Every weekday, Masahiro Sakurai posts a screenshot of Super Smash Bros. for Wii U and Nintendo 3DS. These screenshots can be anything from revealing a veteran character or showing a new stage to Wii Fit Trainer lying down seductively or infamously Luigi adjusting his nose. Due to this, any day could be the day that your favorite character gets deconfirmed.
And yes, that means that any day could be the day that the Ridley Nuke strikes. Be careful, friends. Be careful.
