The Twilight Thorn is a Nobody that is found in Kingdom Hearts II. It is one of the bosses at the Dive to the Heart. The Twilight Thorn is also the only boss-level Nobody that is not a member of Organization XIII; however, it does share an attack with the most powerful member of Organization XIII, Xemnas.
A Twilight Thorn was featured in a promotional trailer during the early stages of production of Kingdom Hearts 3D: Dream Drop Distance, along with several Shadow Heartless, fighting a Kingdom Hearts-styled Sora in Traverse Town. However, they were ultimately scrapped in favor of the Dream Eaters.
Only one Twilight Thorn appears, when Roxas goes to the Dive to the Heart. When Roxas senses a presence and turns around to see who it is, he briefly sees a figure wearing a black coat before it transforms into the Twilight Thorn, just as Sora, in his own Dive to the Heart, turned to see a Shadow Sora which became a Darkside. Since the player battles the Twilight Thorn as Roxas, they will not receive its journal entry until they return to Simulated Twilight Town as Sora.
The Twilight Thorn is a gargantuan Nobody that seems to be clad in a white bodysuit, as evidenced by the large, silver zipper lining its front. Its simple, round head’s only feature is a white Nobody logo on its front where the creature’s face would be. It has rather thick, short legs with spikes on its hips and long, pointed feet. Its waist is quite thin and has dark grey sides. Its shoulders each sport a gigantic, diamond-shaped spike and its arms are very long, and reach the floor when fully extended down. The Nobody only seems to have one distinct digit on each of its hands, the thumb. They also seem to have high-heels on their ankles. It also has four long, blue tentacles with tips resembling the spikes on the Nobody sigil that wrap around its neck. Its overall body shape seems to be meant to resemble the Nobody symbol. Despite its size, the Twilight Thorn has the same astounding level of flexibility as all other lesser Nobodies. The Twilight Thorn’s name refers to the time of day between sunrise and sunset, which, in turn, references the fact that Nobodies are not truly aligned with the Light or the Darkness. “Thorn” refers to the thorns it can generate as weapons. Its Japanese name, Twilight Zone, highlights its numerous similarities to the Darkside Heartless. Both Twilight Zone and Tales from the Darkside are science-fiction horror serials.
