Mr fantastic would say:

"What hell is This guy talking about?Johnny would bé dead even with a depowerd Superman!"

This guy thinks superman is a Simple Kryptonian?he got 33 years plus of sunlight power store,its no easy task to depowerd him and when Thats happen its just bad writing,and yes Johnny probably could find a way to manipulate some red sun type of energy but supes would wreck him easly still,he is just and ant or less than that.

Do you know who is captain atom?did you ever Saw JLA unlimited?captain atom is a Godlike hero few can take and can manipulate red sun even with that capacity to hurt supes that just dont depowerd him easly.

Do you know Superman absorved Solaris black sun?do you know Superman flew throw a red sun and survived easly?

Do you know Ray a hero way more powerful than Johnny a light based power hero with unlimited power can power up supes just by standing by his SIDE,he can too manipulate supes power to depowerd him still its a guy with unlimited power scale and its not easy for him,not a ant like Johnny.

Do you know the new God lightray?do you know he to hás power based on sun rays and can power up supes just by standing at his SIDE and he hás no minimal chance to beat supes ,he would call you crazy, darksied can manipulate every type of energy and that power did never nothing to him again supes,só i ask AGAIN:

"What a f...k are you talking about?"

And poor Marvel you say they confirming?are you deaf?even supes rippoff less powerful killed the MCU and you come here talk about a ant chance of wining supes?do you drink water sometimes?
