Jaden Yuki

Jaden Yuki is the protagonist of GX, who fused his soul with Yubel in the third season. Since Miracle Synchro Fusion is post-GX, this character is thus both Jaden and Yubel, fused into one. Duel Links named this fusion "Jaden/Yubel". Any mentions of Jaden/Yubel will refer to this fusion as one person, but since Jaden and Yubel still have a bit of separation between themselves, as we'll discuss later, Jaden and Yubel will also be referred to separately, as separate people.

In this AU, the fusion as one person is referred to as Jaden.

Jaden/Yubel, Chazz, and Jesse live in a two-bedroom apartment. It is a one-floor apartment, the bigger bedroom used by the trio and the other bedroom being a guest room most often used by Leo and Luna.

## Soul Fusion

In season 3 of GX, Jaden fused his soul with Yubel's, and they became one person. This person mostly has Jaden's appearance, but his eyes can glow like Yubel's, and he's grown taller and his hair is longer; this could be just natural growth, but this growth is never shown between school years, let alone a school year, so it may be a result of fusing with Yubel. Season 4 and Bonds Beyond Time prove it's not a complete fusion, however, as Jaden and Yubel talk to each other as separate people. Jaden can still summon Yubel in duels and fuse them with other monsters, but if Yubel is sent to the graveyard, he is supposedly alone.

Jaden and Yubel's "control" of Jaden/Yubel is never a static thing. It's never 50/50 or just combined. Sometimes Jaden is more in control, sometimes Yubel is more in control, and sometimes it really is just a combined fusion between the two. The difference in control isn't always something controlled by them, though at times it is, as shown when Yubel took control of Jaden/Yubel while Jaden was asleep so Yubel could eat some healthy food in The Ultimate Nightmare. In instances of the fic where one is more in control than the other, Jaden is still referred to as Jaden, while Yubel is referred to as Yubel, even though Yubel's appearance is still that of Jaden/Yubel, who mostly takes on Jaden's appearance.

The difference in fic between Jaden and Yubel can be difficult to spot, especially from outside perspectives, which are common. From Jaden/Yubel's perspective, if Yubel is speaking to Jaden, at all it's probably Jaden, and if not, it's probably Jaden/Yubel.

Vrains allows users to customize their avatar, but the default behavior is to retain their true appearance. Vrains doesn't interpret this as just how the user looks when logging in, and is somehow able to interpret Jaden/Yubel as the fusion of Jaden and Yubel, and adds more of Yubel's features to Jaden/Yubel's avatar. Jaden/Yubel's avatar's eyes are described as having a color that is hard to decipher, like the color is constantly changing, or his eyes are trying to be multiple colors at once. His hair is a bit longer than usual, his clothes are a bit rattier than usual, and his teeth are more like fangs. Under his jacket sleeves, but imperceptible with it on, his arms are scaly.

## Abilities

Jaden/Yubel has all the abilities of both Jaden and Yubel.

Jaden/Yubel, as the reincarnation of the Supreme King's soul, wields the gentle darkness. They have heightened luck, the connection with spirits, and are destined to fight the Light of Destruction. They have the abilities of the Supreme King, and can summon an aura of darkness that strikes fear into those around them. They are the Supreme King of Dark World, and continue to rule over Dark World despite spending much of their time outside of Dark World, They can see, understand, and talk to spirits. Jaden/Yubel's eyes can turn gold, either when the Supreme Kings corrupted soul has taken over them, when reminiscing and regretting their time as the Supreme King, when they are at a low point/rock bottom, or when accessing the Supreme King's fear-inducing aura.

Jaden/Yubel have Yubel's abilities as well, notably the ability to transfer between dimensions and the ability to summon spirits physically to the human dimension. This is easiest using their duel disk, and most monsters can only be summoned that way, but Yubel is the easiest to summon and thus sometimes can be summoned without it. They can see through illusions, sense the approach of danger (or at least darkness-related danger), and sense when people are hiding nearby. Along with typical fanon ideas, Jaden/Yubel can transform their own appearance and summon Yubels wings and claws. Yubel's wings, when not summoned, appear to be like tattoos on Jaden/Yubel's back. When using Yubel's abilities, Jaden/Yubel's eyes glow orange and green, just like Yubel's do.

All souls are made of a combination of darkness and light;Jaden/Yubel (as well as Jaden on his own) is an exception. Their soul is 100% darkness and 0% light.
