Dennis Mcfield

Dennis McField, spelled Dennis Mackfield in the Japanese version, is a character in the Yu-Gi-Oh! ARC-V anime. He is an exchange student from the Leo Institute of Dueling School for the Performing Arts (Broadway campus in the Japanese version) and belongs to the Xyz Summon course. In reality he is associated with the Duel Academy from the Fusion Dimension. He is a former member of the Lancers.

Appearance
Dennis has bright curly 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 bow tie around his neck, and an orange jacket on top of that missing the right sleeve and with a shortened hang on the right side, as well as a black glove on his left hand, and dark pants and red shoes. His unique clothing with two different sides possibly foreshadows his actual task as a double agent, working for both the Lancers and the Academy. He keeps his Duel Academy pin hidden under his collar.

During Turbo Duels, Dennis wears an orange and grey jumpsuit with a maroon helmet.

Personality
Dennis is described as a well-rounded and charismatic individual with a sense of humor, yet can also be serious at times. As an admirer of Yusho Sakaki he runs a Deck that seems to mirror his and Duels as a Dueltainer, 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 Yuya since he is the son of Yusho and enjoyed his Dueling, only to be interrupted in the still ongoing Duel by the Bandit Warrior Academy students' offensive, forcing him to block their attempts at damage while showing comical frustration at their interference. This doesn't, however, prevent him from being distracted when he spots the Obelisk Force while attempting to make a move in his Duel against Celina. 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 Yuya doing the honors, believing him more adequate for "the finale". This sense of modesty is also seen after his defeat against Shay Obsidian, where he admits that Shay won.

After he is revealed to be associated with Duel Academy, his personality remains largely the same, unlike Sora Perse. Dennis demonstrates a degree of regret when Halil and Olga encountered him and Yuri, as he knows what Yuri 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 that Declan Akaba has found him out. Despite this he was still willing to work with the Lancers in stopping Duel Academy, possibly in order to keep his cover.

Dennis truly enjoys being an entertainer, and seems to like spending time with his fellow Lancers. Nevertheless, he is loyal to his dimension's cause and despite knowing the consequences, he green-lit the Invasion of the Xyz Dimension after discovering Lulu.

Despite this, he can be just as cruel and sadistic as several Duel Academy agents, vowing to destroy Shay slowly before his second Duel with him began. He showed noticeable annoyance and anger at Shay for "taking off his mask" as the Duel progressed, and after being forced into a corner, Dennis reveals his true colors and his usual cheerful tone becomes more maniacal while declaring it a "Hunting Game".

After his final defeat, he is approached by Yusho, who says that his Duel brought a lot of smiles, and he can bring more if he rejoins the Lancers. Dennis, feeling guilty for his betrayal against the Lancers, refused. But he is still a good loser, fulfilling Kite's demand as well as Rin's location. As per his loss, he cannot return to the Professor, and carries out one last thrilling show by carding himself.
