THUNDEROUS ARRIVAL
Start the game with Superman on his card instead of the battlefield. When a friendly figure is targeted for an attack, if Superman is on his card, once per game, you may place him adjacent to the attacking figure. You may then roll one unblockable attack die against that figure and that attacking figure's turn immediately ends. After rolling, you may move any of your unrevealed Order Markers to this card.
Thoughts after playing him post con:
The red above I believe is a needed change. Right now the interaction with the Billy Civilian design gets wonky, where he could potentially come back on the board with that Billy out there (gets especially weird and unclear if Billy is negated).
The blue is a bit of a power up, but one that I think is needed. He originally functioned this way, but we shifted it to a 50/50 shot at the turn stop in part because there was worry that he'd feel too swappable with JL Superman I. So the change was made, but we later realized he didn't give out JL markers. It is just kind of a sucky feeling to have the first section of his card basically amount to "oh Billy's here, he's late" half the time when it takes up as much space as it does. I could also see ditching the unblockable and just sticking with a turn end, if that feels like a lighter shift there.
