Soublades is a bipedal, humanoid Pokémon. Its body is primarily black, with blue colorations on its head, arms and legs. Its head has sharp pale blue "ears" protruding from either side, and has a fire burning above it that resembles the plume on a knight's helmet. Its eyes have pink irises and wisps emanating from its white pupils. Almost all of Soublades' body is covered in an old dark purplish blue suit of armor, filled with grudges. A plate with three pink indentations on its center covers Soublades' face. Instead of hands, Soublades wields purple-cyan blades created from both fire and ghost energy — specifically, the lingering regrets of the deceased. These blades can grow into great swords in battle, increasing Soublades' power in the process. Soublades is merciless and will do anything to win a battle. It prefers to do close-quarters combat, with a mix of sneak and surprise attacks. By using its quick speed to locate a foe's blind spots, it will then move closer before slashing them with its large swords. Any cuts from Soublades' swords will cause wounds that leak life energy, which the swords then absorb.
