Ushio and Tora/YMMV

Complete Monster - Hakumen no Mono qualifies, and how (apart from being, well, literally a monster). Personally and through its various spawn and underlings, its hobbies include bringing down countries from within, stealing a newborn baby for dastardly experiments, and of course just plain killing stuff.
- See here for a fan-spliced example with Kirio's 'mother'. The fiend!
Crowning Moment of Awesome: So very many, but I think the weak Izuna, when told things would be decided in a battle, and he was the only one not locked up, all but immediately said, "Okay, where's my opponent?!".
Crowning Moment of Funny - The very first episode, when the then-unnamed Tora asks Ushio to free him from the spear. Ushio asks what Tora intends to do, and Tora replies that he'll eat him first and spread terror among humanity, heheheheHAHAHAHA~ooooooooowwwwwwww!!!! as Ushio starts stomping the spear deeper. And then he slips up and repeats the SAME THING when Ushio gives him a second hearing! Youtube here. Tora really can be a moron at times...
Crowning Moment of Heartwarming - The story arc with the snow-girl who falls in love with a human man... And her mother who lost her own.
- Ushio and Tora also qualify! When the bakemon Kuin mocks Ushio's weakness, stupidity and lack of training compared to its master Kirio, Tora beats the crap out of it, then says to Ushio: "I don't know why I got really p*ssed off when he was saying that crap about you... BUT I still hate your guts!"
High Octane Nightmare Fuel - "I really wanted this hair....and these lips, too!"
- And then this.
Tear Jerker - Lots, see Complete Monster entry for just one example. A good deal of the Bakemono in the story are given quite sad backstories.
- One in particular is the death of Hizaki Mikado.
- And don't forget Minoru's father.
- The part where either Asako or Mayuko must sacrifice herself to make a new Beast Spear that has everyone crying, even the bakemono who don't really want to do it either but have no other recourse. The whole arc becomes one long tearfest as important characters one by one vaguely recall someone who touched them Ushio and Tora but because of an enemy's attack, can't remember exactly who and why.
The Woobie - You will want to give Tora AKA Shagakusha a hug once you learn his backstory. Same goes for Hyou.
- So, SO many characters.
  - Some of the bakemono enemies even, though it doesn't excuse their reaction of massacring all humans they meet.
Uncanny Valley - So, Our Monsters Are Weird yes... Now add assorted limbs, faces and even naughty bits that look COMPLETELY like an ordinary human's on almost random places on the bakemono's body, and it gets even freakier. Examples: A perfectly bad-ass looking crab bakemono which is then revealed to have HUMAN FACES on the inside of its claws; numerous lesser bakemono with mutiple HUMAN ARMS AND LEGS instead of more practical for fighting claws.
