Hello Kitty Roller Rescue (known as Hello Kitty Mission Rescue in Japan) is an Action-Adventure Video Game based off of the popular Hello Kitty franchise. It was released for the Nintendo GameCube, the PlayStation 2, the Xbox, and the PC.
Following his last, disastrous attempt at conquering a planet, the evil Emperor Block-O stumbles upon Earth and decides that this time, he will succeed. To that end, he quickly launches a massive, block-shaped army to invade Earth and kidnap Kitty's friends and family. Block-O's ultimate goal is to turn everyone on the planet into a cube-shaped being like himself.
Hello Kitty is not pleased. Armed with a magic wand and roller skates, she must rescue those who were captured and turn back the alien invasion. Once she rescues enough friends, they can help too, with each partner offering different combat abilities.
The game has a fair amount of unlockables, with character profiles, mission rankings, upgrading partners, a Sound Test, and rescuing everyone who was captured.
This game contains examples of:
- Alien Invasion
- And Your Reward Is Clothes: Doing well on missions can get Kitty new outfits.

- Crutch Character: Badtz-Maru helps out for the first stage only.
- Distressed Damsel/Distressed Dude: Block-O and his minions have captured all of Kitty's friends and family. Kitty herself becomes one in the New Game+.

- The Dragon: Block-O's field commander, who is fought in the penultimate mission.
- Drop the Hammer: One unlockable weapon is a mallet.
- Early-Bird Boss: While the tank boss doesn't take much to go down, you have little health at that point in the game.

- Gatling Good: Watermelon guns act like machine guns, and the final boss has a twin set of guns to shoot you with.
- General Failure: Block-O hasn't conquered anything before setting his sights on Earth.
- Glass Cannon: The crocodile helper, Pochi has the best attack, but is very fragile.

- Holiday Mode: There are special Loading Screen pictures for holidays, as well as Hello Kitty's birthday.
- Implacable Man: Block-O's final weapon is this. It's impossible to defeat it; you have to stall it until Keroppi can finish it off with a Wave-Motion Gun.
- It's a Wonderful Failure: Failing to stop the giant robot in the final mission results in a Downer Ending where Block-O succeeds and the Earth and all of its inhabitants are turned into a cube.

- Mr. Exposition: Keroppi, via Kitty's computer.
- Never Recycle Your Schemes: Averted in the New Game+, with Block-O doing everything exactly the same as before with two additions to the plan: His robot, and the other bosses are even stronger, and Kitty is kidnapped.
