Make a 3D Character glow?

Hey, all. So I have an alien dud with a very human form and I need him to glow from head to toe, hand to hand. A light source should also show off his ability, but I don’t want the light blocked by his arms. I have another glowing one with wings, and again, I don’t want the arms or wings blocking the light- but I want other objects to not pass through the glow. Has anyone else done something like this?

I am not sure if I get your question correctly, but it looks like Emissive Materials is what you’re looking for. This video gives you a quick idea on how it works.

I didn’t have to use Rim Lighting, exactly. I just had to put the bad guy on his own layer. Thank you, everyone, for the help.
