this was the nickname given by Gavin Darklighter to his R2 unit. The meant that Gavin believed any Jawa would love to steal the droid. However, when the droid was actually accosted by a group of Jawas, it thwarted their attempts to steal it and actually injured one of them. From that point on, Gavin called it Toughcatch. This name was shortened to Catch for ease of use in combat. About twenty years after the Battle of Endor, Catch was given the R2-Delta upgrade.
