If you could pick any fictional animal to be your lifelong companion (like a Pokémon or fantasy pet), what would it be?

I di not like pet or animal in my hone because they may harm kids or snall children and may cause dirt and diseases. In my opinion, responsibility of raining animal or pet is very big and I am not interested to keep animal or pet in my home.

Animal or pet may be dangerous for any individual mainly for babies or small kids. They dirt home and may causes several diseases. So I am not interested in any fictional animal in my hone. I live happily with my family members.
