Aura Man

designated under the serial number DKN.000, Aura Man was created by request of Gadget with the help of his old science teacher, Dr. Kracaw and Dr. Light himself. Gadget brought Aura into being with the hopes that he would unlock the very ability to use his will as a weapon and defeat Execrator, the .EXE which cursed the shattered worlds, once and for all.

Aura has the unique ability to control emotional energy and can weaponize it or use such abilities to help others via putting them in a more desirable mood. Aura however cannot control thoughts.

Of course, Gadget does not view Aura as a weapon.
In fact, Gadget knew that he had to give Aura a reason to fight, or he would ultimately fail.
so, Gadget decided to take the role of father figure in order to form a strong bond with Aura.

Aura has since grown very close to his father, and he forever treasures the saber he had given him.
