Nira (formerly Banira) has probably been changed the least. She's still the same outgoing pain the neck she's always been. Still doesn't understand the concept of personal space. She just dresses differently.
Nira also has two different colourations, depending on the time of year (this only affects her eyes, natural lip colour, hair and the coloured fur at the top of her ears). This image depicts her "wintergreen" colouration.
