Obsidian

Obsidian is a Black Diamond Dragon, One of the rarest of all dragons. He is a Black Diamond dragon, and only one will ever exist in the entire universe. After it has been born, no other Black Diamond dragons can be born. An old man is after it, claiming it is his. The old man has properties similar to that of The Blob, a frozen creature in the antarctic.

After Bolt died, he reincarnated into Obsidian. It hatched deep in the caves, where it was discovered by a group of explorers, including Dark Knight, Raot, Joyee, and Kryru. The bolt that was in Bolt's shoulder got drilled into it's back. As of now, it's just a baby.

Obsidian is usually shortened to Sid. He displays amazing powers for having been born not too long ago. He cannot die of age.
