In 21 BBY, Crasher was in charge of a unit in the Clone Youth Brigade, which was infiltrated by Boba Fett, who wanted to assassinate Mace Windu because he killed Boba's father, Jango Fett. Crasher brought the cadets to a shooting practice with Fury, and Boba was the best. He didn't notice when Boba left the group afterwards, and sabotaged the ship's engines. He left in an escape pod to save his life. He also reported to Mace Windu and Anakin Skywalker that one of the cadets' pods were missing, and the Jedi found it, but after Boba Fett had left.
Crasher was not seen with armor, but instead, he was seen with a uniform on. His uniform had a small utility belt on it. It was red with a light blue-gray vest on top. On the top of his sleeves, he had two clone emblems. He also had an insignia on his vest.
Sergeant Crasher had a rather different haircut than most of the clone troopers. He had a receding hairline, showing that he was older than most of his brothers and representing his wisdom and experience he had.
