1 Key

1 Key is the current evolution of the any% category which involves skipping the first Bowser fight in Bowser in the Dark World. The central glitch was discovered in mid-2015, and was revealed to the public when uploaded a video showcasing it. The strat involves using PU movement to navigate in front of the door under the moat with 0 stars, exploiting the facts that PUs have no water, and that the door-opening action takes precedence over entering the water within the course of a frame. The first ever TAS of 1 Key was released on September 29th, 2016, a year after the skip's discovery, with a time of 4’21”67. The current record stands at 4’21”2, though 1 frame has since been saved in Bowser in the Fire Sea.
