We’ve already learned that Super Smash Bros on the Nintendo 3DS will contain a game mode called Smash Run. The mode sees players tackle numerous enemies from established Nintendo franchises. Speaking to YouTube channel GameXplain, Chris Niosi talks about other boss characters that are meant to show up in Smash Run. Among those discussed are Bonkers, Kraid of Metroid fame, a Kremling boss, and even the Great Reaper from Kid Icarus: Uprising. Gamenesia believe that the Kremling boss is Klubba, from Donkey Kong Country 2. You can watch the video above.
