Iceman has improved a lot over the years and he went from being the new kid on the block to an experienced threat who shouldn’t be taken lightly. He can flash freeze opponents in an instant. Although, due to Rosalina’s space durability, that likely won’t be much of an issue, if it is one at all. It is really tough to say who has the edge in this matchup. Rosalina has her barrier and starbits, but will that be enough! I guess, I will say yes since she can also reflect any ice blast that Iceman tries. Rosalina wins.
