Aleph and Hosts

What hosts do the Aleph aspects embody? Many of the Aleph character images I have seen show them with pink glowing eyes and seams in their “skin” implying artificial bodies. Do all aspects have these bodies, or can they look absolutely human?

I think, there would be aspects with a complete human appearance like the recreations (Joan of Arc or William Wallace) for Infiltration purposes.

Makes sense to me.

Aspects have the perfect look for what they do. If aleph want to show a smug superiority aspect look like top models with neon in their eyes. If she/he/it want to make you relate, they will look 100 % human.
