When he first sees the busted tires on the Camaro, The Janitor gives a truly awesome sneer. Elvis Presley would be jealous. note Possibly an Actor Allusion, given Nic Cage is a huge fan of Elvis, and played an Elvis Impersonator or wore an Elvis costume in several movies
The Janitor makes a good start to the night by beating Ozzy Ostrich very easily with just a broken mop, forcing him to the ground and pummelling him to a barely-recognizable mess, before ripping the vital circuitry out of his neck to finish him. Without a doubt, the look on Ozzy's face as he realises too late that the Janitor is not some scared, helpless victim is the best part.
Then he brings down Gus Gorilla with his bare hands, a toilet plunger, and a little Bathroom Stall-Fu; slamming him into a mirror before subjecting him to an American History X-style curbstomp against a urinal.
Arty Alligator gets brutally taken down by the Janitor with his bare fists and a textbook Jawbreaker.
And then the Janitor gets handcuffed and has to face Siren Sara and Cammy Chameleon at the same time and does it with ease; putting Sara out of commission by headbutting her to the ground and strangling her with his knees until she shuts down, before snapping off his flexicuffs — possibly through sheer awesomeness alone — and poetically twisting Cammy's head off with her own Overly-Long Tongue.
The Janitor is so badass that you can see the look of genuine fear on the faces of some of the animatronics.
When he finally encounters Willy Weasel, The Janitor faces off with the leader of the bloodthirsty animatronics and kills the bastard; absolutely mutilating him with a duct-taped broom and a bag of unopened soda cans.
Willy actually proves that he deserves his role as main antagonist by utterly thrashing the Janitor in round one, tossing him around and wounding him, until he falls in the ball pit. His mistake, however, is to be content with that instead of dragging him out to finish him. This gives the Janitor the time to come out and grab some weapons for round two. The curb stomp is just as brutal, but this time Willy is on the receiving end; and the Janitor actually makes sure to finish the job by tearing Willy's head off at the shoulders when he's reduced to a twitching, oil-splattered mess.
Finally, Tito Turtle gets comically smashed to pieces by the Janitor and Liv as they drive away into the sunset. Without a scratch to the Camaro.
Liv managing to escape from Tito Turtle, proving she's a good Final Girl.
Escape doesn’t do it justice. After Tito has the presence of mind to unload the shotgun so she can’t just use it to blow him away, she settles for knocking him down and beating the absolute shit out of him with the stock of the weapon, until he's reduced to a swearing, whimpering mess begging for mercy.
That's not all; earlier, Liv also managed to escape from Arty in the vents, Sara in the Forest Room, and was able to keep Cammy at bay long enough for the Janitor to return from his break.
Siren Sara gets hers when she, despite being in a crippled state after her earlier battle with The Janitor, stealthily escapes from the dumpster that she was earlier thrown into (with the rest of the junked animatronics) and uses Tex's discarded lighter and the teens' gasoline to blow him and Jed's car up with them in it (along with herself), complete with a nice Pre-Mortem One-Liner and a sinister reveal of her in their car's rear view mirror as she does so. Considering how many innocent people they helped lure to their deaths inside Willy's Wonderland, it's immensely satisfying to see her give the two bastards their comeuppance.
Tex: (sees Sara in the mirror) Oh,fuck...! Siren Sara: Thanks for visiting Willy's Wonderland. Hope you had a fantabulous time! (the car violently explodes)
