Yesterday's Super Smash Bros. Ultimate-centric Nintendo Direct stream started off on something of a dark note: we saw a terrified Luigi running through a castle in his classic Luigi's Mansion attire trying to avoid snakes, creepy statues, and mummies, all while armed only with a plunger for safety. Eventually, he ran straight into the grim reaper itself. With one fell swoop, the reaper swung its scythe and knocked Luigi's soul from his body.Of course, this was all a clever set-up to announce that Simon and Ritcher Belmont from the Castlevania series would be joining the already robust cast of Super Smash Bros. Ultimate when it lands on Switch later this year. The classic vampire hunters will be bringing their traditional brand of combat to the title with a wealth of well-known weaponry including axes, crosses, holy water and their iconic whips.However, supposedly killing off one of Nintendo's most popular characters didn't go down too well with fans of the series, so Nintendo has stepped in to confirm that Luigi did, in fact, survive his tangle with the grim reaper. There were no more details given, however. Instead, Nintendo's VS Twitter account in the UK simply posted a tweet on the topic saying "Luigi is okay."Aside from the fate of Luigi being confirmed, the Belmonts will be joined by Donkey Kong Country's King K. Rool when Super Smash Bros. Ultimate arrives on Nintendo Switch on December 7 this year. It will also be available in a fantastic limited edition bundle featuring a GameCube controller and adapter in Europe.
