There are several groups under this moniker.
- One was an alias used by The Outside Agency. They chose this project name because of Eye-D's love for the Marvel Comics title of the same name. Only one record was ever released under this alias because the two decided to move on to different labels after a disagreement with Coolman Records.
- One is a tribute band for Stephen Oulman's Tot Lot Band after hearing SOTLB's first album defective in Cedar Falls, Iowa, USA. They released a tribute album Defector.
- X-Factor is a 5 member Malaysian boyband and the first boyband formed by KRU Records. They debuted in 1999 after being trained for a year. The band disbanded in 2003.
