Dark Thorn

The Dark Thorn is a minor villain in the video game; Kingdom Heart II. It's a Pureblood Heartless, as well as the true, and much more powerful form of the Shadow Stalker.

History
After Sora, The Beast and their friend dealt enough damage towards the Shadow Stalker, the chains on it body began to fall off. As a result the Shadow Stalker began to mutate and transform into it's ture form; the Dark Thorn. In this form, Dark Thorn loses it's ability to possess object in the Beast's Castle, but it does gain a few other abilities, including becoming invisible. However, Sora was able to use the very elements that the Heartless had recently possessed to beat the Dark Thon into submission. The Heartless then fades back into darkness, forcing Xaldin to retreat and reform his plan.
