Are you like stupid? The only weaknesses he has it the specific frequency that required months of finding and a alive viltrumite to ever find, and the scourge virus that you need to go the the specific people in order to get it
Combat And Endurance Should Go To Flash. He Ran As Darkseid's Generator For 2 Years. A Beating From Thawne, His Leg Broken From Superman, And a Punch From Doomsday.
Hulk from "Hulk and the agents of S.M.A.S.H." vs DCAMU Justice League + Darkseid and finally Doomsday. Also, have him solo everyone as he seems to be able too. PLEASE!
No the parademons that he fought were weaker and weren’t fused with doomsday and he admitted superman could kill him easily if he was trying with kryptonite
