1. Given what we were doing, which doubled as a nod to Teen Titans Go!, it worked for us to equate Beast Boy with Beast Boy, Chief with Robin, Elasti-Girl with Starfire, Robotman with Cyborg, and Negative Woman with Raven. Using Negative Man wouldn't have been as much fun for us - or for Tara Strong, who played Raven and Negative Woman.

2. Her powers are basically the same as Negative Man and Negative Woman's are in the comics. But we reserve the right to do our YJ twist on those powers if and when we have the opportunity to go into more detail on the character.

3. No spoilers.
