Captain Falcon, Fire Emblem and male and female versions of Robin have been added to the characters list of Super Smash Bros 4, totaling 37 overall.

Nintendo announced on Monday that they will include these four characters.

Alternative outfits for Super Smash Bros 4 have been revealed: an all-white Samus costume and United States-themed Mario clothing were leaked, GameNGuide.com reports.

A Super Smash Bros 4 WWE 2K15 style trailer by madagascarsan has leaked, showing many of the Nintendo game's wishlist characters featured in a wresting version of the game.

At over 100 Best Buy locations, gamers were allowed to play the demo Nintendo presented at E3 2014 conference and fans made predictions for likely gameplay features.

Super Smash Bros 4, available on the Nintendo Wii U and 3DS, was made available for pre-release play on June 11 and 14.

Characters like Ike and Marth appeared together representing Fire Emblem in the roster, Gameranx reports.

"Ike's back to join Marth in representing Fire Emblem. There was a call from fans to bring characters from Fire Emblem Awakening (I mean, I wanted Marth Lucinda myself), but Ike is by no means a bad choice," the website writes.

"He seems set to be a power character with considerable range thanks to his sword, and he is definitely a fine addition to Super Smash Bros' roster. He's coming in to this game wearing his Radiant Dawn Threads, a little older, wiser, and not too shabby looking, based on the reactions I've seen."
