Dream was running after Pixelion through a network of dimensions when everything went pitch black. They didn't know it then but, somewhere in the Monster Legends Universe, someone had just closed the Cosmic Portal, changing the rules of the game for everyone. In that moment, Dream got trapped in between two dimensions. The energy wave Corrupted his DNA and he turned into a bug.
After that, Dream managed to get out of the hole between dimensions, but he had to cover his face with a mask, because he looked nothing like his old self. Thankfully, he got to keep his most recognizable trait: his contagious wheezing laugh.
Dream is a Corrupted Earth Attacker with Quicksands and Stun skills. He has an Evolving Trait: at rank 0, he's Hardened, at rank 1, he becomes Immune to Blind and, at rank 3, he gains Precision at the start of every battle.
