It is unknown how 1242 dies it is most likely of natural causes though

Personality and traits
RC 1242 was a republic commando he also hated the geonosians to heart and he disliked the Jedi for using him and his brothers to do they're work for them. He would (even though very rarely) have times where he would get very angry mostly at the end of geonosis because he had just lost a brother right before geonosis was over.
