Helen of Troy

Helen of Troy was a figure from Greek mythology who was famed for her beauty. She was the daughter of Zeus. Her kidnapping by Paris resulted in the Trojan War. For this reason, she was called "the face that launched a thousand ships."

After meeting Yeoman Theresa Ross of the USS Enterprise (NCC-1701) in 2267, Trelaneas "Fair Helen" and requested that she make him "immortal with a kiss." However, Captain James T. Kirk prevented Trelane from kissing her. 

Helen was studied by the 23rd century historian Alexander Lazarus, who created an android, with the psi-clone, and imbued it with Alexander's personality and history. This android, like other androids of Lazarus, created a city on Gamma Alpha V. She was likely destroyed in the explosion of Gamma Alpha V on Stardate 10:26.3.
