Luigi

Luigi is Mario's younger but taller and thinner brother. He appears in most Mario games as Player 2's character, but has starred in Luigi's Mansion and Mario is Missing! as the main character. He has also appeared in the Mario Kart series, the Super Smash Bros. series, and the Mario Party series.

In Super Mario Bros. 2 it was learned that Luigi can actually jump higher than Mario. However, he's also slower and has worse traction. Some games including Super Mario Galaxy and Super Smash Bros. Brawl supported the fact that Luigi is faster and can jump higher than Mario but his strength and power are slightly weaker.

While the brothers were initially considered heroes in the same level of fame, it wasn't too long until Mario started taking the spotlight and Luigi passing as a more secondary character. However, it was later learned that Luigi is not quite as brave as his brother, and usually prefers Mario to do all the hard work.

It is also thought that Waluigi is Luigi's arch enemy as Wario is to Mario. The reason for this is because Waluigi has an upside down L and Wario has upside down M. L stands for Luigi and M stands for Mario and as Mario and Wario are rivals it is only fair to say that Luigi and Waluigi are rivals too.

History
Luigi's first game was in Mario Bros., an arcade game that featured Mario, and his brother, which is Luigi. The game took place in underground pipes. In these pipes, bugs and other animals have gotten inside of them and Mario and Luigi have to get them out.

After Mario Bros, Nintendo came out with Super Mario Bros., in this game, Luigi was almost identical to Mario, other than green overalls, though he could do everything that Mario could do, in the exact same way. The sequel to Super Mario Bros., was the Japan only Super Mario Bros. 2, in this game, Luigi could jump much higher but couldn't run faster than Mario. Some levels were only beatable with Luigi.

In the sequel, Super Mario Bros. 3, Luigi was once again the exact same as Mario, just with a few changes in color. The same happened with Super Mario World, though in Super Mario All-Stars, Luigi had a different sprite change.

After Super Mario Bros. 3 and Super Mario World, Nintendo went on to create spin-offs such as Super Mario Kart staring Mario characters such as Luigi. In the games, he was usually equal in stats to Mario, but some times he was lighter.

During the Nintendo 64 era, Luigi didn't star in any platforms, although he was in many spin-offs. This was quickly changed with the GameCube's launch when they forgot all about Mario and made Luigi the star of Luigi's Mansion for the new console. In the game, Luigi wins a new mansion in a contest he didn't even enter. Once he arrives, he finds out that Mario has been taken by King Boo and put into a painting. Now Luigi will have to use many new gadgets to go and save him. Luigi is a playable character in many more spin-offs such as Super Mario Strikers and its sequel, Mario Strikers Charged. Luigi is a supporting character in Super Mario Galaxy, but he can only help Mario after Mario saves him from a galaxy filled with Boos. After that, Luigi will get Power Stars Mario couldn't get, but he'll have to be rescued first, again. Once you collect 120 Stars, you'll be able to play as Luigi. Luigi is also a playable character in Mario Kart Wii.

Appearance
Luigi is Mario's younger brother. With that said, it's obvious that they would look the same. Unlike Mario's red clothes, Luigi wears a green undershirt, and dark blue overalls. He is taller than Mario, and has a different style of mustache and sideburns. He also wears a green hat that has a L on it.

Super Mario 64 hoax
For years people thought that Luigi was a playable character in Super Mario 64. Even though the game was already released and still no sign of Luigi, people still believed that he was in the game somewhere hidden away. It was once thought that the pedestal on the statue had something to do with unlocking Luigi, as some thought it said "L is Real 2041". It is currently known that the game does not include Luigi what so ever. However, some fans have went as far as to hack the game then change Mario's image into Luigi's, which also got fans to believe he was included once more.

Fans were pleased to find that Nintendo included him in the Super Mario 64 remake Super Mario 64 DS for the Nintendo DS, and as a playable character in Super Mario Galaxy after finding all 120 stars and defeating Bowser (with Mario) soon afterwards.
