Ethan Locken was a genetically engineered Human and a former member of Section 31. He was a great admirer of Khan Noonien Singh. Locken, he was in his thirties or forties in 2376, and had short cut red hair that had receded into a widow's peak. He was neither tall nor physically imposing, but his eyes were a dark brown or almost black color. Locken was, by any account, a brilliant scientist. He used his genetically enhanced abilities to work on medical advances in long-term statis, cloning, DNA resequencing, memory engram transfer, and other similar pursuits.
