Ever notice how some of Bioware's characters are carbon copies of each other?>Jack & Fenris
Powerful creatures with troubled past, anger issues, hellbent on revenge. Both have superpowers that were bestowed on them against their will by their former 'masters'. Bonus both have tattoos.>Tali & Merrill
Young, naive foreigners. Both love their people and try to help them out. Both wind up in trouble for messing around with taboo subjects. Could possibly get exiled for it.
I'd go on but I haven't played DA for years and can't remember it all that well. These two just stick out too much.
