This year's WrestleMania is kicking off with the Fifth Annual THQ Superstar Challenge. The event will have 16 WWE superstars competing in WWE Smackdown vs Raw 2007 for the Xbox 360.

The winner of this single elimination tournament will be crowned King/Queen of THQ/JAKKS Pacific's WWE SmackDown vs. Raw 2007. Popular wrestlers of the WWE roster will be competing in the tournament including Batista, Mr. Kennedy, Carlito, Bobby Lashley, and other superstars.

Bob Aniello, senior vice president of worldwide marketing for THQ, said that the event "celebrates the hard work and dedication of WWE and its Superstars throughout the year". He added that "The WWE Superstars participate extensively in the making of our WWE video games, and with the success of WWE SmackDown vs. Raw 2007, it's great to see them come together to enjoy the finished product."

During the same night, the two finalists of THQ's first online WWE tournament will be competing in a championship match. The winner will be taking home two floor tickets to WrestleMania 23, a WWE Championship Belt, and additional prizes. After the event, recording artist Nonpoint will be performing live. Hopefully, they will play some of their songs from SmackDown vs. Raw 2007 such as "Bullet With A Name" and "Alive And Kicking".

The event will be held at the Gem Theatre in downtown Detroit on March 29. It will be open to the public with tickets being sold for US$ 17.50 at Ticketmaster.
