Commander Cody gets killed by Genral Grevius.It is a part never ever shown in star wars.Obi Wan and Commander Cody went to fight Genral Grevius and Genral Grevius stabs Commander Cody.I found out from Leo Star Wars #1 That can't be canon because Commander Cody gives the order to shoot Obi Wan Kenobi when Order 66 comes in. Plenty of things get taken out, such as Shaak Ti's death in Episode III aboard General Greivous' ship. (I believe her canon death is during The Force Unleashed at the hands of the Apprentice).
