The Helirin (ヘリリン, Heririn) is a machine with long rotor blades that appears in the game Kuru Kuru Kururin. It appears as a trophy in Super Smash Bros. Melee and an Assist Trophy in Super Smash Bros. Brawl.
 In Super Smash Bros. Melee
The Helirin appears as a trophy in Melee. Due to translation issues, it was mistakenly named 'Heririn'.
 Trophy description
Kururin sets off in his specialized helicopter to rescue his siblings who have lost their way somewhere among ten worlds. The helicopter is fitted with an enormous blade, which propels the machine forward by slowly rotating. The mazes that Kururin must navigate are narrow and filled with all kinds of strange obstacles.
 In Super Smash Bros. Brawl
In Brawl, the Helirin appears as an Assist Trophy. When summoned, the Helirin will fly to a certain part of the stage. The characters can stand on the Helirin and use it as a moving platform. It stays out for a rather short length of time, rotating slowly all the while. Presumably, the craft is being controlled by Kururin himself.
 Assist Trophy origin
Helirin first appeared Kuru Kuru Kururin. In Kuru Kuru Kururin, the player controls a thin helicopter that has slow moving propellers. Each level involves maneuvering through a maze without hitting the propellers against a wall. If the propellers hits the wall, it gets damaged. When the propeller hits the wall three times, the game is over. The Helirin also appears in the Gamecube game Kururin Squash and is the first game where the Helirin is rendered in 3D. In Brawl, the Helirin appears as an Assist Trophy and looks similar to its design from Kururin Squash. Also, the Helirin doesn't get damaged when it hits a wall or the ground, which is contrary to what happens in the Kururin games.
 Trophy description
A unique helicopter that flies with long, slowly rotating wings. If the wings strike walls or obstacles, the Helirin takes damage and loses hearts. The wings normally spin clockwise, but the rotation can be reversed by touching springs. There are many areas that require this technique. The Helirin can be customized by picking up and using a variety of items.
