In the fourth season, Jaden battles against 'Nightshroud' who preys on everybody's negative emotions and wishes to engulf humanity into his Darkness Realm.

He bares a great amount of guilt for all the misfortunes his friends and others had to go through and finds himself trying to distance himself from others. He no longer finds dueling fun and wishes to only duel when he needs to.

He is described as someone who is 'not human.' After his time in the alternate dimension and his fusion with Yubel, Jaden's original happy and easy going personality turns serious and aloof. Afterwards, he has gained the powers of both the Supreme King and Yubel with the ability to make duel monsters come alive, see visions of the future, resist supernatural powers (such as hypnosis) and the ability to generate wind. In order to fulfill the prophecy and cleanse Yubel of her corruption caused by the light, Jaden decides to fuse himself with Yubel. After being released from his possession, Jaden learns that he is the reincarnation of the Supreme King and that Yubel, a duel Monster that was the Supreme King's guardian and the mastermind behind the alternate dimension, is bounded to the Supreme King by prophecy. While in an alternate dimension, Jaden falls into despair after seeing his friends sacrificed and becomes possessed by the Supreme King, a ruthless and merciless ruler and the original wielder of the Gentle Darkness. In the third season, Jaden and his friends are transported to an alternate dimension where duel monsters are real. The Gentle Darkness also gives Jaden special powers such as the ability to communicate with Duel Spirits, most often conversing with Winged Kuriboh, a card he received from Yugi Mutou on the day of his entrance exam. It also is revealed that Jaden possesses an ability called the Gentle Darkness, a power that was created to balance out the light. In the second season, Jaden fights against the Society of Light, a cult like organization that wishes to brainwash the world. In the first season, Jaden's excellence in dueling lead him to become one of the Spirit Key holders, a responsibility given to the best duelists in the school, who are meant to guard the Spirit Keys from the Shadow Riders who wish to resurrect the Sacred Beasts. Despite his excellence in dueling, he is placed in the Slifer Red dorm due to his below average grades and overall disinterest in anything that is not duel-related. He is shown to be a very talented duelist as he is seen beating out some of the toughest duelists such as Professor Crowler, Chazz Princeton/Jun Manjoume, and various others. He is described as an energetic, passionate and optimistic boy who comes to Duel Academy to learn to become the new King of Games.
