First of all, ugly is subjective. Second, "brown person" is potentially offensive. Third, there are some distinct differences that separate Sky from Zoey, like she does make mistakes and is not portrayed as perfect in terms of skill and actions. She has her faults, the writers seemed like they did not mind writing Zoey as if she can never be faulted. Sky is probably a good deal more intelligent, and has a genuine competitive streak, with physical abilities that are justifiable by her Olympian training. I'm not saying that she's a great character, that's up to the individual to decide. But at the same time, not quite a Zoey clone either way.

Though yes, both had romantic arcs I'm sure most of us here wish were never major focuses.
