I think that she is one interesting character..
She will appear soon in two comics, Green Arrow and the Teen Titans.. Is time for create Emiko Appreciation.
This is a summary about her:
Emiko Queen(called previously Emiko Lacroix) was born to Robert Queen and Shado on Starfish Island. However, as a baby, she was kidnapped by her father's protégé-turned-enemy, Simon Lacroix, better known as Komodo. Lacroix would train Emiko for years with the Outsiders' Arrow clan, leading her to believe he was her father.
Years later, she knew the truth and she started to live with Oliver Queen(her halfbrother), helping Green Arrow in his adventures.. With the time she wanted to be Red Arrow, but her brother did not accept this despite she was one important member of Arrow family... However this changed when she was seriously injured saving his brother life, making him accept that she was the new RED ARROW..

Oliver Queen suggested her for Teen Titans.. But when she met Damian in TT comic, she rejected the offer.. However, after NO JUSTICE events, she joined the New Teen Titans in Teen Titans Special 1..
