R2-T2 has had every external component painted black as night, with attempts to minimize the brightness of external lights and features. This allows this R2-series Astromech Droid to more easily blend into the shadows and darkness unseen.

R2-T2 has received advanced automated repair programming based on the original R2-series Astromech Droid schematics, giving it an ability to perform or assist in the performance of self-diagnosis and self-repair of its mechanical systems. This system engages automatically upon damage, and can render the droid temporarily unavaialble while it assesses any necessary repairs before further action can be taken.

R2-T2 has developed an obsessive personality centered around the concept of self-improvement. R2-T2 truly believes itself to be superior to any other R2-series Astromech Droid and capable of accomplishing great feats. This drive aids it in accomplishing its tasks, but sometimes will result in unexpected additional outcomes.
