absorb the sun?eer
er, no . . . "unless i contain it . . . it could turn into a moniature sun" sounds a bit like hyperbole, but that aside, it was a nuclear reaction that MAY have turned into a 'mini' sun IF he didn't stop it first, which he did.
how in all the hells did you get -- he could absorb the sun -- from THAT scan? 😑
i doubt he'd want supes touching him, as snoop said, to take him to the q-zone. if as you say he could drain supes, he could ALSO do the same to ss -- except he couldn't because ss replenished his energies as quick as they were siphoned off. what makes you think supes absorbs energy at a rate less than ss? and as snoop pointed out, he gets energy from ALL the yellow and white stars, not just our star.
so . . .
(1) he can't 'drain his cells'. if he could he would have been able to do the same to ss unless you can prove supes energy absorbtion<ss ambient cosmic energy absorbtion
(2) no, he cannot 'drain the sun'. drain the sun? he'd also of course be killing everyone on earth even if by some MIRACLE he could do it, so in NO WAY is it viable.
(3) dumping in the q-zone would mean letting supes grab him -- he'd have more to worry about than taking him to the q-zone if that were the case.
(4) he could try and make a strong enough construct but if thor would smash them, supes could, and he would likely exhaust himself with the effort.
supes wins.
