YMMV / Tommy Taffy

• Complete Monster: The titular Tommy Taffy is a doll-like man who forcibly inserts himself into families' lives. Ostensibly there to help people raise their children as a "third parent," Tommy responds to any resistance to his presence with savage beatings. Angered at attempts to get rid of him, Tommy retaliates with further violence, going as far as to burn down an entire neighborhood on one occasion. Other notable incidents include Tommy forcing a broken broom handle down a man's throat and impaling him through the stomach while making the man's family watch; stuffing a little girl's mouth full of thumbtacks as punishment for phoning the police; and dangling a baby over a running garbage disposal. Tommy also has a habit of raping women who don't comply with him and playing mind games with parents by exhibiting sexual aggression towards their young children, knowing that the parents won't try to stop him for fear of incurring his wrath further.
• The Woobie: The families Tommy infects. Being subjected to Tommy's abuse is shown to have lasting psychological effects and effectively ruin their lives.
