NEVER ENDING (2013)

"It's all down to this: the driven-yet-demented hero Chuck Baxter versus mortality and his own superpowers! Can evil scientist Archibald McCrae achieve his life's goal and kill the earth's only unkillable man? And when Chuck's past comes to haunt him, how will he respond? Either way, this is the end."

"Evil genius Archibald Crane's goal has been to kill the seemingly immortal hero Charles 'Chuck' Baxter-and now, shockingly, it's Chuck's goal, too! Earth's only superhero makes a devastating deal with the devil, as the past comes into focus and Chuck's losses become too much for him to cope with!"
