Suggested by Destroyer Itachi has a lot of Sharingan tricks up his sleeve which could pose a threat to Raditz if the villain isn’t careful. He will have to really move with caution if he wants to survive this but the difference in their destructive abilities will be key here. Raditz can always destroy Itachi from afar or just speed blitz him. Raditz wins.
I admit, I don’t see any way Itachi could win. But he’d put up a good fight.
Sharingan certainly has its limits after a while. Raditz is just too strong
