Character Overview:
Diamond, nicknamed Dia, is one of the two male protagonists in the DP series along with Pearl. Slow and dopey, he plays the role of the funny man in the Manzai standing comedy which he and Pearl practice. He usually adopts a happy-go-lucky attitude and follows Pearl's lead and decisions, but actually has his own opinions, especially when it comes to matters that stir up his emotions. This is a reflection of the virtue he represents: emotion, making him the most associated with Mesprit of the Sinnoh lake trio, the emotion Pokemon. In contrast to Pearl, Dia's character is relaxed and carefree, and according to Pearl, has never ever broken out in a rage, except the one clash he had with Pearl at Celestic. His gentle nature is interestingly opposite to the diamond, and is more comparable to the pearl, which has an ultimate smoothness.
Dia is a big fan of the animation series 'Proteinman Omega', and is an expert on it. He is always seen eating snacks, and often uses food as jokes in his Manzai verses. Dia believes that good food can make a person happy, and personally made a cream pie to cheer Lady Berlitz up during her Super Contest challenge. He seems to have a talent in Poffin making, and managed to create a combination deemed difficult to mix by the Super Contest judge, Dexter. Dia was not particularly skilled or keen in battling at the beginning, although his luck and unorthodox whit usually saved the day. This changed when he decided to interrupt Team Galactic's evil schemes pertaining to the Sinnoh lake trio, and started to act more proactively to better his battling skills. Despite his apparent lack of ability in fighting, he is in truth extremely clever and given time, he is always able to figure out a way to solve a problem by his close observation of things.
As childhood neighbours, Dia grew up with Pearl, and the two share a very close bond with each other. Although Pearl often appears to be abusive in his endless hollering and smacking, Dia knows that Pearl actually cares for him a lot, and he in turn cherishes this friendship very much. The two had a fall out at Celestic Town however, when Dia disagreed with Pearl's choice of turning away from Cyrus's evil plans, and voiced out his need to follow his own emotions. His determination eventually moved Pearl, who complemented his actions with willpower. The boys reconciled afterwards, and Pearl suggested Dia give a try at One-Shot-Gag, the ultimate weapon of a comedian. By accident, Dia developed one that involved placing one Pokeball on each eye, standing on one foot while the other is bent backwards, and his hands touching at the base of the palms in front of his chest with his fingers opened up to the sides, all the while reciting the line 'I'm perfectly okeeay~'. Unfortunately, Fantina seemed to be the only person this gag managed to amuse.
Upon seeing Platinum for the first time, Dia was captured by the elegance she exuded, and is believed to be infatuated with her. This was also what made him knew right from the start that she was a true lady but not a tour guide. Yet, he chose to keep the secret to himself since the mutual misunderstanding was what formed and maintained their companionship, and he knew their group would fall apart once the truth was revealed. After Pearl learnt of the real situation and heard his reasoning, he also opted to keep Platinum in the dark about it. Dia's shyness held him back from being too obvious about his infatuation for Platinum, and only shows his care through his determination to keep her protected. Before knowing Platinum's real name, he addresses her as 'The Lady'.
Dia's design is based on the male protagonist of the fourth generation Pokemon titles, Pokemon Diamond and Pearl. Apart from his slightly lazier looking eyes, he is almost identical to his game counterpart. His items are mostly blue in colour, including his Pokedex as well as his Poketch. When the trio headed for separate ways, Pearl gave Dia the Manzai Scriptbook and changed it to a Battle Diary.
Dia has sported the most number of different attires any protagonist had, which included a black suit with top hat worn during the Super Contest, a chef's outfit for Poffin making, a colland-like attire at the Great Marsh, a clown's do as the campaign boy of the Poketch, one that resembled an Arabian King given to him by Sebastian at the Berlitz's Mansion, and also the Team Galactic grunt outfit when Dia snuck into the TG Headquarters. Upon returning home at Twinleaf, Dia found a new jacket his Mom bought him for the cold weather, which was from his game counterpart in the Platinum game. However, this jacket was just temporarily seen during the DP series, and Dia only started wearing it in the Platinum series where the rest of his outfit also matches the Platinum design of his game counterpart. Dia's eyes are of a dark shade of blue.
Dia's journey began when he and Pearl attended the New Generation Funny Grand Prix at Jubilife City, and was rewarded with the Judges' Special Merit Prize. However, a collision with Prof. Rowan accidentally swapped the envelopes they were holding, and the two boys ended up receiving the notice to Platinum's bodyguards, who were supposed to escort her to the summit of Mt. Coronet. Believing that they were on a reality show, Pearl deemed Platinum their tour guide and began their long voyage across Sinnoh.
Upon arrival at Oreburgh, Platinum decided to take on gym challenges, and Dia and Pearl started having training sessions with her. Trust began to build up among the young trainers as the trio went through crisis after crisis together. They encountered Mars of Team Galactic at the Valley Windworks, and later met up with Cynthia at Eterna, who personally taught them about Pokemon battling. When they finally reached Mt. Coronet, they discovered that the cavern they have entered would not lead to the summit, and thus continued their journey on the eastern side of Sinnoh. However, while inside the cavern, they were ambushed by Cyrus, who decided to punish them for disturbing the peace of the sacred mountain.
After taking part in the Super Contest in Hearthome, they were caught up by Platinum's real bodyguards at Veilstone, and also had their first direct battle with Team Galactic. It was only then that Platinum's real identity was revealed, but before the bodyguards had a chance to meet and explain things to the girl, they were banished into another dimension by Saturn. At this point, Dia finally confessed to Pearl that he knew Platinum wasn't a tour guide right from the start, and kept it to himself since the misunderstanding was the thing that started and maintained their companionship.
Later, following another turmoil at Lake Valor and Platinum's gym challenge at Pastoria, they met up with Cynthia again at the Pokemon Mansion, who helped them clear the pack of Psyducks blocking Route 210. After meeting Cynthia's Grandma, they encountered Cyrus once again at Celestic Town when the man broke into the ruins which contained Sinnoh's legend of the three lakes. Surviving the deadly showdown, the trio ended up in Hearthome again where Platinum challenged Fantina, after which they learnt of the shocking news about Sir Berlitz's disappearance.
At Canalave City, Platinum finally learnt of Dia and Pearl's true identity, and was completely distraught by the shocking news. After a fitful night of nightmares though, she decided to keep the boys as her companions and resumed their journey under the new goal to thwart Team Galactic's evil plans. At this point, the trio split up to protect the three lakes, and Dia was assigned Lake Verity. Unlike his two companions though, Byron made him go through a brief training session with Riley on Iron Island first, during which he learnt to overcome his weakness in speed. Later, back at Jubilife City, Dia helped the President of the Poketch Company solve a crisis caused by a wild Lickitung, and afterwards accidentally stumbled into the Berlitz's Mansion, where he was mistook as a thief by Sebastian. He then fended off a swarm of Yanmegas sent by Team Galactic at Prof. Rowan's Science Lab, and took a quick trip home to Twinleaf before resuming his quest at Lake Verity.
Unfortunately, Dia discovered that his mother, Johanna, has gone off to Lake Verity in search of Berries for food ingredients, and she became a hostage to Mars when Dia found her. Although Johanna managed to free herself, Dia failed in his attempt to protect the lake guardian, Mesprit, from being captured Team Galactic after the Galactic Bomb simultaneously woke the three pixies. Dia snuck into Team Galactic's air-shuttle and followed them all the way back to their headquarters in Veilstone City, where he disguised himself as a TG grunt and found the pixies at the science lab. There, he was confronted by the cloaked senior grunt who had a big interest in the Pokedex, and when Pearl and Platinum arrived later, the three sacrificed their Pokedexes in order to distract the cloaked grunt, freeing Mesprit, Azelf and Uxie in the process.
Afterwards, Cynthia gathered Dia, Pearl and Platinum and together they headed to the final battleground, the Spear Pillar on the summit of Mt. Coronet. Using Moo, a Mamoswine given to him by Platinum, Dia tried to subdue the legendary deities Dialga and Palkia, but was easily overwhelmed. When the energy portal created by two dragons threatened to suck everything in, Dia attempted to sacrifice himself by closing the portal on the other side, but Regigigas, a legendary Pokemon who secretly entered Platinum's bagpack, showed itself at that moment and helped the trio hold down Dialga and Palkia. After a direct confrontation from Cyrus, in which Dia challenged Cyrus's definition of 'time' and 'space', the trio borrowed hints from the ancient scripture carried by Cynthia and successfully snapped Dialga and Palkia back into sense by utilizing their duality nature. Yet, when it seemed like the crisis was finally over, a shadowy creature emerged from the energy portal and dragged Dialga, Palkia and Cyrus in, foreshadowing a new challenge and adventure for Dia, Pearl and Platinum.
During the events at the Spear Pillar, Dia managed to snatch a memobook from Charon which depicted the Sinnoh region rare and legendary Pokemon. Therefore, while Platinum headed towards the Battle Zone to seek information on the Distortion World, Dia and Pearl went on a journey to investigate and protect them from Charon, one of which being the plasma creature they encountered at the Old Chateau in the Eterna Forest before, a Pokemon named Rotom. Rotom played all sort of tricks on the boys with its various formes on their re-encounter, but Dia eventually figured out that it was just trying to show off its skills to them and got it to join them.
Before Dia and Pearl left Eterna, they came face to face with the serpentine creature that abducted Dialga, Palkia and Cyrus at the Spear Pillar, which is actually the ruler of the Distortion World, Giratina, having just barged into the real world dimension through a portal. Charon appeared with Heatran in an attempt to control Giratina, and Regigigas, Ghee, who has refused to leave its Pokeball since the Spear Pillar incident emerged to fight again. Unfortunately, while Dia was sheltering Pearl from Giratina's Shadow Force, he got struck and was presumed dead as his body vanished into thin air. However, he later awoke inside the Distortion World, and encountered Cyrus, who seemed to have changed his views about the world since his defeat.
Together with Cyrus, Dia freed Dialga and Palkia from their restraints, and joined everyone else who were already fighting Charon, Heatran, Darkrai and Giratina. Darkrai's sleep-inducing moves managed to hypnotize the other legendaries, but Shaymin reawakened them with Worry Seed. The gratitude Pokemon then tried to stop Giratina from going through a portal again but to no avail. Fortunately, Cynthia awaited outside and struck the ghost dragon down. As Dia, Pearl and Platinum cornered Charon, the TG Commander still intended to fight back with his signalling device that controls Pokemon, but Rotom possessed Dia's Proteinman Omega Robot and destroyed the machine, allowing Looker to arrest the man. As the legendaries went their separate ways, some returning to their original realm and some remaining with their trainers, Cyrus bid farewell to the Sinnoh Dex Holders after making the decision to officially disband Team Galactic.
