One of King J-Der's primary weapons, and the only one that cannot be used by J-Ark. Fired from cannon barrels forming each of King J-Der's fingertips, powerful beams lance out in concert to deal heavy damage to whatever they strike. Unlike KouRyu, whose MASER cannon has a lightning-style beam, King J-Der's Maser Cannons are coherent beams. Always fired in either Five-Linked (all of the cannons on one hand) or Ten-Linked (both hands) configuration. King J-Der usually uses its left hand for Five-Linked Maser Cannons.
Pia Decem PIT has the ability to deploy Maser Fighters, which are distinguishable by their blue color. These reproduce the effect of Maser Cannons when they strike an enemy.
