According to Oliver Queen, Red Dart along with with the other Hunters were a trio of assassins who apparently disappeared in the 1950s and were even feared by the League of Assassins. This slightly proves that Red Dart may have some form of longevity.
Red Dart is first seen where she and the Hunters successfully steal a "super-battery" from an A.R.G.U.S. facility. Later, she and Kodiak, along with Ricardo Diaz, are then pursued by A.R.G.U.S. agents on a train and fight them, proving their fearsome capabilities. However, John Diggle was able to escape with the battery. A week later, the Hunters assist Diaz in breaking into C.D.C. and stealing vials containing a drug that enhances strength and supposedly grants an immunity to drugs. During this, they encounter Rene Ramirez and F.B.I. agent Samandra Watson and they fight and overpower them. Although they were successful, Silencer was captured, leaving Red Dart slightly worried about her teammate. She later witnessed Diaz injecting himself with the serum and was slightly horrified.
Weeks later, Red Dart, along with the other Hunters, assisted Diaz in his attempt to blow up Star City. Upon witnessing his capture, and knowing that their payment wasn't exactly worth it, they made their escape from Team Arrow. Red Dart was never seen again after Ricardo Diaz and Dante's deaths.
