""There's no escape this time, Basil!"
- Felicia, whom Ratigan keeps tame by keeping her well fed. Possibly the only example in a Disney movie where someone is eaten on screen and doesn't come back afterward.
- Ratigan during the final confrontation in the clock tower. His clothes are torn, he's given up all pretenses at civility, and at several moments is scurrying about like a real rat. And it is terrifying.
- Ratigan's savage beating of Basil tops them. We see this previously friendly crime boss tear his cape, run through a maze of gears to get to Basil, knock him from some roof on Big Ben onto the hands of the clock, leap down at him, tearing him with claws, throwing him around, etc... and then there are the sounds of pain Basil expresses. It's no surprise that an image of Ratigan during his fight against Basil was the No-Holds-Barred Beatdown trope image for a while.
- Not to mention that, unlike their battle of wits where they're more or less on equal footing, Basil stands no chance against Ratigan at ALL in a physical fight, since Ratigan is a sewer rat and Basil is just a mouse. If Ratigan hadn't been taken down by the bells ringing, he would have torn Basil to shreds.
- Or worse. In real life, wild rats frequently eat mice.
- The beginning where Olivia and her father are having a nice moment, when someone tries to break down the door to get inside the store. Then the father hides Olivia in a cupboard and Fidget comes and we see the silhouette of Fidget beating up Olivia's father!
- Both of Fidget's jump scares, at the beginning and when he pops out of the baby carriage.
