When you’re killed by your mentor, but still need to fulfill your cosmic destiny.
Here is Jack Flag in what I’m calling the 91600 Timeline AU. I will go more in depth with what this Au entails in another post. Just know, the entirety of marvel comics since 1961 occurs from 2002-2022.
Jack’s life is mostly the same as the 616, with the exception that during Heroes Reborn, he and Free Spirit take over the mantle of Captain America while Steve is MIA.
The biggest change, though, is that after he is killed by Steve in Hidden Empire, he gets resurrected 7 months later, where he wanders the galaxy as Starfall. He eventually realizes that the universe is breaking and he needs to gather the Infinity Gems, essentially taking Gamora’s place in Infity Wars (2018).
