The Iron Giant (1999) ending / spoiler
Once the nuclear missile is launched, the Iron Giant sacrifices himself to save the town of Rockwell, Maine by flying into space and colliding with it before it reenters Earth's atmosphere.After his presumed death, a statue is built in his honor. Hogarth is now friends with the kids that bullied him; Dean and Annie are now a couple (married?). Hogarth discovers a stray bolt from the giant's remains, but it reactivates and makes its way (along with all the giant's other parts) to a glacier in Iceland, where he is self-reassembling.
