It is one of the possibilities of the future of "Link Joker", who seek harmony with Cray guided by "Messiah". It is able to seal its opponents' power temporarily using "Lock", derived from a theory different to that used by the invaders of planet Cray in the past. In addition to the power of Lock, Big Crunch Dragon combines the "alteration of gravity" and the "conversion of atoms' kinetic energy" by using its mana to manipulate power more strongly for a longer time. The power sealed by Lock can be further converted into its comrades' power. Instead of immobilizing and dominating others, this dragon seems to use Lock for the purpose of defense and energy supply.
Though they possess great power, they use it in a way different to those in the past. Pure power involves no good or evil. Depending on its users, power can bring either invasion or harmony.
