This made Terrific three times more expensive than the 3d cover price of competitor DC Thomson's perennials The Beano and The Dandy.

The Marvel material in the Power Comics titles were frequently edited to replace American spellings and slang with their British equivalents.

Dialogue and/or images were also changed occasionally to remove snags in continuity caused by the lack of synchronisation between reprints of different storylines.

Marvel credit boxes containing the names of Stan Lee, Steve Ditko, Jack Kirby, and the like were invariably deleted from the splash pages; the space they occupied was either left blank or covered with drawn-in artwork.

Apart from the compulsory copyright acknowledgment in small print, the name "Marvel" was never mentioned — wherever it appeared in the strips it was changed to "Power".
