The impressively cosmic character roster integrated into the well-loved title "Super Smash Bros. 4" was laid out for fans in full detail. With a rich set of 40 playable characters at hand, fans believe it is still all the more expansive. And with the upcoming DLC for the game, it can be pushed to its limits.

A leaked "Super Smash Bros." video, although unconfirmed, has been an attention hub lately. Various media outlets and fans have feasted on the leaked video showing the character line-ups graced by Mewtwo, Waddle Dee and Wolf. However, a bulk of them instantaneously slammed the rather suspicious clip.

Nevertheless, the glorious return of the mighty Psychic Pokémon Mewtwo is indeed happening. In the Nintendo Direct for Smash Bros Wii U on Oct. 24, Mewtwo was introduced as a free content alongside a plethora of more SSB goodies. Mewtwo is still in development but its developer stated that spring 2015 is the mark date for his homecoming. The requirement to get this fan-favorite Pokémon is reportedly to own both Nintendo 3DS and Wii U versions of the game. However, Nintendo remains silent and fans hope of a possible Mewtwo appearance without a need to get both.

Mewtwo is just one of the wonders to look forward to in the "Super Smash Bros. 4" DLC. According to Flickering Myth, a Miiverse stage is set to emerge in the upcoming game. It is fashioned closely from the "Battlefield" stage with the exception of the real-life Miiverse posts dashing in the milieu. The stage will simply represent and depict the particular character selection in the game.

Also, thanks to the DLC, all produced stages offline will now be shared online, complete with replay footages. This is a gradual process though. As players go through the created stages, they will eventually acquire the ability to show all these to the online world.

And the most thrilling part perhaps, is the assimilation of tournaments in the game. This will grant players the chance to host 64-player competitions as well as participate in Nintendo's own match-up schemes. With this, gamers can double the "Super Smash Bros." fun by combating with pals and fellow gamers under totally modifiable rules.

The "Super Smash Bros." DLC is expected to be released in 2015. Gamespot also reported that the "Super Smash Bros. Wii U" will be released on Nov. 21 in the U.S. and Nov. 28 in Europe. That's a week earlier than planned.
