X-Men Classics is the name of two different series of 6-inch X-Men action figures by Toy Biz. The first line was released in 2004 and consisted of comic accurate sculpts and paint applications. The line went on hiatus after 1 wave. The line was revamped in 2005 and lasted 3 waves. It featured several new sculpts of both completely original costumes and previously unproduced costumes with repaints of existing figures scattered throughout. The revamped line also featured 4 new vehicles and a repainted Sentinel from Toy Biz's 1990s 5-inch X-Men line.
