I'll take the riddle making turn.

People believe most of us to vile,
Yet we are often misunderstood,
Hiding in fear because of that,
A Knight helps us remember that we are human.

Terrible is our futurist cousin for her wish,
Angelic is our current cousin bravely standing,
Pleasant is the pseudo-mentor of our current cousin,
Our ancestor is the only male version we know today.

Do you know who our cousins are?
Can you guess what we are called?

The riddle has a theme which is the answer.
