Star Fleet isn't a cartoon, but a series with dolls. But the series is fantastic, and therefore deserves a place here. The story unfolds on a future Earth encountering aliens that look a lot like us. The aliens of course, are nothing but unfriendly, attacking every military means of Earth. So in the end, "Star Fleet" call upon the best of fighters and aircraft stylists to counter attack these mysterious enemy. 

As the cartoon resumes, a dosen other things happen, that also sets the good side as not so good either, and vise versa.
