>>110482356The Punishers are all given one opportunity: To save Frank Castle's family. Not their own, of course. An alternate Frank Castle's. To succeed, they'll have to defeat a cosmic horror bent on making everything dark and edgy.
They pull out all the stops, a lot of the Punishers die, but they make it. Our Frank briefly meets that universe's Frank, tells him to "Take care of them" and vanishes. That Frank and his family live to a ripe old age, and Castle dies surrounded by his grandchildren.
He never tells them what happened on that day.
