Larry Koopa

Larry Koopa (also known as Cheatsy Koopa) is the seventh oldest of Bowser's eight children, and is the youngest of the seven Koopalings. As proved by Mario & Luigi: Superstar Saga, Larry loves to play tennis and has blue hair like Ludwig Von Koopa. Larry is seemingly best known to have a large blue mohawk which he, unlike his brother Ludwig, brushes and cleans. He has 4 visible fangs on the top corners of both sides of his mouth. However in New Super Mario Bros. Wii, he only has 2.

Super Mario Bros. 3
In Larry's first appearance, Super Mario Bros. 3, he was the first Koopaling to be battled. He had stolen the magic wand from the king of Grass Land and turned him into an animal. After Mario had gone through all of the airship's cannons, he battled Larry in his cabin. In this battle, Larry would jump around and shoot magic blasts from his stolen magic wand. He would need to be jumped on three times to be deafeted. Mario got back the wand, and the king was returned to normal, and thanked him for returning him to his original state. Larry also has white hair instead of blue.

Super Mario World
Larry's second appearance was in the last world of Super Mario World, the Valley of Bowser. In battle, he utilized his brother Iggy's attack pattern. He would sit on top of a tilting platform on top of lava and was immune to all of Mario's attacks. However, unlike Iggy, Larry's platform had 3 Lava Bubbles that jumped up and down. He could also throw more than one ball at one time. Larry would need to be jumped on until he fell off his platform. After the battle, Mario kicked away his castle (literally), and gained access to Bowser's Castle.

New Super Mario Bros. Wii
Larry makes his 3D-rendering-debut in New Super Mario Bros. Wii, alongside the rest of his siblings. Larry has been revealed to be a boss at the end of one of the fortresses, which is reminiscent of Super Mario Bros. 3 in this appearance he seems to have lost two of his fangs. Additionally, he has a blue shell similar to the color of his hair. He also as a blue star on the side of his head.

Yoshi's Safari
In Yoshi's Safari, Larry is the boss of Crescent Coast. Larry rides in a sun-like submarine that has a purple face and has a blue nose. Mario had to shoot at the nose to get it to open up and expose Larry. He will then zoom around the screen while Mario continued to shot at it. Eventually the submarine will break and Larry will whole a white flag while he floats up to the surface.

The Adventures of Super Mario Bros. 3
In The Adventures of Super Mario Bros. 3 and Super Mario World cartoons, he was named Cheatsy Koopa and was usually scheming up Bowser's latest plan, sometimes in conjunction with Kooky. A very common animation goof regarding Cheatsy was that his green head was often colored orange, the same color as the rest of his body. One particular shot in the episode "The Beauty of Kootie" even had his head mistakenly colored purple.

Super Mario World television series
In the Super Mario World series, Cheatsy's hair was changed to a lighter green color and drawn a tad thicker, most likely to resemble his appearance in the game.

There are several physical differences between Larry and Cheatsy: Larry's hair is pointed upwards but Cheatsy's hair was flatter and much more untamed; Cheatsy was almost always seen squinting and was given an overbite. He appears the most of all the Koopalings. Cheatsy was voiced by James Rankin. Additionally, in the continuity of the cartoons, Hip and Hop were the youngest Koopalings, not Cheatsy.

Nintendo Comics System
Larry often appeared in Nintendo Comics System comics, published by Valiant. Unlike his siblings and his father, he didn't speak English (whether he was unable to or didn't by choice was not revealed). Instead, he spoke in pictures, which was only understood by Lemmy.

Hotel Mario
The last appearance of Larry for several years was in the obscure Hotel Mario. He was found and battled in Larry's Chillton Hotel with the words "Larry's Cave Hotel" and "This mine is mine" written on the entrance. In battle, Larry would attack by using bombs as bowling balls. Like the previous battles, he was eventually defeated.

Mario & Luigi: Superstar Saga
After several years of absence, Larry reappeared in Mario & Luigi: Superstar Saga after his older sister Wendy was defeated. Before battle, Larry would trap Luigi in a barrel and shoot fireballs at him. To engage Luigi would need to stand in front of the Bob-omb to bounce them back, who would bounce them back with his tennis racket and would need to be hit with it. In battle, he would shoot fireballs and bounce them back with his tennis racket. He is also aided with a Time Bob-omb. In the end, he was defeated and once again disappeared.

Super Paper Mario
Surprisingly, Larry is mentioned in Super Paper Mario as the star of a game on Francis's "To get list": Larry Koopa: Zombie Heartbreaker. It is presumably a horror/survival/romance themed game.

Personality
Like the other Koopalings, not much of Larry's personality has been revealed. What has been revealed is he is interested in sports because he used bombs as bowling balls in Hotel Mario and he was revealed to be a master of tennis, but has not appeared in any Mario sports games. Also it has been revealed from The Adventures of the Super Mario Bros 3 cartoons that he likes listening to music, as shown in the episode "Never Koop a Koopa", where he is seen listening to the original Mario 'underground' music on his red headphones.

Bio from The Adventures of Super Mario Bros. 3 Writers Bible
''He loves to tie people up and then challenge them to a foot race. In reform school, he copied so many test papers, he got writer's claw. His hobby is counterfeiting Gold Coins, and he does such a great job of it, that Koopa has put him in charge of the Kastle Koopa treasury, where he happily spends every day cheating his brother and sister Koopalings on their allowances. When Koopa wants to be sneaky and devious, he calls on Cheatsy.''
