Super Smash Bros. for Nintendo 3DS is already out, so we know the full character roster, but Smash director Masahiro Sakurai is still hooking us up with reveal trailers for characters that are new to the series. Since Bowser Jr. wasn't given an official reveal trailer before the handheld game launched, that was rectified during today's Nintendo Direct. You can check out the awesome trailer for Bowser Jr. (and his Koopaling alternates!) by clicking above!
