Lucario

Lucario is the 448th Pokémon and is known as the Aura Pokémon. On January 18th, 2008 an updated video at Wii.com was released that people have interpretted to mean that Nintendo accidentally confirmed him, Ness, and Jigglypuff to appear in Super Smash Bros. Brawl. In the new Japanese trailer for the game on the time 4:20 and 4:21 images of stickers are shown, including Groudon, Claus, and Sonic. If paused on 4:20, immediately when Groudon is highlighted, the characters that the sticker can be attached to are shown as icons in the bottom right corner. It shows the icons of Pikachu, Pokemon Trainer, and what players have taken to be Lucario and Jigglypuff. Since the only trace of Lucario is on that video, his inclusion is still in heavy doubt. However as a result of the leak in Japan with a new character screen, it is becoming even more likely that C. Falcon, Jigglypuff, Ness, and Lucario are going to be SSBB.
