Surfer would basically murder Superman within the Sun.
Surfer absorbed the blummin OAN battery thingummy!
(saw the scan, never read the crossover, but how far off can I possibly be eh?)
Hulk might just punch out the Sun (it's not impossible, just blummin' irritating).
Strange could do some magic trick or other, I'm sure 😐.
anyone who can destabilise Superman's solar-energy collecting cells could effectively poison him, as per the S1M thingummy.
