Yi Suchong

"This is Dr. Yi Suchong, M.D. He studied ADAM for so long when we were trying to containing ADAM, and keeping it away from the outside world, far away from Rapture, the underwater city. We fear that ADAM will dominate the world if we do not stop it now. I pray that ADAM will be eradicated soon."

--Su Ji-Hoon, Saving Elizabeth

Dr. Yi Suchong M.D. was a leading medical researcher in Rapture studying ADAM and its uses to create Plasmids and alter brain function, as well as creating the Little Sisters and Big Daddies. Usually referring to himself in the third person, Suchong was an egomaniacal opportunist, using even tragic events such as war to his own benefit. He conformed perfectly to Rapture's objectivist society and worked simply for the highest bidder.

Life on the Surface
The life of Dr. Yi Suchong began as the son of a lowly house servant in rural Korea. But, when World War II occurred, he seized opportunity from the serious upheaval all across Asia.

During World War II, Suchong was in Korea at the time of the Japanese occupation, and was accused of selling opium to the Japanese to fund his experiments.

Most of Suchong's years before Rapture are clouded, but he mentions in one of his audio diaries that "Japanese kill every man in my city." Suchong was spared during the slaughter because he supplied the Japanese troops with opium. A Chinese newspaper reported Suchong's disappearance in December 1946 as he fled to avoid being hunted down by the chinese government for collaboration with the enemy.

Career in Rapture
In Rapture, Suchong set up an independent research firm, Suchong Institute and Laboratories, which contracted out to Ryan Industries and Sinclair Solutions. In 1951, Suchong grew dissatisfied with the inconsistent funding provided by Andrew Ryan and began covertly working for Fontaine Futuristics
