Darth Maul's Family-Unfriendly Death also counts. Seriously, that dang image of him falling down the reactor shaft...
In The Clone Wars, Darth Maul survived that experience. Imagine going through that and no one comes to help you until YEARS later after you have gone almost completely insane. Family unfriendly indeed.
In the climax when the Nabooean pilots make off in their recently-liberated fighters, one of them takes a hit from a gun turret and loses an engine, plummeting helplessly to a fiery crash in the valley below. Imagine what those last moments had to be like for the pilot.
Darth Sidious. Just his very presence is enough to give one the chills. In a stark contrast to his Large Ham performance in Revenge of the Sith and Return of the Jedi, Sidious is very serious and no nonsense here, giving the Trade Federation threatening messages and blunt orders of murder and mayhem upon Naboo. His hooded appearance makes it impossible to see the upper proportions of his head, giving the impression of an inhuman Eyeless Face. Not counting his public appearance or his one scene on Coruscant, Darth Sidious only appears as a hologram for the entire movie, making him look like a phantom. It becomes even more unnerving when one realizes that the secret identity of Darth Sidious is the Senator of Naboo and newly elected Supreme Chancellor, Palpatine, putting the seemly kind and noble politician's actions under a new dark light.
When Obi Wan and Qui Gon sneak up to find a battle droid army preparing for the invasion, there seems to be a eerie noise not unlike the kind you would hear in a haunted house. What doesn't help is that this same noise was recycled in TARKIN'S debut in Rebels.
When the battle droids begin marching towards the Gungans, you realize exactly why professional armies run marching drills: all those hundreds or even thousands of feet rising and meeting the ground in perfect unison gives you an idea of just how massive the Trade Federation's army is even though only a few of the droids are in view at the time, and it'd be downright frightening if you were standing on the other side of the field from them. Stamp, stamp, stamp, stamp comes your doom.
Darth Sidious's answer to Nute Gurney's request regarding to Gungan Army amassing near the swamps: "Wipe them out. All of them."
