Frank Chen (died March 2013) was a prominent and wealthy businessman in Star City. He was also the father of Amanda Chen and an old friend of the Queen family. Frank had very close ties to The Undertaking, and was influential in its success. He was later killed by Malcolm Merlyn.
At some point of his life, Frank Chen had a daughter named Amanda Chen.
Amanda was beaten and nearly lost her life in the Glades by getting raped. This led Frank to join Malcolm's crusade to get revenge on the people responsible for assaulting and nearly killing her.
In March 2013, Frank was killed by Malcolm Merlyn, after being revealed but also framed by Moira Queen as sole conspirator instead of a co-conspirator, for the assassination attempt on Malcolm's life.
