"Spine Crusher" was a minor antagonist from Rugrats' All Grown Up "Bad Blood" and was a muscular bully who Dill ran afoul of after stealing a video of a (fake) alien autopsy : he appeared very briefly after tracking Dill down and threatened him, unfortunately the tape had been destroyed during a series of unfortunate events at the Pickles' house beforehand and thus the group had made a replacement, hoping to trick him.

This didn't work and "Spine Crusher" decided to beat Tommy up (saying he only beat up the "older brother" in these situations) - however he was scared off by Grandpa Boris and Grandpa Lou before he could do any harm and was not heard off again.
