Diddy Kong

"After all we did to get them back last time? Donkey Kong would go crazy if he lost his bananas again!"

- Diddy Kong

Diddy Kong is Donkey Kong's little buddy who has gone on countless adventures with him. Diddy is a creation of the British company, Rare Ltd.; however, he has a Nintendo logo on his trademarked red hat, probably because Nintendo owned Rare and the rights to the Donkey Kong franchise at the time.

The name "Diddy" is a slang word used in some parts of northern England for "small", as Diddy is. Diddy has gone on many adventures by himself occasionally with his girlfriend Dixie Kong, and has even starred in his own racing game for the Nintendo 64 and later for the Nintendo DS.

Concept and creation
During the development of Donkey Kong Country, the designers wanted the player to be capable of taking multiple hits, but they also aimed for the screen to be as "clutter-free" as possible, thereby forbidding the usage of an health bar. Having noted the "Big Mario to small Mario" system used in the Super Mario games, Rare created Diddy as a visual "extra hit". The design for the character was originally intended to be a redesign of Donkey Kong Jr., but Nintendo felt that their design was too different, and asked that Rare either include Junior with his original appearance or make the new design an entirely different character. Rare, feeling that the design fit the "updated" Donkey Kong universe that they were aiming to create, had decided to keep their design. During the process of naming the character, several names were suggested by Rare employees, including "Diet DK," "DK Lite" and "Titchy Kong". The name "Dinky Kong" was chosen, but was later changed to "Diddy" due to legal considerations, although the name would eventually be used as Kiddy Kong's Japanese name. .

Donkey Kong Country
Diddy Kong first appears in Donkey Kong Country, as the co-star of the game with Donkey Kong. Here, he is still Donkey Kong's apprentice and an "in-training video-game star". On one night, Diddy Kong is given the task of guarding Donkey Kong's Banana Hoard. However, the Kremling Krew attacks and defeats him, trapping him inside a barrel. After being released, he and Donkey Kong set off across Donkey Kong Island to save the Banana Hoard and drive off the Kremlings. At the end of their journey, Donkey Kong and Diddy Kong reach King K. Rool, the leader of the Kremlings, and by defeating him, the two win back Donkey Kong's Banana Hoard.

In this game, Donkey and Diddy Kong share the same basic abilities (jumping, running, cartwheeling, etc.). However, Diddy Kong is weaker than Donkey Kong, unable to jump on enemies such as Krushas or Klumps to defeat them, but DK can. Despite this flaw, Diddy is still faster than him and can jump higher than him. Diddy Kong also carries barrels in front of him, allowing him to protect himself from an enemy, but he cannot throw it as far as Donkey Kong.

Donkey Kong Country 2: Diddy's Kong Quest
In Donkey Kong Country 2: Diddy's Kong Quest, Diddy is the main hero. The Kremling Krew kidnaps Donkey Kong and sends him away to their own island, Crocodile Isle. K. Rool, who is now Kaptain K. Rool, threatens to permanently hold Donkey Kong prisoner unless he is given the Banana Hoard. Diddy refuses to give it up because he and Donkey Kong took plenty of effort recovering it in the previous game. Diddy and his girlfriend, Dixie, venture through Crocodile Isle and rescue Donkey Kong from Kaptain K. Rool. Near the end of Diddy's Kong Quest, while Donkey Kong is rescued by Diddy and Dixie Kong, Crocodile Isle sinks into the ocean.

Donkey Kong Country 3: Dixie Kong's Double Trouble!
Diddy Kong is captured in Donkey Kong Country 3: Dixie Kong's Double Trouble!, and Dixie Kong and Kiddy Kong must save him.

Dixie, worried about the two Kongs, decides to venture to the Northern Kremisphere to search for them with her baby cousin Kiddy Kong. After Dixie and Kiddy defeat Baron K. Roolenstein they discover that KAOS, K. Rool's stand-in leader for the Kremling Krew, contains Diddy and Donkey. It seems K. Rool has abducted Diddy and Donkey for the purpose of using their brain energy to power KAOS. After being rescued Diddy and Donkey goes back to Donkey Kong Island while Dixie and Kiddy defeat the Kremling Krew.

However, Diddy fails, and he is presumably shoved into a barrel. In it, he and Donkey Kong go on another quest to reclaim the Banana Hoard, which has been stolen by the Tiki Tak Tribe by hypnotizing the animals on the island. After defeating Tiki Tong, he and Donkey Kong get the Banana Hoard back from the Tiki Tak Tribe. Diddy can also be controlled in this game by a second Wii Remote, and his jetpack can be used.

Melee, he is mentioned in both games. Diddy Kong was revealed for Super Smash Bros. for Nintendo 3DS / Wii U on February 21st 2014, the day of the North American/European release of Donkey Kong Country: Tropical Freeze.

For the Super Smash Bros. series, Diddy is given a more realistic monkey voice, instead of the cartoonish voice he is commonly given in Mario series titles.

The Subspace Emissary
In the Jungle, Diddy Kong helps Donkey Kong recover bananas stolen from the Koopa Troop, only to have Bowser appear and attempt to use his Dark Cannon on the Kongs.

In Volleyball, Diddy Kong can give his full power shots an added curve, which is something that is typically seen with the Technical characters.

Fortune Street
Diddy Kong appears as a playable character in the Wii follow-up to Itadaki Street DS, Fortune Street. He is a Level D character, alongside Birdo, Donkey Kong, Slime and Yangus.

Other appearances
Diddy was to star in both Diddy Kong Pilot and Donkey Kong Racing as a main character and a sidekick, respectively, but these games were canceled before they could be released when Rare Ltd. moved to Microsoft.

In 1998, despite not yet being part of the Mario series, he was featured alongside Mario, Yoshi and Koopa Troopa in a Pez dispenser set. Diddy Kong also appears in Nintendo Monopoly, where he costs $260, and took the role of Ventnor Avenue.

Physical appearance
Diddy Kong shares several traits to a Spider Monkey. He has versatile feet, and a prehensile tail, which he uses most of the time to hold certain small items or also hang on objects. Diddy Kong's face is somehow similar to Donkey Kong; however, Diddy has big eyes and a less frowned space between the eyebrows, covered in fur, as opposed to DK's. His ears are a bit big, the same size of his eyes. Diddy's eyes are usually depicted as black, although Diddy Kong Racing reveals blue eyes. On the other hand, Super Smash Bros. Brawl gives him brown eyes.

Diddy's clothing consists of a red cap showing the logo of Nintendo on its front, and a red tank top, with yellow Stars on it (the details on his clothes were first introduced in Donkey Kong Country 2: Diddy's Kong Quest). In Donkey Kong Country, an alternate Diddy's clothing was a yellow tank top and a yellow cap. It appeared when two players wished to play independently. In Donkey Kong Country 2: Diddy's Kong Quest, Diddy Kong appears with another alternate costume as well. In the sequel, Diddy wears a blue costume. For the recent edition of Super Smash Bros. series, Diddy has a wider selection of alternate color costumes. In Mario Strikers Charged, Diddy wears armor, protecting him against hazards set in the game. He wears a pair of wristbands, shoulder-pads, and a cuirasse over his tank top to protect his chest. The armor is mainly yellow, but it turns to purple in case that his opponents wear a similar color scheme. Later in Donkey Kong Country Returns, when the Super Guide mode is activated and Super Kong breaks a DK Barrel open, Super Diddy Kong appears. Super Diddy Kong has white fur, a white cap, and a blue tank top.

Powers and Abilities
In almost every appearance he makes, Diddy Kong has been shown to be very quick and nimble to offset Donkey Kong's great strength. As a result, Diddy has more trouble defeating larger enemies. In many games he has appeared, such as in Donkey Kong Country and Donkey Kong 64, he is able to use his cartwheel to attack opponents but also to jump farther in Donkey Kong Country. Diddy is shown to have a strong skull; he has a special dashing ability in Donkey Kong 64 called Chimpy Charge where he ram into switches, walls, and gongs with a head-first charge and in Donkey Kong Country Returns, after defeating Tiki Tong, he brings the moon down with just his head.

While teamed up with Dixie Kong during the events of Donkey Kong Country 2, Diddy is able to pick up his partner and throw her to high areas or enemies. He can also throw her at collectibles that float above pits.

In some games, Diddy Kong can also use his Jetpack to fly to hard-to-reach areas. However, in Donkey Kong 64, this Jetpack is only given to him after entering one of Cranky's Kong Barrels, and it can only be used in certain areas. During the time Diddy Kong uses his Jetpack, he is also equipped with Peanut Popguns, which allow him to defeat or stun distant enemies and activate switches. During Donkey Kong Country Returns, Diddy can use his Jetpack in order to carry Donkey Kong over pits. It's revealed in Donkey Kong Country 2: Diddy's Kong Quest, that Diddy has a prehensile tail due to the fact he can hang onto hooks with it. Additionally, in Donkey Kong 64 he is able to use his tail to attack enemies or use it as a spring to reach higher areas. In Super Smash Bros. Brawl, he is able to combine his Jetpack and Peanut Popgun for his final smash. He can also perform Wild Moves in Donkey Kong Barrel Blast.

In Mario Superstar Baseball, Diddy Kong, with his good running stat, also possess the ability to climb on walls and catch balls that are otherwise fair. He also has Super Catch ensuring that he does not fumble any routine fly balls. His pitches and batting involve curving the ball in the shape of a banana. This ability is also present in Mario Power Tennis. In Mario Striker Charged, Diddy displays some natural abilities such as summoning a beam of light that subdue his opponents into the sky and psychic abilities during his Mega Strike. In Mario Sport Mix, his special move is throwing a banana like a boomerang which stuns opponents after being hit by it.

Diddy Kong is capable of juggling, which he does in Donkey Kong Country 2 if he does not move for a while. Also, his artwork for Mario Super Sluggers portrays him juggling three baseballs. Just like Dixie in Donkey Kong Country 2, he is also capable of playing an electric guitar in Donkey Kong 64, which he uses to solve puzzles and destroy surrounding enemies.

Donkey Kong
Donkey Kong is Diddy Kong's best friend and idol. Diddy would not appear to be related to Donkey Kong since they are different species, but he has been called Donkey Kong's nephew on occasion, such as in the English version of Super Smash Bros. or once on Rare's website; however, the Japanese version of Super Smash Bros. did not call him DK's nephew, Leigh Loveday himself uses uncertain language, and the Donkey Kong 64 instruction booklet only considers him "Donkey's little nephew wannabe." The idea was soon dropped, and the usual story returned to them just being close friends.

Cranky Kong
Cranky Kong considers himself to be a "grandpappy" of sorts to Diddy (as well as Dixie), and while he complains about Diddy receiving a starring role in Donkey Kong Country 2: Diddy's Kong Quest while he was stuck in a gloomy shed, he also calls him a true video game hero and comments that he must take after himself and Donkey.

Dixie Kong
Dixie Kong has accompanied her boyfriend Diddy Kong on a few adventures and sports outings, including Diddy Kong Racing DS, in which Donkey Kong did not appear. Their romantic relationship is not often touched upon in the games themselves.

Official profiles and statistics
Diddy is usually introduced as DK's buddy in his official bios, with Dixie being mentioned occasionally as well. He is typically described as being small and agile, and his stats in most spinoffs accordingly make him a lightweight and/or speed character.
