Some years ago, Daken was dying when his powers go crazy, and he kills himself in front of Wolverine to take revenge against his father. It was a forceful and disturbing death as culmination of the days in which Logan's past punch him in his face, with the Red Right Hand all those stuffs.
But then, Daken reappears in Uncanny X-Force, speaking of himself like a child, being confident in Sabretooth (instead of good old Machiavellian Daken) and telling Wolverine of a childhood that it wasn't the same that we know. Remender never explains how Daken was alive again, but in previous comics Deadpool investigates White Sky, a private agency that clones, programs and grows specific individuals for their clients.
That give me the suspicion that Remender's Daken is not the 'original Daken', but a 'new Daken' created by Sabretooth with White Sky services like 'All-New Fanthreemex' to torment Wolverine. This could explain why Daken is alive again and why he doesn't act exactly the same. What do you think?
