as the name states, depicts a 3-headed dog-like monster named Cerberus spitting flames. Two of the heads represented by the colored plastic underneath the transparent casing are located on one side, while the third is located on the opposite side. Theoretically, this would leave the Energy Layer unbalanced, but in reality the effect is so minuscule that it shouldn't be considered a fault in competitive play. Kerbeus' rim has 16 protrusions, with half of the protrusions being larger. In theory, this characteristic would grind the opponent's Layer, but in reality it has the reverse effect and that makes it prone to loss by Out-Spin and the uneven surface adds recoil.
