Fiver
this early-model R7 astromech was owned by Anakin Solo. The name "Fiver" came from the five attempts Anakin made to upgrade the notoriously poor-functioning droid to the standards of an R2 unit. As Anakin became more and more involved with the fight against the Yuuzhan Vong, Fiver was not given a regular memory wipe, and developed its own personality. Fiver became much more independent, and was invaluable in Anakin's escape from the Yuuzhan Vong on Yavin 4.
