Aren't animation controllers meant to play animations without humanoid?

(meaning if the character has an humanoid it would just ignore the fact that it has one, because it doesn't need one in the first place to play the animation)

So I have this script in my NPC, I run it in studio and nothing plays until I remove the humanoid. But when you remove the humanoid of an character they just turn into this naked, no clothing, no meshes being that I don't even know. 

anim = script.Parent:LoadAnimation(script.Parent.Parent.Swing)
anim:Play()

So to conclude is there a way to play animations without removing the humanoid?
