R2-D2 in the Prequel/Clone Wars Era.
Artoo proved his toughness when he was the only astromech to survive the harrowing dash through the Trade Federation’s blockade of Naboo, thus ensuring the survival of both Obi-Wan Kenobi and the future mother of the most famous twins born into the galaxy far, far away. This act of course also assures a chance meeting with Anakin Skywalker. We all know how that turned out.
Artoo’s importance grew throughout the Clone Wars. Anakin, averse to following Republic protocol, refused to wipe the astromech’s memory, making the droid’s databanks vital in the fight against the Separatists. Artoo would also prove instrumental in Anakin’s and Obi-Wan’s rescue of the Chancellor, freeing all three to continue on their paths of destiny… for better or worse.
