"Twins (Knock Out)" is the debut single by Super Junior, when they were still known as Super Junior 05, which was released online as a digital single on 8 November 2005 and later on the group's first studio album, Twins on 5 December 2005.

Before the single was released for download, Super Junior 05 made their debut as a group on SBS's Popular Songs on November 6, 2005, performing "Twins (Knock Out)".

Super Junior 05's cover version kept the original song's hip-hop influence but incorporated heavier bass elements and quicker rap, forming the song into a rap rock piece. The promotional title of the song, "Twins", was added to the song's title to mark the change in lyrics from the original song. The Korean lyrics, written by Yoo Young-jin, speaks of self-deception and the indecisive aspects of mind, contrasting the feelings between a man towards love and how he has to decide whether or not he should continue to love or fight with sticking to his own destiny.^{[citation needed]}

The music video was filmed in a dance studio. A majority of the scenes are simply dancing footage, where the members are surrounded by fire and also the contrast, blue sky.^{[citation needed]}

Similar to the lyrics and music style of the song, the choreography displayed for the music video contains quick and tough body movements. The snatching movements of the wrist, elbow, and any other joint on the arms and legs are richly used in a form of a robot. Other hip hop movements, such as popping and locking, are also commonly used. Unlike Super Junior's other dances, sliding, waving, and other smooth movements are rarely used in the dance choreography. It is said that the movements of a flying eagle was an inspiration to the choreography, such as in the beginning of the dance and in the dance bridge towards the middle of the song, where their dance forms takes shape of an eagle.^{[citation needed]}
