@naladahc DC's first issue of Shazam back in the mid-70's actually explained how Cap and family wound up in current time without aging. Sivana created a Suspendium bomb that would freeze time for anyone caught in it. Naturally it went wrong, so not only were Billy, Mary, and Freddy caught in the trap, so was Sivana and his two kids, plus Mr. Tawny and a lot of Fawcett City town folks. They were trapped in the Suspendium for 25 years, not aging during that time.
@phantomkitty oh I know all about that but it is too much of an unbelievable thing for me. The fact that every important character to the IP got caught in the suspendium of and then of course could be in contemporary stories was a bit ridiculous.
