taken from wikipedia ... Though the Sith Order was believed to have destroyed itself, Palpatine was the last in a long line of surviving dark lords. While it is unknown when he became a Sith Lord and took the name Darth Sidious, it is known that his master was Darth Plagueis. Plagueis is thought to have been capable of manipulating midi-clorians to create life and avert death. He was murdered by Sidious in his sleep. ... now what about sidious becoming hideous ? loved the piggy-back by chewwie ha ha ! & thought Sidious saying Vader would take care of business was great as well LOL !
