The growth of each character in Deep Space 9 is great.
Rom from young boy playing tricks on people on the Promenade
to joining Starfleet
Kira starting angry at everyone thing before mellowing out and
even helping Cardassians rebel against the Dominion
Even Damar
goes from bad guy to leading a rebellion against the Dominion
