As stated earlier, the Naratu kids are basically just ninjas with energy blasts. The Teen Titans can counter these abilities with general easy.

Starfire alone could take down the whole Naratu team; with her years of experiance mastering several alien martial arts (and a few from earth) she can outclass and out manuvere this small group of upstarts in hand to hand combat. Also, I should mention Starfire has her own brand of powerful energy blasts that could rival a kamehameha

(Yes, I understand DBZ is not affiliated with Naratu. It's just a comparison.) As I was saying, starfire alone could take Naratu on.

The assistance of Superman's clone, a boy trained by the world's greatest detective, an Amazonian, a Cyborg, a shapeshifter, and a boy who can run fater than the speed of light and through time is not necessarily needed, they are really just sweetening the pot.
ololz, some people are crazy.
