Savage Brian, I have, my friend. Tight stuff, though I like Invincible more. Also Una, I suspect Mark may interfere with events and that would cause alternate events to happen. For example, it's possible Eve can die or Rex Splode stays alive, Viltrumites take over Earth. Sounds like the Butterfly effect when I think about it XD
I suspect Mark may be in a coma or near death while the reboot happens. Something will happen that causes his consciouness be transferred to the moment of he got his powers. Raiden did it in Mortal Kombat 9 before the events of Armaggedon and transferred his consciouness to the 1st Mortal Kombat Tournament, causing a reboot. I suspect that it may be focusing on the other people's lives while he is in a coma like Terra or Eve, Allen, Thragg, Nolan, Viltrumites, Robot that sort of thing.
