Kingdom hearts:The return of the emperor

After his death in return of the jedi,Emperor Palpatine was sent into the underworld,hades domain,however unlike most of the people who ended up there,Palpatine refused to have what he build be torn away from him,so he would go on to fight through the underworld,and then hades himself,and after a long battle,palpatine won,with him taking away a good portion of hades godly powers,making himself the new ruler of the underworld,and giving him access to the armies of the dead,as well as his old minions,however,while he could freely send his minions to the land of the living,he can only go there briefly,as now he has to find himself a brand new body his spirit can inhabit,that way he can once again rule his empire,and expand it to places he didnt even know existed.
