The Super Powers brand was created for the toy line but - in that clever toy marketing way - expanded to encompass numerous products and manufacturers. It probably did a lot to bolster the public profile of DC's characters at a time when Marvel's heroes were still struggling to gain traction despite the odd animated series and the late-seventies live-action shows.
The collection did reach the UK but didn't seem to have anything like the same impact. The Hanna Barbera animated show (a rejigged version of the long-running SUPER FRIENDS franchise) didn't cross the Atlantic despite the success of SPIDER-MAN AND HIS AMAZING FRIENDS on the BBC and THE HULK on ITV.
Marvel may have played a part by nobbling the success of a British Super Powers comic. Around this time, the Annex of Ideas acquired certain rights to reprint DC strips. This deal, which fandom initially anticipated would see a number of regular DC comics issued under the Marvel banner, never actually amounted to much and - as far as I know - only spawned the 1985 MASTERS OF THE UNIVERSE SUMMER SPECIAL and a solitary SUPER POWERS ANNUAL (which I'll cover in more detail in a future post) which seemed to suffer from very limited distribution at the time (I never saw a copy) and rarely turns-up today.
Whether Marvel or DC suddenly grasped the implications of the deal and terminated it or whether the early ventures were deemed a value and the venture ended is unclear but both the DC and MASTERS OF THE UNIVERSE licenses eventually landed at London Editions (despite the fact that Marvel US took over the US MOTU strip license, through the Star Comics line, in the States).
The most likely explanation is that Marvel UK were also publishing a British edition of MARVEL SUPER HEROES SECRET WARS, loosely based on the Mattel action figures (Mattel only did the deal with Marvel to act as a spoiler for the DC/ Kenner tie-up) and - understandably - favoured supporting their own characters and licensing deals rather than simultaneously publishing a rival title promoting a rival (and - frankly - superior) toy line.
