"100%" Released: March 21, 2012 (Promotional single)
100% Ver. is the fourth EP released by South Koreaboy bandMBLAQ. The album was released online on January 10, 2012. The online pre-orders started on January 10, 2012. It was recently revealed that 100% Ver. had over 40,000 pre-orders. The album consists of five new tracks, and the title track This Is War is a Dance Ballad with Orchestra Music. On March 21, the EP was re-released under the name "BLAQ% Ver.". The song "100%" was supposed to be the title track of the re-release, but the group will not promote the song to focus on solo activities.
On January 5, MBLAQ released their teaser of "This is War" on their official YouTube channel, J.Tune Camp. The video reveals the 5 members in their ensemble scene, and some small snippets of the full music video. The teaser ends with the members standing center stage with a string orchestra gathered on either side of them, shooting at the audience and finishes with a violent blood splatter that reveals their lead single's name, "전쟁이야 (This is War)". On the same day, the first concept photo was also released by J.Tune Camp. The directors jokingly stated that there was a particular member, Mir, who wanted to shave his hair bald, however they took fans' opinions in to consideration and only let the member go as far as a mohawk.
Not much has been said by the members about their secondary single, "낙서 (Scribble)". The group members only said, "You will be able to know about this song by listening to it rather than by us explaining about it". "Scribble" was released on music portal websites on January 3, 2012. When "Scribble" was released, it reached number one on Soribada and Bugs Music, number three on Mnet's Music chart, and number four on Cyworld Music. "Scribble" was also promoted along with their lead single, "전쟁이야 (This is War)", multiple times on stage as their second single from their 100% Ver..
100% Ver. was released on the same day as the music video, containing a total of five songs: "Run", "전쟁이야 (This is War)", "낙서 (Scribble)", "아찔한 그녀 (She's Breathtaking)", and "Hello My Ex" respectively.
