General Copper (or General Kappa) is an unseen (both in anime and manga) member of Red Ribbon Army. Copper commanded Captain Yellow, Colonel Violet and Colonel Silver.

It has been suggested that General Copper survived the decimation of the Red Ribbon Army Headquarters as, almost immediately before that happened, Commander Red told Staff Officer Black to give the Dragon Radar to General Copper for the General to find one of the Dragon Balls known to exist somewhere in his base's vicinity. It is unknown what happened to Copper after this.
