New boy group named 100% to debut in August

A boy group named 100% is set to debut in August 2012  under T.O.P. Media.  T.O.P. Media manages TEEN TOP, which would make TEEN TOP a label mate of 100%.

The current members include Rocky (~21 years old), a member of the duo Jumper which disappeared from K-pop shortly after its debut in 2009.   The other members are Minwoo (~27 years old), Jonghwan (~20 years old), Chanyong, Changbum, Hyukjin, and Sanghoon (all about 19 years old).

There is already a SBS MTV series that showcases T.O.P. Media's TEEN TOP and 100%.  You can watch the entire 50 minute episode under the cut (unfortunately, no English subs).
