* Admit it, [[HeroKiller General Grievous']] [[EstablishingCharacterMoment intro]] [[NoHoldsBarredBeatdown fight]] [[http://www.youtube.com/watch?v=WIj7gIDFDe4 scared you]]. The [[FamilyUnfriendlyDeath deaths]] of some of the Jedi that Grievous fought were very unsettling. The music playing throughout the fight doesn't help things either. The whole episode was treated like a horror movie, the way Grievous kept vanishing only to pop out and tear someone to bits, the tense music, the way the young Jedi freaks out. It's like watching an animated version of ''Franchise/{{Alien}}'' with lightsabers.
** Oh, and another one of the general's weapons is a chainsaw (we don't see it, but in episode 23, a chainsaw noise, which the director added for horror purposes, can be heard from behind the door where Grievous is fighting a squad of clone troopers).
** Same scene, the short "Montage" of Grievous killing the clone troopers.
** That Grievous enters the scene by crushing a terrified padawan to death beneath him certainly aids the terror.
** the aftermath of it all is quite horrifying to. Ki-Adi Mundi, usually a calm and collected Jedi Master is absolutely hysterical, with wounds all over his body, clearly in shock after his entire crew, him included almost got killed by a nigh-unstoppable killing machine.
** Just as [[TheCavalry the clone troopers arrive]], Grievous knocks away Ki-Adi Mundi's lightsaber and is about to deliver the final blow. [[FridgeHorror If the troopers had arrived even a second later, Ki-Adi would be dead.]]
* Anakin's venture into the cave on Nelvaan gives us [[http://www.youtube.com/watch?v=jwMhX0iWUes this]] rather creepy bit of foreshadowing, as Anakin sees the Story of the Ghost Hand play out before him. It finishes with the helpless hero, his village and family devoured by the Ghost Hand, having an AndIMustScream moment...before the Ghost Hand reforms into the image of ''Darth Vader''.
* In spite of it being a KickTheSonOfABitch moment, the sequence where Anakin falls into an UnstoppableRage and slaughters the Skakoan scientists after witnessing the [[BodyHorror cruel experiments]] on the Nelvaanian males. The [[DeathGlare look on his face]] when he is about to kill them is pure hatred. The reaction of the Nelvaanian's towards the slaughter speaks volumes. The [[FamilyUnfriendlyDeath death of the lead scientist]] deserves special mention. According to both canon and other ''Legends'' stories, Skakoans come from a planet with a high-pressure atmosphere. If their pressure suits were to get breached, they would [[ExplosiveDecompression explosively decompress]]. While the scientist doesn't explode, [[http://vignette2.wikia.nocookie.net/starwars/images/e/e5/Techno_union_engineer_boss.JPG/revision/latest?cb=20110505024410 what happens to him is more visually unsettling than what usually happens to Anakin/Darth Vader's other Force Choke victims]].
* Anakin's rage during his battle with Ventress. The last time he was that angry [[Film/AttackOfTheClones he slaughtered a village.]] It's the same rage that would fuel Vader for ''decades.''
* The Battle of Coruscant shows that the space battle is so full of ships that one of the Confederacy ships coming out of hyperdrive [[RammingAlwaysWorks promptly rams]] into a Republic ship, [[TooFastToStop unable to stop in time]].
* Grievous gives some more NightmareFuel during the Battle of Coruscant; heralding his appearance by stomping across the roof of Palpatine's office. Shaak Ti clearly realizes what is happening and urges Palpatine to come with her. Then the footsteps stop...and just as Palpatine claims that it was nothing, Grievous' head pops into view. It's slightly comical, yet also utterly terrifying.
** It's not the first time that he does this either; after dispatching several Magnaguards, Shaak Ti rejoins her fellow Jedi and reminds them that they have to leave - and the train that was behind her finishes passing, revealing Grievous standing right THERE.
** Then he manages to get to Palpatine's bunker ahead of them and lie in wait, appearing out of the darkness when he ignites his sabers.
