He called the Federation President and organized a task force to hunt down Bad Vader and the Klingons. Captain James T. Kirk transported Good Vader up to the USS Enterprise NCC-1701 and warped to Sherman's Planet. There Kirk beamed down with Good Vader and tried to make Kral talk.

Bad Vader set a trap and when Kirk arrived, Bad Vader was waiting for him. Bad Vader used blue Force lightning on Kirk and was just about to finish Kirk off
