Dear Greg,

My father and I recently started watching "Young Justice" and are enjoying it greatly.

I have a few questions:

1. I love the realistic depiction of powers; I do, however, have some questions about the Martians. I am a bit confused as to why Ms. Martian doesn't telepathically blast all her enemies at various points in the show--or why she doesn't telekinetically repel or control them all, similarly to how Parasite controlled Superboy. When fighting Slade on the Manta submarine, could she not, regardless of whether or not it would be advantageous, not force him to fall asleep or smash him repeatedly against a wall?
2. On a similar note, how do Rocket's powers exactly work? Could she defeat nearly anyone in a fight by enclosing them in a bubble (Superman, Batman, etc)? Obviously, the trick is to combat her with multiple opponents.
3. Is there a character who is considered the most central to the show; and why was the cast expanded so much in subsequent seasons?

Please continue the good work.

James
