Angry Birds X: The Fine-Feathered Movie/Tropes/Nightmare Fuel


 * Baron Harmful being one of the most dangerous and monstrous villains manages to encompass almost everything horrific about the film, from his almost emotionless murder of anyone who stands in his way of getting revenge of the toons, the performance of Tim Curry, the sheer presence of Judge Doom within him, the subtly bonchillingly burning red eyes of him.
 * His voice. Never has Tim Curry ever sounded creepier.
 * Don't even get us started with his One-Winged Angel chimeric form. It's a horrendous mashup of body parts of Golly Gopher, Kneesocks Daemon from Panty and Stocking with Garterbelt, The Cheshire Cat from Disney's 1951 version of Alice in Wonderland, Ren Hoek, Judge Doom, Aku from Samurai Jack, Lord Dominator from Wander Over Yonder, Dark Danny, Stimpy, Pepe Le Pew, Fat Cat, Lynn Loud, Bill Cipher, and Cyborg from Teen Titans Go, both equally unnerving to witness and even more terrifying to watch rampage as a mashup of (mostly) heroic and villainous cartoon characters trying to tear the Angry Birds wing from wing. As if that wasn't enough, his voice is constantly switching from one voice to another, with a combination of some new voice clips and some old archival recordings, including Ren Hoek's Evil Laugh.
 * One of Baron Harmful's Villainous Breakdowns. Imagine, if you will, as his calm composure gets chipped away piece by piece as each of the Flock openly mock him about how he's ironically a toon that wants to commit complete genocide on his own kind for sheer greed and sadism to try and keep him away of the Eggs. First, he gets agressively snappy, which isn't so bad. Then he screams in an increasingly enraged higher-pitched voice that's more like an inhuman screech, "YOU'RE... NOT... EDDIE VALIAAAAAANT!!" and completely loses it, before staring transformed daggers at Bomb, Chuck, and Red with the intent to sadistically kill, becoming more and more unhinged as he speaks? Downright scary.
