Methods of forming an electrode for use in a plasma arc torch are provided that generally include forming an electrode body defining a proximal end portion and a distal end portion, forming a recess within the distal end portion, securing a slug within the recess of the distal end portion, creating a bore through the slug and the distal end portion of the electrode body, and securing an emissive insert within the bore. In another form, a hybrid electrode is provided, which is formed by the manufacturing methods of the present invention, and which includes an electrode body defining a cavity, a secondary body secured to the electrode body, and an emissive element secured within the bore and in contact with the secondary body and the electrode body, wherein the secondary body is not exposed to the cavity.
