Actually thanks for posting that it only shows that it may make him stronger or it might actually kill him. It's a 50/50 shot and in that other scan it shows him dead. The last two lines in the narration explain that completely. "It may even explode, the same holds for Cyclops. "
Also: Storm's lightning is low-octane regular energy
Your hateful lies at work again I see. Storm could rip Cyclops into bits and pieces if she wanted to, just by making a pressure differential outside or inside his body. And while Cyclops used to absorb solar/cosmic energy to fuel his blasts, they don't seem to work that way anymore, as the more recent issue shows.
Low octane energy that is five times hotter than the energy Scott is used to absorbing.
Storm can shift pressure gradients with less than a thought(see that old issue of Wolverine where she blew up a house while those gangsters were pointing their guns at her), and block his optic blasts. There is nothing he could do to stop her.
It does the job.
