An avid gamer of “Super Smash Bros 4” who has been exploring and mining the 3DS version’s data recently discovered that there are five character slots available after Mewtwo, who is the first Super Smash Bros 4 DLC fighter.
The empty character slots are currently labeled “Mario” as a placeholder. This discovery may have revealed Nintendo’s plans to add even more playable fighters to the game.
Of the five slots, the first one is already known because it is going to Lucas, the second DLC fighter announced by Nintendo. However, the four slots still remain a mystery. Linking up the report about Ryu and Roy, it seems likely that these two characters will fill up the two slots, leaving the two other slots still a mystery.
It is also likely that the remaining two slots will go to those who receive the most number of votes from the Super Smash Bros Fighter Ballot that Nintendo opened just recently.
