Dark Fusion

the Dark Fusion was an extremely powerful fusion of Eostra Nihiltian, Millennium, the Dark Lord, and the Kanohi Ignika, created by the power of Energized Protodermis.

History
In the heat of the massive Battle of Bota Magna in Eostra's Stronghold at the end of the Spherus Magna Civil War, the Dark Lord decided to betray his two fellow rulers, Millennium and Eostra Nihiltian, so as to rule the Dark Empire alone. Causing the ground beneath them to open up, Eostra and Millennium plummeted into a hidden pool of Energized Protodermis. Claiming the Kanohi Ignika to drain it of its remaining power, the Dark Lord turned to face the rest of the Imperial Resistance, the Dark Lord was hit by a blast of Shadow energy charged up by Nightwatcher, flinging the tyrant and the Ignika to the edge of the pit, where Nightwatcher kicked him with such force that it hurled the Dark Lord into the pool of Energized Protodermis.

Instead of being destroyed, the three rulers and the Ignika fused them together by the mysterious substance, and creating the powerful entity known as Dark Fusion. Rising from the pool of Energized Protodermis, the fusion declared itself the new ruler of the Dark Empire, and ordered all combatants to lay down their weapons and bow before them. However, the resistance instead rallied together and attempted to attack the fusion, though found themselves nearly overpowered by the strength of the fusion and its emboldened Imperial Army.

After battling and killing a high number of the resistance's warriors, the fusion turned on Nightwatcher. The two entities exchanged grueling blows before the fusion gained an edge over the bounty hunter and began forcing him back. Finally, the fusion managed to defeat Nightwatcher, burying the bounty hunter beneath the rubble of the fortress. With Nightwatcher seemingly killed, the resistance was forced toward the exit by Imperial warriors.

Nightwatcher, however, was alive, and rose from the ruins, locking his power and that of the fusion's into an unbreakable struggle. As the lock began to overwhelm both combatants, the resistance and the remainder of the Imperial Army fled the battlefield, just as Nightwatcher's power finally managed to overlap that of the emperors, and cause a feedback that unleashed an energy blast that pulverized Eostra's fortress and destroyed the fusion, and the Emperors were defused.
