X-Men: The Animated Series: Phoenix Saga, Part 5: Child of Light

DKen gets pulled into the Crystal, and becomes one with the universe inside it. Phoenix explains that the Crystal will suck all of existence inside of itself and create a new, lifeless universe to replace the one that was destroyed. On Earth, Storm and other heroes try to restore order as life starts to collapse. D'Ken, seemingly limitless in power, easily fights off the X-Men until Phoenix restores herself to power and helps the others escape.
