The 'Steve in Smash' meme refers to the explosive reaction following the October 2020 announcement that Steve from Minecraft would be joining Super Smash Bros. Ultimate as a DLC fighter. The announcement was so massive that it famously caused Twitter to crash momentarily, cementing the moment in internet history. The meme typically utilizes the 'Steve Joins the Battle' splash screen or screenshots of his unique gameplay mechanics, like building blocks or eating steak mid-fight. It is used to express shock at unexpected crossovers, celebrate the cultural dominance of Minecraft, or satirize the competitive Smash community's reaction to the blocky character's inclusion.
