Dwayne 'The Rock' Johnson is a former nine-time World champion (seven WWF Championship and two WCW Championship reigns) and is one of the most successful pro wrestlers outside of the ring. On March 12, 2007, The Rock made his most recent appearance on WWE, after a near three year absence when he appeared on RAW via pre-taped segment on the Titantron and correctly predicted that Bobby Lashley and Donald Trump would defeat Umaga and Vince McMahon at WrestleMania 23 in their 'Battle of the Billionaires' match.
