Film: Poor Henry Bowers. In the final act of the film, he falls under the influence of Pennywise. He kills his father with a knife, then proceeds to track down the Losers. Just before Mike can climb down into the sewers in the basement of the Neibolt house, Henry pulls him back and nearly kills him. Mike is too quick, however, and ends up pushing Henry down the well. He presumably falls to his death. I mean, it seems like a pretty long way down.
Novel: Henry's story is much more interesting in the novel. Much like the movie, he's under the influence of It. Instead of attacking at Neibolt, though, he follows them into the sewers with his two lackeys: Vic and Belch. With a trio of new potential victims, It turns into Frankenstein's monster. It decapitates Vic and destroys Belch's face. Having watched both of his friends die, Henry Bowers goes insane and gets lost in the mazes of the sewers. He eventually washes out and gets blamed for the deaths of all the missing children. Henry gets locked away in a mental institution for 27 years . . . until It returns and helps him escape.
