Type: The real deal
To defeat Phantom Zone villains (oh you know, just Zod and Faora and stuff), Superman and Wonder Woman get Hephaestus to make them magic armor. The suits have two basic powers : Being undetectable to super-senses, and allowing the release of all the kinetic energy punched into them back at the original punchers. That last function destroys the suits.
Spoiler: It's a cool use of Diana's contacts (which are so integral to her own series), but plot-wise, doesn't really get them out of their jam.
