Sparky first appeared in the 1999 novel The New Jedi Order: Dark Tide I: Onslaught, the second book in the series Star Wars: The New Jedi Order and the first installment of the Dark Tide Duology.
Although described as an R5 unit in Onslaught, The New Jedi Order: Balance Point, and The Complete Star Wars Encyclopedia, in The New Jedi Order: Dark Tide II: Ruin, Sparky is mistakenly described as an R2-series astromech droid.
