Roy Koopa

Roy Koopa (also known as Bully Koopa) is the third oldest of Bowser's eight children. From what has been revealed about Roy's personality, he is more brawn than brains, preferring brute force over thinking things through. Despite this gruff, tough-guy demeanor, Roy originally wore a pink shell, which may be a reference to the fact that some (jokingly) say pink is a manly color. He now wears a purple shell though. Roy also wears red sunglasses similar to his namesake, the legendary rock and roll musician, Roy Orbison.

Super Mario Bros. 3
In Super Mario Bros. 3 Roy was charged by Bowser with taking over Sky Land. Easily doing this with his airship and armies, Roy stole the wand of Sky Land's king and transformed him into either an Albatoss or a Duck with it, depending on which version of the game.

Adventuring through Sky Land, Mario managed to reach Roy's airship. Managing to pass all the traps on Roy's airship, Mario reached Roy's cabin, where he engaged the burly Koopaling in combat. In battle, Roy would leap at Mario and try to crush him with his ground-shaking stomps, Roy would also shoot energy blasts from his stolen wand. Despite his power, Roy was defeated by Mario.

Super Mario World
In Super Mario World Roy took over the Forest of Illusion when his father attacked Dinosaur Land. After fighting his way through the perplexing Forest of Illusion Mario reached Roy's castle and ventured his way to the Koopaling's chambers.

In this battle, Roy would utilize Morton's attack pattern by climbing-up the walls of his room and try to crush Mario by dropping down from his ceiling. Unlike the last battle, the walls of the arena would steadily close in, giving Mario less of an easy time to avoid the attacks. Mario managed to defeat the wall-crawling Koopaling by bashing him on the head repeatedly.

New Super Mario Bros. Wii
Roy, along with the rest of the Koopalings, appeared in the game New Super Mario Bros. Wii as a boss. He wears a purple shell instead of his pink shell from the past games. Unlike his past appearances, where he was the fifth Koopaling that the player had to fight, Roy appears in World 2 instead.

In the first fight, Roy's arena is similar to Larry's first arena except that it is filled with quicksand. Before battling Roy, he is shocked that Mario made it to him and roars at Mario. In battle, Roy will make jump and ground pound like a Sledge Bro.. If Mario doesn't jump when Roy lands on the ground, he'll be stunned by the shockwave, leaving him vulnerable. Roy's magic is pink in color and will hurt Mario if he comes in contact with it. In addition, his casting seems to be faster than Larry. Like most other bosses, three stomps on the head will defeat him. Roy will leave the fortress and flee to the castle at the end.

In the second fight, the arena is closed and there are no hazards. However, Kamek flies overhead and casts a spell on the arena, causing five huge Warp Pipes in different sizes to protrude from the ceiling. Roy will then jump into the Warp Pipe and start shuffling around. He'll then jump out of the pipe and make a huge shockwave, stunning Mario. Not only will Mario have to watch out for Roy's shockwaves, but he also has to be careful not to be crushed by the koopa from above. After 3 stomps, Roy is defeated and Mario claims the key that unlocks World 3.

Roy survived the battle, however, and was seen along with the other Koopalings getting Bowser back up, only to have Bowser's castle fall on top of all of them.

This is also the first game where the player faces Roy before facing Morton. Also, he is not the boss of a sky world (as he was in Super Mario Bros. 3), but rather a desert world (which Morton was the boss of in Super Mario Bros. 3).

Super Mario anime series
Roy, as well as his siblings were featured in the Super Mario Amada Series, a set of three Japanese OVAs. In the Mario retelling of the story "Momotaro", Roy and his siblings appear as minions of Bowser, aiding him in abducting Princess Toadstool. In "Shirayukihime (Snow White)" Roy also appears as a minion of Bowser once again, like his brothers and sister, Roy ends-up being beaten by Mario.

Cartoons
In The Adventures of Super Mario Bros. 3 and Super Mario World cartoon by DiC Entertainment Roy was renamed Bully Koopa. Bully, as his name would imply, constantly pummeled and pulled cruel-pranks on friend and foe alike. Out of all the Koopalings, Bully seemed to have the least amount of air-time in the DiC cartoons, only appearing occasionally, though he did have a major role in "Do the Koopa", "Recycled Koopa" and "The Yoshi Shuffle". He was also seen having a slightly major role in "Mush-Rumors". In the continuity of the cartoon series, Bully was regarded as the eldest Koopaling. Bully was given a Brooklyn accent in the DiC cartoons. The only other differences are he wore a collar and had only one spike in center of his shell.

Nintendo Comics System
Roy was also featured in the Nintendo Comics System. Here Roy's personality was similar to his "Bully Koopa" incarnation, but lacking the Brooklyn accent. The Nintendo Comics System issue "Bowser Knows Best" also revealed that Roy had a pet rabbit named Pookie, whom he would often abuse for his own amusement.

Super Mario Adventures
Roy also appeared in the Super Mario Adventures comic, where he aided Bowser in his plot to hypnotize and marry Princess Toadstool.

Mario is Missing!
Though absent from the NES version of Mario is Missing! Roy does appear in the PC and Super Nintendo version of the game. Following his family to Earth, Roy had planned on aiding them in their plot to melt Antarctica, thus flooding Earth.

Roy was eventually defeated again in the corridor of Bowser's fortress by Luigi, who had been searching for his kidnapped brother.

Yoshi's Safari
In Yoshi's Safari Roy appears as the boss of Float Castle I. Roy battles Mario and Yoshi in a large hot-air balloon equipped with six cannons. Despite having this mass amount of firepower, Roy was still defeated by Mario's Super Scope.

Hotel Mario
In Hotel Mario Roy is in charge of and the boss of Roy's HardBrick Hotel; a hotel with somewhat shoddy electrical wiring. Fought on Roy's Rowdy Rooftop, Roy uses the same attack pattern against Mario in this game as he did in Super Mario World; climbing-up the walls and trying to stomp Mario. Ultimately, Roy was once again beaten by Mario.

Mario & Luigi: Superstar Saga
After several years of absence in a Mario game, Roy made a return appearance in Mario & Luigi: Superstar Saga; during Bowletta's invasion of the Beanbean Kingdom, Roy acted as a guard in Bowser's Castle, which Bowletta had hijacked.

After making their way through Roy's puzzle filled room, Mario and Luigi approached the Koopaling, who fled at the sight of them. Leaving Roy's room, thinking the Koopaling had turned coward, Mario and Luigi were sneak attacked by the oversized Koopaling.

In this battle, Roy would attack by spitting fireballs, spinning in his shell, and stomping the ground, sending shockwaves at Mario and Luigi. Despite having the aid of a Time Bob-omb in battle, Roy was still defeated by the combined might of the Mario Brothers.

Super Princess Peach
Roy was originally going to appear in Super Princess Peach but was removed along with the rest of the Koopalings for reasons unknown. Interestingly enough, Roy's sprite has him wearing a green shell, and he had what looks like a light orange head.

Personality
Roy is depicted as typical bully who usually beats up people (or his siblings) for his own amusement. However he is seems quite fond of the color pink. He has a pink head, pink sunglasses, and a pink shell. This is most likely a reference to when people joke saying pink is a manly color. Bully Koopa had the exact same personality. It is also rumored he spends most of his time beating up his little brother, Iggy Koopa, though he was seen beating mostly Morton in the cartoons.

Physical Appearance
Roy is a muscular Koopa. He is always shown wearing a pair of red sunglasses, which obscures his eyes in the games, though in The Adventures of Super Mario Bros. 3 and the Super Mario World cartoon, his small eyes are visible through the lenses of his sunglasses. Like Wendy, he originally had a pink shell. However, in New Super Mario Bros. Wii, his shell is a shade of purple. He has a pink head, and is the only Koopaling to have one. His unused sprite for Super Princess Peach bears a green shell, and an orange head. Like most of the Koopalings he has visible fangs in the corners of his mouth; they are bigger than his siblings' fangs.

Bio from The Adventures of Super Mario Bros. 3 Writers Bible
''As long as you're smaller than he is, Bully will push you around. His favorite sport is stealing lunches from second-graders in wheelchairs. Bully is the most dangerous of the kids. The oldest, he would try to take over his dad's position as king, if his dad would stop being such a big bully and let him do it. Bully has a gang, but nobody will join it. He thinks he's totally cool, and loves fifties greaser music in Nintendo style.

Trivia
