Well if we look back at the episode when they travel to The Forge of Creation, I'm pretty sure Paradox told Ben, Gwen, and Kevin that while they're there, they wouldn't age, be hungry, or thirsty. So while in The Forge of Creation, the Celestialsapiens shouldn't be able to die and the only reason Alien X could be destroyed is beacause he is not in The Forge of Creation and is in a whole different universe. That why the space around Alien X was disappearing in So Long, and Thanks for All the Smoothies was because Ben wasn't in the same universe as The Forge of Creation and was just on plain old Earth. This would also explain why Psyphon and Vilgax possibly could've killed Alien X was because he wasn't in The Forge of Creation. This hasn't been confirmed anywhere, this is just my opinion and is one of the only theories that could make sense in the situation of Alien X being able to be killed. So instead of the topic being "Can Alien X die?" It should be "Where can Alisn X be killed and/or destroyed?(whichever you prefer)"
