Suggested by Sonic Rosalina is a cosmic being and all so you would expect her to be reasonably strong, but I still don’t think that she is quite ready to take on someone like Bulbasaur. Bulbasaur is just too skilled at this point and he can even evolve into Venusaur. At that point he has too many long range options that could stop Rosalina in her tracks. She isn’t quite quick enough to dodge so that’s when the match will end. Bulbasaur wins.
