satisfy certain (as yet unspecified) standards before they gain legal authorization to continue to use their abilities to fight crime. Government employment is not mandatory, though it is available to those who wish to take it. This has not remained consistent, though,
