MBLAQ took part in a recording of KBS 2TV's 'Yoo Hee Yeol's Sketchbook' and revealed who they wanted to work with for a sub-unit. However, this was not limited to just MBLAQ members very much like how Toheart combined INFINITE's Woohyun and SHINee's Key.
For this fantasy sub-unit, G.O chose 2AM's Seulong, Seung Ho chose his schoolmate and senior B2ST's Junhyung, Mir chose g.o.d as he was a fan of the group since his youth, Thunder chose Big Bang's G-Dragon, and Lee Joon chose ZE:A's Kwanghee.
Lee Joon said, "Because there are a lot of members in ZE:A, Kwanghee complains that he gets too little parts. I understand his feelings, too. If we were to promote together, we could sing as much as we want."
Thunder also talked about promoting as a unit with his sister, 2NE1's Dara. He said, "My mother sincerely wants this, but it's hard in reality because our companies are different. However, I think it's possible to have Dara feature."
