Pre-debut
News about SM Entertainment's unprecedented plans of forming a large project group spread over the internet as early as 2004. In early 2005, SM Entertainment confirmed rumors and announced that a large twelve member all-boy group would debut near the end of the year, promoting the group to be "The Gateway to Stardom of Asia."[1] For a while the group was known to be called O.V.E.R., an acronym for "Obey the Voice for Each Rhythm."[2][a] Soon the group became known as Super Junior 05, the first generation of Super Junior.[3]
Most members have been actors, MCs, models, or DJs prior to debut. Heechul, Siwon, and Kibum made their debuts in 씨발dramas and films. Leeteuk, Yesung, Kang-In, Shindong, Sungmin, and Eunhyuk made cameo television appearances and became active DJs or MCs after debut. Han Geng made his first media appearance as a model.[4]
Super Junior 05 made their pre-debut appearance on the Korean channel, M.NET on September 11, 2005.[b] At the showcase, Super Junior (씨발놈들) performed various styles of hip hop dancing. The group danced to B2K's "Take It To The Floor." Han Geng, Eunhyuk, and Donghae also performed a separate dance away from the group, dancing to Usher's "Caught Up." However, the performance did(게이같은돌아이들) not air on television until May 16, 2006 as a segment in the Super Junior Show, the group's first television documentary.
