Dark Obsidion is the black-hearted gem of the universe and is the main antagonist of the Legend of Emerald series.


He is as tall as Garnet, heavily muscled with dark grey skin, has black hair that slicks back, and has solid black soulless eyes. He wears a black cloak that has a hood attached to it that he almost always has down as well as a rope sash around his waist. he also has a silver necklace with a black crystal connected to the chain that makes him even more powerful. His gem is located above his heart which symbolizes his black heart.


He is extremely black hearted and extremely selfish. He only cares about himself and is willing to kill anyone no matter how close they were to achive his own goals. He is the kind of gem that would want to watch someone die at his handy work and has no regret for his killings. He does think that Moonstone is really attractive and sometimes hesitates to fight her but most of the time he will never hold back his deadly power.

Dark Obsidion uses things that can torture the mind of others and cause unspeakable pain to others which is exactly what his scythe does. His scythe is made of black magic with has a serrated blade on it that would allow much more pain to an opponent rather than a regular blade. What makes the scythe so powerful is that the staff part of the scythe is bendable and stretchable making him able to strike longer distances and hook enemies with the blade to pull them in. Another interesting feature with his scythe is that he can cause the blade to change its direction allowing it to form into a powerful kwan doo as well as a deadly scythe. Combined with Dark Obsidian's crual tactics and his deadly speed it makes all of his foes literally beg for death.

Fighting style

In battle, he is swift and brutal using his shadow powers and his mind control to cause pain both physically and mentally to his victims. He is skilled at dodging attacks making him almost unhitable and his strikes are extremely swift making them extremely hard to dodge. But when he has someone captured or weakened, he will always try to torture them with his serrated blades to make their death completely inhumane. But if he needs to retreat, he can summon a pair of skeletal wings to fly off or use them in aviary battle.
