Dennis Macfield

"Show must go on!"

- Dennis' catchphrase. Dennis Macfield (デニス・マックフィールド, Denisu Makkufīrudo) is a character in the Yu-Gi-Oh! ARC-V anime. He is an exchange student from the LDS Broadway branch and belongs to the Xyz Summon course. In reality, he is actually associated with Academia from the Fusion Dimension. He is one of the Lancers.

Appearance
Dennis has bright red hair hanging down to his chin in crumpled spikes, green eyes, and a beauty mark below his right eye. He wears an odd ensemble of clothes, a long-sleeved blue collared shirt with a purple tie around his neck, and an orange jacket on top of that missing the right sleeve and with a shorter coattail, as well as a black glove on his left hand, and dark pants and red shoes. He keeps his Academia pin hidden under his collar.

Personality
He is a well-rounded and charismatic type of character and has a sense of humor, yet can also be serious at times. As an admirer of Yūshō Sakaki he runs a Deck that seems to mirror his and Duels as an Entertainment Duelist, thus he is often flashy and enjoys performing acrobatics. When excited, he seems to be rather air-headed and tends to forget about anything else at the moment, as seen when he wanted to talk to Yūya since he is the son of Yūshō and enjoyed his Dueling, only to be interrupted in the still ongoing Duel by the Ryozanpaku School students' offensive, forcing him to block their attempts at damage while showing comical frustration at their interference.

Despite his penchant to gather attention to himself as an entertainer, he does not seem to mind sharing the spotlight since he took the opposing attacks himself in favor of Yūya doing the honors, believing him more adequate for "the finale".

After he is revealed to be associated with Academia, his personalities doesn't seem to be any different, unlike Sora Shiun'in. He demonstrates a degree of regret when Halil and Olga encountered him and Yūri, as he knows what Yūri will likely do to them, but at the same time, makes no move to stop him or the Obelisk Force. He pragmatically avoids his identity Being compromised during the Battle Royal and internally panics when he thinks Reiji Akaba has found him out.

Maiami Championship Arc
Dennis made it through the preliminary rounds of the Maiami Championship, getting into the Top 16.

Battle Royale
He joined 14 of the other contestants in the Stadium for the announcement of the Battle Royal section of the tournament, where they were told that they would need to collect Pendulum Monsters to progress. Dennis saved Yūya Sakaki from defeat by Ryozanpaku School's Ken Umesugi and Makoto Takeda. They quickly bonded over their admiration of Yūya's father, Yūshō Sakaki. He encouraged Yūya to continue and win the Duel and helped him over his fear of entering Berserk Mode with "Dark Rebellion Xyz Dragon", which ultimately helped him win the Duel. Dennis parted ways with Yūya later and waited in the Volcano Area to Duel Yuzu Hīragi. He at first was cornered by Yuzu's Bloom Diva, eventually won by turning her ace monster against herself with Magic Card "Trick Box". Right before Yuzu fell into lava, Dennis saved her with Trapeze Magician who returned to his Field due to Trick Box's effect. As he wished Yuzu luck in the tournament and received her Pendulum cards, Serena arrived and, mistaking Dennis to be the Xyz remnant, challenged him to a Duel. Dennis agreed to Duel, believing it necessary as an experience for Entertainment Duelist.

Throughout the Duel, Dennis tried to be entertaining despite the fact that Serena was continuously serious and he decided no to perform Xyz Summon as to not cause further misunderstanding. When he finally decided to be more serious, he unluckily drew "Fusion" and realized he couldn't win, so he merely Set a monster and a face-down card, which infuriating Serena who thought Dennis was underestimating her. As Serena switched his monster to Attack Position and attacked it, Dennis prepared to activate his face-down but was distracted the arrival of the Obelisk Force and lost.

Although defeated, Dennis pursued Yuzu and Serena and eavesdropped their plan to switch clothes and find Shun Kurosaki. Yūri then arrived, prompting Dennis to say that he was "tired of waiting". Dennis told Yūri of the girls' plans and then set off to find Yūya. He met Yūya in the Jungle Area, where he feigned surprise of the alternate dimensions knowledge. He joined Yūya and Noboru Gongenzaka to find Yuzu. They searched in the Iceberg Area, where Dennis falsely determined that Yūri had completed his mission. He split later and instructed the Obelisk Force to capture Serena, Shun, and Tsukikage.

When the Battle Royal ended, Dennis kept Mieru Hōchun safe and claimed he had only found her when Yūya asked him if he had found Yuzu. He was present when Reiji Akaba told them of his plan to form Lancers and watched his subsequent Duel with Yūya. He planned to take Serena back to Academia once events quieted down but was unable to once she revealed herself to the rest of the Lancers to be a Duelist from Academia. He was both impressed and shocked to learn of Reiji's skill in multiple Summoning techniques, having been informed by Gongenzaka, Shingo, and Yūya. He was surprised to hear Reiji has seen what happened to Yuzu, panicking that Reiji might have found out his true identity.

Departing to Synchro Dimension
Dennis, along with the other members of Lancers were called by Reiji to gather at LDS, where Reiji revealed that they will go to Synchro Dimension to recruit new allies to fight against Academia. Serena then revealed that Yuzu was also in Synchro Dimension with Reiji had witnessed Yuzu disappeared with a Synchro Dimension Duelist, shocking Dennis who had thought Yūri had captured her. With the card that Reiji has provided, they departed to the Synchro Dimension.

Duel Against Gongenzaka
When he and Gongenzeka realized they were separated from the other Lancers upon arriving, they attempted to ask the residents if they have seen their allies with no luck. However, Dennis cleverly used magic tricks in an attempt to attract attention which was successful when they got a TV reporter's attention. He decided to entertain the crowd further by dueling Gongenzeka where he deployed Pendulum summoning and Xyz summoning which astonished the crowed due to never seeing either summoning methods. After Gongenzeka proceeded to defeat Dennis with his Synchro summons, they were approached by a rich man in a limo named Gallager.

Underground Riding Duel
Dennis and Gongenzaka were taken to an underground Riding Duel. While Dennis was excited, Gongenzaka was wary of Gallager, insisting to Dennis that they should not follow him, but Dennis only told him not to be wary so much. When they watched the Duel, they were shocked to know that Shun was a participant. Shun explained that he went along with the Duel to determine strong Duelists that can be recruited for Lancers, but was disappointed that none of them match his expectation. Gallager revealed that if they go through with the underground Duel, they may qualify to enter Friendship Cup where they can Duel the King of Duel, Jack Atlas. Convinced that there will be many strong Duelists in the tournament, Dennis decided to participate in underground Duel so he can enter the Friendship Cup, but Shun persisted that he will be the one to enter, leading Dennis to challenge him to a Riding Duel that will determine between the two of them who will enter the Friendship Cup.

Duel Against Shun
Dennis was able to fight in an even ground against Shun with the combination of his Pendulum and Xyz Summons, much to the latter's shock. Dennis capabilities and strategy caused Shun to question is he really from LDS and learn that kind of Duelling style from the school, to which Dennis answered by feigning ignorance of Shun's suspicion and continued their Duel while declaring he will win the Duel. Once the two reached 100 LP each, their Duel were forcefully stopped by the Securities who then arrested them along with Gongenzaka and several Commons.

Dennis, Gongenzaka and Shun were all sent to the Facility. Shun was sent to solitary confinement on the first day, leaving just Dennis, Gongenzaka, and two other inmates in their shared cell. After Gongenzaka bribed a guard into preventing the inmate from being bullied, Dennis used his cards to bribe the dinner server to ensure that the inmates got enough to eat. Yūya, Shingo, and two Commons, Crow Hogan and Shinji Weber, arrived in their cell on the next day. Dennis explained their capture to Yūya. He later joined Gongenzaka in urging the group to calm down after being bullied. Dennis was present during Yūya's Duel against Chojiro Tokumatsu, the "boss" of the prisoners, and expressed shock at Tokumatsu's tactics.
