For example, when Rex is thrust into a different fictional universe like Middle - earth from The Lord of the Rings, he has to deal with the different cultures, languages, and ways of life.

Rex recognizes Luke as Anakin's son and decides to share his experiences of the Clone Wars with Luke, teaching him valuable lessons about war, loyalty and the Jedi.
Another theme is the struggle with identity. Since Rex is a clone, he often has to figure out who he is beyond being a soldier. Fanfictions like 'Rex's Self - Discovery' focus on this aspect, showing his journey to find his own place in the galaxy.
