CABLE

Cable shot his own son to save someone else. In the Askani future, Cable — Nathan Summers — raised his son Tyler Dayspring with his wife Aliya (Jenskot) in the Clan Chosen, fighting Apocalypse's New Canaanite regime. The villain Stryfe — Cable's own clone — abducted the teenage Tyler and had him mentally corrupted. Tyler resurfaced as one of Stryfe's soldiers, holding Cable's friend Dawnsilk hostage through a neural link. With no other way to free her, Cable shot Tyler.

Tyler survived — and never forgave his father. He time-travelled to the present day and reinvented himself in secret as Mr. Tolliver, a masked arms dealer (first seen in X-Force #5, 1992). From the shadows Tolliver hired Cable's old mercenary team, the Six Pack, and set them against Stryfe — a mission that shattered the team and turned most of them against Cable, exactly the revenge Tyler wanted.

Tyler returned again as Genesis (debuting in Cable #19, 1995), declaring himself Apocalypse's heir. Leading the Dark Riders, he tried to restore Wolverine's adamantium and erase his mind to make him a Horseman — the experiment drove Wolverine feral, and Wolverine killed him. Some accounts even question Tyler's parentage, suggesting Stryfe himself may have been his biological father — Marvel has never definitively settled it.
