Armored Ventus Nightmare

The Armored Ventus Nightmare is the final boss of Kingdom Hearts 3D: Dream Drop Distance.

Kingdom Hearts 3D: Dream Drop Distance
When Riku travels to Sora's Dive to the Heart, the Nightmare Armor appears out of the darkness and engages him in battle. Upon the Armor's defeat, the darkness covering Sora and his Keyblade cracks and fades away, leaving a comatose Sora behind as he falls into a pool of darkness.

Design
The Armored Ventus Nightmare is Sora clad in Ventus's Keyblade Armor, which is now black in coloration due to the Darkness corrupting it. Due to this, a Nightmare Dream Eater has possessed it, making the emblem of its version of the species appear on the visor. The boss wields Sora's Kingdom Key, which is also colored black, with a reverse grip; Ventus held his Keyblade like this.

Abilites
Because it is Sora trapped inside, this Nightmare has all his skills and his Keyblade. It incorperates Ventus's own fighting style as well, making it a fast and tricky opponent to defeat.
