Black Canary, from Birds of Prey #81, by Gail SimoneThe Twelve Brothers in Silk, 12 martial artists named after the signs of the Chinese Zodiac, first appeared in the employ of Mister Tan, a Singaporean drug lord.
Mister Tan realized that he had been set up after agreeing to the terms that Black Canary stipulated, and in an attempt to avoid being ruined, he arranged for a real mob group to buy his drug shipment.
The Twelve Brothers accompanied the shipment to protect it, and met Black Canary and a group of fighters in America.
Black Canary's team consisted of Wildcat, Richard Dragon, Green Arrow II (Connor Hawke), Savant, Creote, Huntress, and herself.
Before the fight could end in one side's clear defeat, however, Black Canary signaled her teammate Lady Blackhawk to attack the drug shipment, destroying it.
They value honor highly, and Black Canary both exploited this and was careful to respect it — they would do anything to avoid "losing face", but to dishonor them would mean making a powerful enemy for life.
