Enter King Bowser is the first episode of the series, it introduces some of the main characters, such as Mario and Bowser. It is scheduled for an April 2017 release.
It's a race between our heroes and their rivals as they race their way through Mario Circuit, but the race is interrupted by an unknown figure. Who is this person? And what does old face Bowser want? Meanwhile, Mecha Sonic arrives in the Mushroom Kingdom...
The Sockop at the start of the episode, Kuribo, is first seen during the events of Bowser's Inside Story, where his name is revealed.
Mario Circuit is a racetrack found in Mario Kart: Super Circuit and Mario Kart 8.
This episode plays homage to standard Mario Kart games, such as having 8 racers, Mario Kart items and a track exclusively from the Mario Kart series.
This episode marks the first time Mario Kart items are used.
Bowser calls Lakilester a "Nimbus Freak", this is a referrence to Nimbus Land, a location from Super Mario RPG, which appears later in the series.
The episode title is based on the title of Dragon Ball episode, "Enter King Piccolo".
Bowser mentions how Mario swung him around by his tail in Super Mario 64.
This episode marks the debut of attacks than do not originate from the Mario, Sonic or Kirby series, this is seen when Bowser uses Seismic Toss on Mario, doing the attack the same way Ash's Charizard does in the Pokémon anime, and when Mario does Captain Falcon's Falcon Punch, which originated from Super Smash Bros. 64.
Bowser makes a direct reference to the Hunger Games series by saying "Looks like the odds really were in my favor!", the original tagline was "May the odds be ever in your favor.".
The two Toads are the same ones that appear in the New Super Mario Bros. games.
The two Toads believe the capsule Sonic and Shadow are inside belongs to E.Gadd, who does not appear until episode 4.
The scene where Mario uses the Blue Shell is based on a scene from the YouTube video Racist Mario.
