Ultima Weapon 'Reversed Union'

This is the Counterpart Keyblade, based on the Darkness and the reversed Medals.

The blade is based off the Legendary X-blade, which pretty much wasn't seen in this Game yet, so it was my inspiration to get to this Design as near as possible, mainly because the X-blade is the inspiration that Keyblades exist in the first place, the filigrane Ornament is showing reversed to symbolize Darkness. As a "X-blade" substitute I have angled the Nova Burst Button to 45° and decorated it with the corresponding Gems of this Game, Moon, Power, Speed and Magic. 
The Keyblades teeth are the Emblem of the Book of Prophecy, decorated with the Demon Wing Part, the Token is a modified Dark Matter and the Guard is based off the Reverse Medal Design.

My biggest thanks go to Jun, makaihana975 for his inspirational Artwork, which gave me enough muse to work out those powerful beasts! Without him and his support those weren't be here right now!

I hope you guys like it!

P.S.: And if this question would interest someone:
This Keyblade doesn't Level Up in the Traditional way as all other Keyblades, rather it takes all 5 Slots of each Keyblade and adds them up to determine the strength of each individual slot.
The catch is, this Keyblade only counts the Reversed Slots, but as more powerful all other Keyblades are, this one will have the best perks and profits from it, so if you want Ultima to be powerful, then get your Keyblades to be powerful as well! 

Well the best example I have are the Summon Conditions of the Winged Dragon of Ra in Yu-Gi-Oh!, if you catch my drift.
