Ronald Tyler, played by Jeremy Sylvers, is a character in the film Child's Play 3.
Ronald is a young private boy who befriends Andy Barclay at the military school he is sent to after failing to cope with living at several foster homes.
When he finds Chucky (who mailed himself to the same military school to go after Andy again), he decides to go after Tyler instead. At first, Tyler finds Chucky to be a nice guy, but realizes the true colors of the doll's evil murderous ways once he attempts to transfer his soul into his body much like he attempted to do with Andy in the first two films.
Ronald, with the help of Andy and Kristen De Silva, manages to escape Chucky when Chucky is destroyed in a giant fan in an amusement park funhouse ride.
