I'm trying out things in the workshop
Bh stands for brick-hill, I had to shorten it bcuz it was too loang

In the normal legacy workshop, you would have to build the avatars manually.

Brick-Builder does have an avatar maker tool as long as you can find the userID of the avatar you want.

The last and final way (and my personal favorite) is to script a bot (fake player) into your game you can even make it move and talk if you wanted to

example script:
