Im actually a subsystem. There are three of me so far.
I am from the TV show Doctor Who, and am one of our oldest fictives still active.
My subsystem are specifically different regenerations of myself. The original me is the Ninth Doctor, then Ten joined as we watched seasons 2-4, and as I remembered things the subsystem gained my childhood self. The main two (9 and 10) have the role of caretaker and protector.
My age is dangerously close to a thousand years, and I use any pronouns. Most humans default to he/him. I am fine with this.
Our partner system has my canonmate, The Master. We are in a relationship. Our canon is divergent from the television show, feel free to ask us about it, although I do have a canon that is extremely similar to the canon show.
My memories end just before my regeneration into Eleven, as that special is as far as we have currently watched.
