The iconic character Sonic The Hedgehog will make his debut in the one of most anticipated games for Nintendo Wii,  Super Smash Bros. Brawl.

In their joint announcement, SEGA Europe and Nintendo Of Europe said Sonic joins a varied roster of characters, from Mario to Link to Zero Suite Samus and they also unveiled a trailer in which Sonic goes SuperSonic. Though, the character line-up is not finalized, so there could be other surprises.

Nintendo’s Super Smash Bros. series has been a firm favourite since the first title launched in 1999 on the Nintendo 64, and since the launch of Super Smash Bros. Melee for Nintendo GameCube, it has since gone on to have millions of fans worldwide.

Also SEGA and Nintendo announced that in the forthcoming Super Smash Bros. Brawl, players will for the first time be able to complete in online multiplayer battles for up to four players.

Super Smash Bros. Brawl will contain a new mode in which players can select their favourite character before embarking on an adventure to conquer giant bosses from the Nintendo Universe.

"Its amazing that after all these years we get to see these two much loved characters compete against each other in another fantastic title. Bringing Mario and Sonic together again underlines the continuing partnerships between Nintendo and SEGA, and produces another industry first for our two companies," said Mike Hayes, President and COO of SEGA Europe.

Mario & Sonic at the Olympic Games will be the first title to feature both iconic gaming mascots, Mario and Sonic and it will be released for Wii and Nintendo DS on November 23

The bad news for those who are waiting for Super Smash Bros. Brawl is that its Japanese launch has been delayed to January 2008 and in the US the game is now TBD (To Be Determined).
