Cosmic Showdown

Cosmic Showdown was the titular game show that appeared in the film Sailor Stars: The Game Show of Doom. It is run and hosted by the Demon Quiz.

The show focuses on several teams from different worlds competing in a life-threatening game show, where there could only be one winning team. It was discontinued when Quiz was defeated and its time slot was replaced by Sailor Moon merchandise commercials.

The show probably premiered in 2011.

Dunk Bowl
In this event, contestants must dunk their team’s balls into other teams’ buckets while trying to dodge a small but dangerous beast that guards the teams’ final buckets, which are located inside a dark cave. In the film, the Sailor Senshi team (Usagi, Ami, Minako, Rei, Makoto and Chibiusa) came out last in the game, with Usagi barely escaping from the vicious cave beast, which she destroyed using the Moon Spiral Heart Attack. As last in the standings, they are forced to eliminate one member from the team, and Chibiusa is chosen to be eliminated.

Taste Test
In this event, the Sailor Senshi team versed the Antenna life forms to try to eat something without getting poisoned, whether it is a food from Earth or another planet. In the film, an Antenna being (nicknamed “George” by Quiz) choked on a cake, while Usagi won an important point for the team after biting on an alien carrot. Due to a negotiation with Quiz, the Senshi team got Chibiusa back after winning the round.

The food items featured on the wheel in the 2017 games are:
 * Alien carrot
 * Cake
 * Dark Fruit
 * Moon Pie
 * Juice bottle
 * Japanese curry
 * Unknown alien dish
 * Unknown alien dish
 * Unknown alien dish
 * Unknown alien drink

Obstacle Course
In this event, the Sailor Senshi team raced against the Magnavators across a dangerous obstacle course. The course spans across a large gap where contestants must jump across floating plates, followed by jumping over a tall wall, crossing a river of boiling lava using a giant crystal as a bridge and going through a dangerous metal door with grabber claws.

Trivia Showdown
In this event, the Senshi team and the Pyrite team first had to bash a gong and the one who bashed it first receives a trivia question. Luckily, Setsuna from the Outer Senshi team was able to answer the question correctly which caused the Sailor Senshi team to win the Cosmic Showdown.

Discontinuation
After the Senshi Team won the grand prize, a spaceship, Quiz suddenly announced her plan to blow up the other planets in the Solar System, which causes Usagi to tell everyone that Quiz is a Demon and the Sailor Senshi are here to end Quiz’s show forever. Chibiusa and the Outer Senshi arrive at the UFO to confront Quiz.

The Senshi Team engage Quiz in a great battle in the UFO, which culminated in Chibiusa throwing a pie onto Quiz’s face to weaken the Demon. In the battle, the Senshi received a report from Professor Tomoe that Quiz gets her energy from a giant battery inside the UFO. In response, Chibiusa uses her Pink Sugar Heart Attack to destroy the battery, causing the UFO to crash land on the Moon and weaken Quiz. The Senshi Team finally defeat Quiz and turn her back into a quiz book.

Shortly after Quiz's death, the show was replaced by Sailor Moonmerchandise infomercials.
