Toughcatch
this was the nickname given by Gavin Darklighter to his gold and white R2 unit Jawaswag. The name Jawaswag 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 on of them. From that point on, Gavin called it Toughcatch. For ease of use in combat, he shortened the nickname to Catch. Like many R2 units still in service nearly twenty years after the Battle of Endor, Catch was upgraded with the R2-Delta package.
