Caboose is one of the Blue Team's soldiers from Red vs Blue. He is the only one who knows how to drive Shiela, although, in an act of a team-killing F**k-tard, killed Church.

It was later found out that Church killed Church, although Caboose was still known as a team-killing f**k-tard.

Caboose was also responsible for discovering a talking bomb named Andy, constantly sucking up to Church, and naming an alien Fluffy, the alien that only loves.
