Diamond (Japanese: ダイヤモンド Diamond), also known as Dia (Japanese: ダイヤ Dia), is a main character in the manga series Pokémon Adventures.


Diamond's one man skit

Diamond is the stooge (boke) of the comedy duo, with his childhood friend Pearl playing the straight man. Despite appearing seemingly dopey and slow-witted when performing his role, he is actually very perceptive. His name is often shortened to Dia, but is also called by his full name, Diamond, by Pearl when the latter is unusually serious.

Diamond is often apathetic and rarely not seen eating - even in dire situations, as was the case when he had a feast with his Pokémon while aboard a Team Galactic airship that was headed straight to their HQ. He shares these traits with his Pokémon, especially so with his Munchlax. While not fat, he is much less active and energetic when compared to Pearl or Platinum, as seen when Platinum mused that every morning since the trio began traveling together, Diamond would perpetually end up being the last to get up. However, he is always serious when it comes to food and is an expert at cooking Poffins. He also displays an ability to analyze the situation at hand - when something strikes him as illogical, he will attempt to make sense out of it. Diamond has a somewhat natural instinct to judge how a Pokémon feels and can be quite observant when something arouses his interest. He is driven by emotion, thus his association with Mesprit. For his skills, he is given the title of "Empathizer" (感じる者 Empathizer).

Diamond has a large amount of respect for Pearl, and despite the latter's tendency to berate him aggressively, the two are as close as brothers. Diamond also has a not-so-small crush on Platinum, which he developed when they first met.

Diamond has changed a lot from the beginning of his journey with Pearl and Platinum. He was convinced by Pearl after the incident at Veilstone City to set aside their dream of becoming great comedians to protect Platinum until she finishes her journey. On Iron Island, he also received training from Riley in order to further his battling skills, which were lacking when compared to Pearl's and Platinum's.

Younger Diamond and Pearl

Diamond grew up in Twinleaf Town with his mother where he enjoyed his favorite anime, Proteam Omega. His best friend was his neighbor Pearl, who he partnered up with to make a Comedy Pair after seeing two famous comedians at a show.

Diamond & Pearl arc

Diamond in the seventh chapter

Diamond first appeared at the New Generation Funny Grand Prix in Jubilife City, where he, along with Pearl, was awarded the Judges' Special Merit Prize. Upon leaving the Grand Prix with their prize, Diamond and Pearl bumped into Professor Rowan and his assistant, Mr. Berlitz, causing them to accidentally switch envelopes and, unknowingly, receive the mission to guard Platinum Berlitz on her journey to the top of Mt. Coronet, although they believed they were on a reality show and Platinum was the host.

In Oreburgh City, Platinum decided to challenge Gyms, and Diamond and Pearl helped her train, which helped build trust within the young trio. At the Valley Windworks, they met up with Mars for the first time and defeated her with Diamond's emotion and kindness. After many different trials and crises together, they finally reached Mt. Coronet, but they soon discovered that the cavern they entered would not lead to the summit, and therefore had to continue their journey on to the eastern side of Sinnoh.

In Hearthome City, Platinum decided to enter a Pokémon Super Contest. While Pearl helped Platinum practice, Diamond began cooking Poffins. When Platinum was about to quit the Contest due to her being attacked by the other participants, Diamond cheered her up with a piece of pie, which allowed her to continue and win.

Afterward, the trio was attacked by Platinum's true bodyguards, Paka and Uji, who believed that Diamond and Pearl where kidnappers who had taken Platinum for ransom. Thankfully, they were saved by Fantina, who took them to the Lost Tower. Once Fantina deemed it safe for them to leave, the trio went to the Solaceon Ruins, where they saved some Unown before heading back out on their journey.

In Veilstone City, Diamond and Pearl met up with Paka and Uji for real and had their first true battle with Team Galactic. During this battle, Diamond's Tru and Chimler both evolved and Platinum's true identity was revealed to the two boys by Paka and Uji. However, before her real bodyguards had a chance to meet and explain things to the girl, they were banished into another dimension by Saturn. Once this happened, Diamond confessed to Pearl that he knew Platinum wasn't a reality TV host from the beginning, but he had kept it to himself because the misunderstanding was the thing that created and held together their friendship. The two then took an oath that they would protect her and keep their real identities a secret.

Later, following a separation from Pearl at Lake Valor, an adventure in the Great Marsh and Platinum's Gym challenge in Pastoria City, they met up with Cynthia at the Pokémon Mansion, and she helped them clear the group of Psyduck that were blocking Route 210. They encountered Cyrus again in Celestic Town when the man broke into the ruins that held Sinnoh's legend of the three lakes. After the showdown with the man, in which Diamond and Pearl had a huge argument that had nearly cost them the victory, the trio ended up in Hearthome once again and Platinum challenged Fantina, who turned out to be the Gym Leader of the Hearthome Gym.

After gaining a victory, the trio learned of Mr. Berlitz and that Professor Rowan had disappeared. In order to find them, the trio went to Canalave City, where they mistook Byron as Mr. Berlitz and Professor Rowan's kidnapper. During the battle between the young trio and Byron, Diamond befriended Byron's Shieldon. After realizing the whole thing was a misunderstanding, Platinum finally learned of Diamond and Pearl's true identity, and was completely horrified by the shocking news. However, after a horrible night full of nightmares, she decided to keep the boys as her companions and they resumed their journey with the new goal to stop Team Galactic's evil plans.

Diamond's training on Iron Island

The trio was then split up to defend the three lakes of Sinnoh and Diamond was assigned to go to Lake Verity. However, Byron didn't believe that Diamond was a strong enough battler and made him go through training with Riley on Iron Island. During this, he learned to overcome his weakness in speed.

Soon, Diamond was back in Jubilife City, where he saved the President of the Pokétch Company from wild Lickitung, which evolved into a Lickilicky during the battle and joined Diamond's team. Afterwards, he arrived in Sandgem Town accidentally found himself in the Berlitz's Mansion and was mistaken as a thief by Platinum's butler, Sebastian, but this was quickly taken care of and explained. Before resuming his quest towards Lake Verity, he fought off a swarm of Yanmega that was sent by Team Galactic to attack Professor Rowan's Science Lab.

Diamond then made one last detour and returned home to find some winter clothes that his mom bought him, finding a note left by his mom telling him that she was heading to Lake Verity to get some Berries. Upon reading that, Diamond realized that his mother was in danger and rushes out of his house to the nearby lake, where he finds his mother being held hostage by Mars.

Diamond and his Mom fought off Mars and Diamond went airborne on Drifblim. However, after Mesprit was awakened, he managed to sneak onto the Team Galactic Air Shuttle and found himself back in Veilstone City. There, he infiltrated the headquarters of Team Galactic by disguising himself as a Team Galactic Grunt and fought the mysterious Advanced level Grunt. He later was forced to sacrifice his Pokédex in order to free Mesprit but was reunited with Pearl and Platinum soon after.

Regigigas appearing to Diamond

The newly reunited trio then regrouped with Cynthia and headed to the Spear Pillar, where Diamond and Pearl split up with Platinum and Cynthia, and time and space begins to distort. The two boys begin to fight Dialga and Palkia but are quickly stopped by the two dragons' abilities to manipulate the fabric of reality. After Cyrus ambushes them, a giant hole appears in the sky that starts sucking everyone on the Spear Pillar into it. Diamond attempts to dive into the hole and close it from the inside to save everyone; before he can do it, he is saved by a Regigigas.

Regigigas and Diamond decide to team up to battle Dialga and Palkia, successfully preventing them from moving and causing any more destruction. Cyrus quickly knocks Diamond off Regigigas and questions how a boy who knows nothing of Time and Space could understand why he's trying to create a new world. Diamond then shows that he does, in fact, understand what Cyrus meant and verbally states what he believes Time and Space is. Diamond's words cause an imbalance in the control that Cyrus has over Dialga and Palkia and he hastily attempts to try to regain control, hitting Diamond with the Red Chain in the process. Platinum realizes that with only one Red Chain, controlling Dialga and Palkia will be almost impossible and at certain times, the power controlling one dragon will shift into another's favor, and she commands Diamond and Pearl to attack the two dragons. The attack manages to successfully break the Red Chain and the two Dragon-type Pokémon from Cyrus's control. Dialga and Palkia then use their powers to distort Cyrus in a sphere of light and he falls to the ground unconscious.

They all celebrate their victory and decide to go home while taking their friends and Cyrus to the hospital. As they leave, Diamond notices someone watching them and the Canalave Gym Leader, Byron, emerges from the ground and takes the machine he was holding. However, this causes the hole in the sky that was created by Dialga and Palkia's fighting to have mysterious black tentacles to shoot out and grab Cyrus, Dialga, and Palkia, who are all dragged into it. The old man introduces himself as Charon and makes an attempt to escape, but Diamond's Kit grabs a small notebook while he runs away.

It is later revealed that the notebook that Kit had stolen from Charon was a book with information on Legendary Pokémon. Joined by the Sinnoh Pokémon Association Chairman and Dr. Footstep, Diamond and Pearl use the notebook that was deciphered by the Sinnoh Elite Four and search for the Legendary and Rare Pokémon of Sinnoh.

Their first stop is to return to the Old Chateau where they find the Pokémon that had attacked them in their last visit, Rotom. The two are attacked by Rotom and its many different forms. Eventually, Diamond manages to bond with Rotom and befriends it; Rotom then joins their group.

Soon after, Diamond and Pearl hear a large noise and runs to the location where it came from. Upon arriving, they find a giant dragon Pokémon called Giratina going on a rampage and destroying Eterna City. Immediately, Reg erupts from its Poké Ball to battle Giratina. Soon after, Charon appears and reveals that intends to kill Diamond and Pearl in his plan to capture the Legendary and Rare Pokémon of Sinnoh.

Diamond and Reg face off Charon's Heatran while Pearl goes off to battle Giratina alone. With Reg's powerful Crush Grip, they manage to nearly defeat Heatran. When Charon forces Giratina to use Shadow Force, Diamond pushes Pearl out of the way of the attack, but gets hit by it in the process and is knocked unconscious. Much to Pearl's distress, he tries to wake Diamond up, but to no avail.

Seeing that its Trainer has died, Reg appears to leave, but soon returns with Rotom's appliances so that it can attack Charon in its rage. Together, Reg and Rotom force Charon and Giratina to retreat back into the Distortion World. Soon after, the Sinnoh Chairman and Dr. Footstep return to the scene after hearing all of the commotion. As soon as they return, Diamond's body suddenly begins to distort and disappears.

Later, Diamond awakens in another world, confused at his current surroundings. He quickly figures out that he is in the Distortion World, having touched it three times prior. There, he encounters Cyrus, and asks him if he knows how to beat Giratina.

Cyrus takes him to an area where Giratina had trapped Dialga and Palkia in a mineral after it dragged them into the Distortion World. Together, they free Dialga and Palkia from their prison. They ride the two dragons back to where Pearl and Platinum's groups were and reunites with Paka and Uji. After Diamond and Pearl return Paka and Uji's sunglasses, the Advanced level Grunt returns the stolen Pokédexes back to their proper owners.

As the battle between the Legendary Pokémon continues getting more and more chaotic, everyone begins to gather together. When Charon decides to escape, Diamond, Pearl, and Platinum each take a different Legendary Pokémon to fly and chase after him before he can trap everyone inside the Distortion World. They fly and eventually make it outside to Sunyshore City, where Charon is finished off by a surprise attack from Cynthia.

Charon tries to escape like he did at the Spear Pillar, only to be cornered by Diamond, Pearl, and Platinum. Although defeated, Charon refuses to give up, and uses his machine to try and make Diamond, Pearl, and Platinum's Pokémon attack each other. The machine is quickly destroyed by a toy of Proteam Omega, which is revealed to be possessed by Rotom.

With Charon defeated, everyone who was left behind in the Distortion World emerges from it safe and unharmed. Cyrus disbands Team Galactic, but thanks the three before leaving with Mars, Saturn, and Jupiter. Giratina tries to attack one last time, but is stopped by Volkner and Flint and is driven back into the Distortion World by Dialga and Palkia, this time without any desire for revenge.

Charon is arrested by Looker, who gives Diamond a Pokémon Egg given to him from the Fiore Region before leaving to his next mission in Unova. Having emerged from everything victorious, the three give each other a fist bump. Later, Platinum watches as the sole audience member as Diamond and Pearl gives her a comedy routine, which she hadn't seen in a while.

Sometime later, at the Solaceon Day-Care Center, Diamond plays with Phione, a Pokémon that hatched from an Egg. Pearl berates him for playing with it when they are supposed to be training it, which Diamond responds by having the Pokémon use Heart Swap. The owners of the Day-Care recall of a Trainer that hatched a Pokémon with a similar personality to his in the Johto region.

Omega Ruby & Alpha Sapphire arc

Younger Diamond appears as a cameo together with Pearl when Palmer talks with Brandon. The boys would like to go outside to practice their comedy routine but Palmer stops them due it being dangerous because of the asteroid threat.
