Our Hero has been trapped, powerless, in a dungeon...
...but now, all hell is about to break loose in the cataclysmic conclusion!
1) Marion (ButterFly) Michaels says in a thought balloon that she met Hell-Rider "..while I was making like The ButterFly!"
Not in the book as printed.
Perhaps there were a couple of pages cut for space, but that's not what happened in any of the connected stories in #1.
2) Marion doesn't have time to don her ButterFly costume and join in the fight.
Just as well since she didn't have time to refuel or recharge the costume!
3) Deke of the Wild Bunch says he recognizes the unmasked Claw...except Deke never saw the Claw unmasked!
The concluding chapter of the multi-part story from Skywald's Hell-Rider #1 (1971) was written by Gary Friedrich and illustrated by Ross Andru (pencils), Mike Esposito (inks) and Bill Everett (greytones).
