Take the all party members except atton far away attack some innocent guy like the czerka guy trapped in the old military place on telos or the clerk at the desk in the bumani exchange corp office, and atton will take a liking to u
"Revan" was Revan's name, so If they were known as Revan and the Exile, they would know Revan's name, but not the Exile's. The exile's name, is, by the way, Darth insano. After all, Kreia did say, psychotic urges were all that drove him.
If they were my characters, revan would be a dark side soldier/jedi gaurdian and
the exile would be a jedi gaurdian/sith maraurder, they would both wear the heaviest armor available and both use double-bladed lightsaber.
The exile would win, because revan was limited to lvl20 in the version of the engine kotor 1 used, but u can reach level 50 in this version, so the strongest revan can be is lvl 20, and the strongest the exile could be is level 50, so the exile would win!
