He was a member of the Anoaʻi wrestling family and frequently worked as a part of a tag team – variously named The Island Boyz, the Samoan Gangstas, and 3-Minute Warning – with his cousin Matt Anoaʻi. During Fatu's first stint with WWE, he was known as Jamal and Matt was billed as Rosey. In late 2005, Fatu returned to WWE. Repackaged under the ring name Umaga, Fatu went undefeated for many months on WWE's Raw brand throughout much of 2006, before suffering his first defeat under the Umaga name in January 2007. The following month, he won the WWE Intercontinental Championship for the first time, and won it for the second time in July 2007.
