So, we've got a kid Aussie as our favorite sardonic superheroine. And she really is a kid; I can't help but think they dad that for dramatic purposes. They may use her age to highlight the despair of her fate as Trigon's agent, or to draw comedy from her comparative maturity, particularly if Beast Boy is roughly the same age. Personally, I hope they copy the cartoon for her power set. Telekinesis and teleportation are clearly defined and practical powers.
