- Ass Pull: A self admitted one about Darth Gravid, who only exists so that the current Sith don't have knowledge they need.
- Can't Un-Hear It: For many who've listened to the audio-drama, Daniel Davis IS Darth Plagueis.Jensaarai 1: "This is what Darth Plagueis sounds like. This is his voice. This is Darth Plagueis speaking."
- Complete Monster: Palpatine's backstory as a villain shows how much of a Manipulative Bastard he truly is, as we see him working with the Trade Federation to plot the blockade that takes place in Episode I. It is revealed that he killed his own parents and siblings, and is incapable of feeling regret when committing heinous actions and various misdemeanorssuch as when he ends up crashing his landspeeder and killing two people without any remorse on his part. When Darth Tenebrous foresaw Palpatine's future murder of Plagueis upon his death and possession of Plagueis after the latter betrayed him, he was noticeably horrified at not only Plagueis's murder at the hands of his apprentice Palpatine, but at how evil Palpatine is, even for the Sith.
- Hilarious in Hindsight: The fact that Palpatine refuses to go by his first name is much more amusing in light of the bemused reactions many fans had to learning that his Canon first name is Sheev.
- Fridge Brilliance/Fridge Horror:
- In Revenge Of The Sith, Palpatine says that "[Plagueis] had such a knowledge of the Dark Side, he could even save the ones he cared about... from dying". Now wait a second, just whom could a Sith Lord ever actually care about? Oh, his test subjects...
- Though, considering he was willing to destroy a Sith tradition just to share the universe with what he saw as a son, maybe the guy just loved easily.
- Another bit is why Plagueis is compelled not to mention the name of Kamino in front of Jocasta Nu - that's because, as it turns out, she's the librarian that dismisses Obi-Wan's claims about the archives in Attack of the Clones - if she knew about Kamino, she would've been aware of Dooku's sabotage, and likely undone the Grand Plan then and there.
- Moral Event Horizon: Palpatine crosses this fairly early on by killing his entire family and takes up permanent residence beyond its border.
- Narm: "Gravid". Seems good if you're going for the connotations of "grave", but less impressive if you know "gravid" is the equivalent word to "pregnant" for egg-bearing animals (and in some languages it just means pregnant). Darth Laying Hen?
- What Do You Mean, It's Not Political?: Much like the Prequel Trilogy, people have tried to read into this book to find political beliefs they agree with.
YMMV / Darth Plagueis
