Calem is a young boy who was born in Hoenn, and lived there for the first 18 years of his life. He decided to remain in school for all of his teenage life, opposed to starting his adventure at age 10. He planned to go on an adventure in Hoenn once he finished, however, his family decided to move just as he was going to do so, leading him to move to Kalos with them. When they had settled in Vaniville Town, he decided to go on his adventure.
Calem first appeared in Welcome to Kalos! A New Adventure Awaits! when he met Lexi after being informed of her arrival by Professor Sycamore. He and Shauna brought her to Aquacorde Town where all three of them received a Pokédex and their starter Pokémon alongside other kids Tierno and Trevor, in which he received a Froakie. They all joined together to head through Santalune Forest, in which Tierno and Trevor had gotten lost. Despite going back to help them, Calem's cocky nature resulted in them all getting in further danger, until Lexi saved them all. After venturing through the forest and saying bye to Tierno and Trevor, Calem headed to Santalune City with Lexi and Shauna. While there, Calem battled in a tag battle with Lexi against sisters: journalist Alexa and Santalune CityGym LeaderViola. Calem and Lexi won after Alexa threw the match, which ultimately led to Lexi and Viola's Gym battle. When Calem decided to battle Viola, she handed him a Gym Badge anyway after their tag battle, ultimately giving Calem his first Gym badge.
Calem joined Lexi on a long-time basis on her journey after deciding that he can learn to be more humble and become a better Trainer while with her. After the group entered Parterre Way, Calem wanted to capture a Pokémon that stayed by his side outside of its Pokéball like Lexi's Helioptile and Fennekin; which ultimately led to the capture of Skiddo.
As time progressed, Calem began to feel ousted from the trio, with Lexi and new companion Valerie (who joined after Lumiose City) often mocking or belittling him. After having a conversation with several members of Team Flare and Lysandre, in The Last Straw, he stormed off from Lexi and ultimately, became a member of Team Flare.
Throughout Invasion, Calem was seen usually with Lysandre, where he began training him to become a better Trainer and battler. He challenged Valerie to a Gym Battle in An Unfriendly Gym Battle in which he won his next Gym badge. He then challenged Lexi to a battle in The Demanding Call!, in which the two exchanged harsh words towards each other.
When Team Flare formally announced their plans to detonate the Ultimate Weapon and Lysandre was revealed as Leader, Calem was seen helping the team with their plans. He and Lexi battled once more in Calem's Revenge!.
As Team Flare's plans intensified, when the battle between Team Flare and Lexi and her friends resulted in Tierno's death, Calem turned his back on Lysandre and Team Flare vowing to get revenge. He then aided Lexi in taking down Lysandre and faced off against Xerneas.
Calem appeared alongside Shauna in A Bond & the Letter, in which it was revealed that he was defeated in his third battle against Siebold for the Kalos Champion title. It was also revealed that he and Shauna were heading to Hoenn together for the next leg of their journey's. Calem also finally admitted his feeling for Lexi, however, when he turned her down and turned down the offer to head to Hoenn with them, he left with Shauna, but not before kissing Lexi.
Calem reappeared in X vs. Y: Destruction to battle in the war. He was apart of the team when they headed into Lumiose City, and eventually when the war officially begins. He ran into the burning building which captivated Lexi and Lysandre along with Marlon, in which he successfully finds Lexi. However, he is unable to save her as she releases her hand, but not before she kissed him back.
Following her death, Calem returned to Hoenn with Shauna.
Calem appeared again in Ruby & Sapphire alongside Shauna and Marlon on their Hoenn adventure. Calem had gathered all but 3 of his Gym Badges from Hoenn; in this time he changed his appearance and became a much more mature and focused battler.
He was seen again in Destinies Align! when he was seen battling against Wattson by May. In Lights On! May vs. Wattson! he is once again reminded of Lexi after Roxanne shows them a picture of her and the Trainer she was searching for, although Calem admits that it would be impossible to be her.
It appeared that after battling at Mauville City he and the others did indeed go to Fallarbor Town for Shauna's Contest, and upon traveling back to Mauville they discovered the issues at Mt. Chimney in Race of Mt. Chimney!. In A Volcanic Showdown!, Calem and the others arrive at Mt. Chimney and help the group stop the destruction of the landmark, before he discovers Lexi is alive and well.
In Aftershock! Calem is shown to be deeply hurt and angry after discovering her to be alive, refusing to speak to her. He eventually does so and confronts her about whether or not the things she did and said at Parfum Palace where true which she tells him they were. He then reluctantly agreed to journey with Lexi alongside May, Brendan, Shauna and Marlon, claiming he was only doing it for Shauna and Marlon. In Keeping Promises!, he and Lexi make their peace for the sake of the group.
From then on, Calem grew closer to Lexi again as he traveled with them. He was shown to have grown much stronger and even given a Mega Ring from Steven and offered a chance to be a Mega Apprentice, much to his happiness. After successfully aiding in stopping Team Magma and Team Aqua, along with the threats of Groudon, Kyogre and Deoxys, he, alongside Shauna, begun their training with Steven to become Mega Masters. He decided to remain in Hoenn to continue his training when Lexi revealed her plans to leave for a new journey. Despite remaining, he told her that she wouldn't have a chance to miss him, as as soon as he completes his training, he'd find her and join her once more.
Gallant Fate[]
Calem returned in the Gallant Fate series. Having completed the Mark of Mastery Exam, Calem headed to Galar with Marlon to meet his family. However, he ended up running into Lexi and her at that point uncontrolled Type: Null, resulting in the group reuniting.
Calem's intention in Galar is to use his new found strength and knowledge to become Champion of Galar, finding out from Nessa how big of an event the Gym Challenge is within the region. He decided to join Lexi for the purpose of learning from her, and training with her. He also decided to not rely on his Mega Evolution capabilities, and wanted to create a whole new team of Galarian Pokémon.
Calem is a confidant for Lexi throughout the journey, while facing his insecurities of his own skills. He manages to excel however, making it to the Semi-Finals of the Champion Cup, only to be beat by Nessa.
Following this, he agreed to head to The Isle of Armor with Lexi to train under Mustard to become stronger. While there, Calem began to discover his true battling technique and style, gaining a great confidence in his time, managing to evolve his gifted Kubfu into Urshifu before leaving it at the Dojo.
Calem in The Crown Tundra utilises his new skills, however a new found rivalry with Silver causes him to fall into old habits often. Despite this, he and Lexi successfully discover the secrets of the Crown Tundra, before an encounter with Darkrai under the command of Team Galactic sends him and Marlon into a deep slumber of which they cannot be awaken.
Awakening Dimensions[]
In Awakening Dimensions, Calem awakes in Hisui in the past alongside Marlon.
Calem's first and foremost thought and drive is to get back to Lexi and make sure she is okay and safe, putting his main priority into finding a way back to her. In this time, while he puts his all into helping the land of Hisui, he hopes his efforts will gain him the knowledge of getting home.
He becomes close to Serena, later revealed to be an early iteration of Lexi created by Arceus. He tries to help her uncover the truth of her origins, alongside finding them both a way to get back home.
As the events of the time-space rift unravel and Calem discovers his way back to Lexi, as the truth is uncovered about Serena and Lexi's connection, he realises his feelings for Serena are linked to Lexi. However, disaster strikes when Serena is struck down by Volo. Serena gifts her Pokémon to Lexi, with her asking Calem to return them to her. He agrees, and leaves through the time-space rift.
Calem awakens and reappears as the team meet Cresselia; its discovered that when he came through the time-space rift, he was intercepted by Cresselia's powers, who Cynthia explained would of most likely been looking for Calem due to being in tune with Darkrai's powers.
Spectral Forces[]
Calem remained with the group to Paldea with his friends, glad to be back in his own time. As he reflects on his time in Hisui, his primary focus became aiding Lexi in whatever way he could, which became vital as her sister Mira was kidnapped by an unknown asailant. As the journey in Paldea took shape, Calem decided to not partake in the Gym Challenge and rather explore and fill up his Pokédex too, revealing his time in Hisui made him appreciate the bond with his friends, all the while building a new team of Pokémon he found intruiging. The journey gained him respect from his friends for his new found growth and maturity.
Calem's protectiveness over Lexi heightened when he began to see her exhibit empathetic like powers towards her Pokémon. Enlisting the help of her grandfather Professor Rowan and newly found researched Professor Turo, he wanted to help gain insight into what was causing her change in abilities. As this progressed, Calem began to question himself and his journey and what it had become. After speaking with both Cynthia and Volkner, Calem realised he had been putting off his own passion for battling in order to protect Lexi. Being convinced by Volkner that he wasn't of any use supporting Lexi currently while he was holding himself back, despite reservation, Calem decided to head off into Paldea to complete the Gym Challenge himself alone. He left Lexi and her friends but concluded that he would return back as soon as possible if she needed him.
