Background
B-2-0060 was a normal battle droid for the trade federation during the clone wars. Forced pushed into a deep chasm during a battle many years later it was recovered by scavengers who sold it to Teemo the Hutt. The redubbed 6-Pack was made a gladiator armed with heavy weapons since its main arm blaster was not able to be repaired. After fighting for decades the droid's motivator slowly became more and more damaged. Initially only having the desire to defeat any "Republic Dogs" that were thrown at it in the pit, it began to acknowledge itself as a master of blaster combat, not knowing that most of the scoundrels thrown at were mere prisoners to be executed and not always the best of gladiators.
It assumed that there is more it must master besides combat and begin to admire organic 'repairs', starships, organics
