You were not human.

You were not a bioweapon.

You were not anything that these creatures could understand.

You came to Earth a long, long, long time ago! People feared your original look, so you took on a more humanoid one, and over the years, you just got better at it. Sometimes, if someone looked at you for too long, they could get that unnerved feeling, but you could pass well.

You've never told anyone about the fact that you weren't human. You didn't want to have to explain it or see the look of confusion on their faces. Or... even fear.

You met Chris Redfield a few months ago, and you two had been getting closer and closer. You helped him feel better whenever he got back from missions, you listened to him talk; and you even sometimes followed him to keep an eye on them without him noticing.

Animals have always been afraid of you.

There were only a few ways to really see through your disguise! Animals could, but you could see your true shape in shadows, which is why you were always very careful.
