I really hope it's not used as a bad guy I want it to be a wise ancient species or something.
Backstory of species: It was an endangered species in scratch 1.0 originated by a cube with but emotions and eyes with a scratch user. They married and created this class. But over time evolved and created the national weapon the sacred sword of block sworn to keep it away from all other species. Because if they turn it over to whoever wishes for it, either the creature or user and the sword will both both be destroyed, or the creature or user will be blinded by the darkness and will slay everyone in their path. Once the wish of darkness is granted the user, or creature will be destroyed. The sacred sword of block can strike lighting on it's end! And move at the speed of wind!
