MegaDarknessBagramon (Fusion)

DarknessBagramon is the final form of Bagramon, the primary antagonist of Digimon Xros Wars, after absorbing his brother DarkKnightmon.

Appearance
In his new form, save for his head and enhanced right limbs, Bagramon's body is covered in black and gold armor modeled after DarkKnightmon. Bagramon's left horn becomes golden and enlarged while two of his remaining red horns shrink away. His eight wings are also enlarged into twelve.

Description
As D5 begins, having abided his time until this moment, DarkKnightmon makes his move and literally stabs Bagramon in the back before using the Darkness Loader to absorb his brother and obtain his power. However, Bagramon metaphysically destroys DarkKnightmon and takes control over the fused body while reconfiguring it in his image. Destroying Shoutmon and sending the rest of the Xros Heart United Army into the void, DarknessBagramon takes his leave to enter the human world.
