tough decision, one hand you got a guy who scares the crap out of the lords of order and chaos, and even the gauridans, who has
moved planets
controlled millions of superman level beings
can mind controll mr miricle who claims he can take on any mind controll save darkseids
can throw people out of the universe and lock them out
teleport anyone anywhere he wants
beat a guy named mantis who womped orions entire team
turned a lobo clone into stone
vs
guy who can punch dimensional walls down
immune to magic (dont know about mind controll must be immune or pretty strong against it since he fought MM)
can also move planets but uses his hands
beat MANY GL's
very hard fight i think darkseid would win, SBP can move planets darkseid can do it faster, superboy prime can punch out of dimensions Darkseid can travel through time and space easily, darkseid is not as strong, SBP might not be strong enough to compete with Darkseids mind controll either, the guy controlled millions of daxamites who are superman level, SBP is immune to magic but what about transmutation, all the guys he battled where they on the level of a none jobbing darkseid? Also the omega effects wont work on him but they can still hurt him like they did the spectre, when darkseid puts him down he can just keep smacking him down till he finally is to weak to do anything.
Darkseid doen'st need the Omega Effect for matter manipulation. He can also harden Time and Space. He did this to hold Ares with the Godwave, who was waaaaaaaaaaay more powerful than SBP. SBP is trapped in Time and Space Like amber and then Mentally dominated into forgetting that he has any powers at all.
Why cant darkseid use the omega effect?Anyway wicked fight,earth shattering power, but darkseid would win. With the Omega effect, SBP would start crying and rush him, Darlseid would calmly teleport him into a sunless dimension and beat the horse$#!t out of him, kill him, bring him back from the dead and do it again. Without it , Darkseid could toe-to toe SPB, and he is also a master tactician. He's start by outsmarting him, continue by out strengthing him than beat him into the dust of apokolips and kill him.
