It's up to you what makes them unconventional, so I won't limit anybody by itemizing a list of things that make a character unconventional in my opinion. Let's just see something that would (hopefully pleasantly lol) surprise people.

My female lead from "Crystal Blue" is a muscle princess, which I think is pretty rare for female leads across the board. Even when female characters are very strong, female leads are rarely given a lot of visible muscle, and female characters with a lot of muscle are often slotted into a tomboyish space, which while fine sometimes, doesn't always have to be the case.
