There’s been a lot of discussion recently regarding future DLC characters for Super Smash Bros. for 3DS and Wii U. Currently, Nintendo is accepting fan suggestions to get a better idea of which characters would be most wanted as DLC. One thing we don’t know is exactly how many fighters are planned to eventually be included. However, it appears as though the official Super Smash Bros. website is suggesting that there will be six characters in total.
If you go to the page of any of the Smash characters, you may notice a scrolling roster at the bottom of the page. Going to the end of this list, we see Mewtwo and then five faint, blank squares. This seems to indicate that after Mewtwo, there is room for five more characters. Nintendo confirmed during last week’s Direct that Lucas will be appearing in June, so one of those spaces belongs to him. So if this suggestion is to be believed, that means there will still be four more to come in the following months.
If there’s anyone in particular you want to see, make sure you cast your vote!
