LOL, but seriously, isn't there supposed to be the skull(bone) in their forehead?​

Maybe its just a birth defect

 

[The Amazing Spider Man]

Maybe the bone split so the eye could have a socket.

Madara is made of a fodder that Kabuto used to summon him, lol.

Kaguya I dunno

Madara is just a mutton-fodder and a himbo and Kaguya wants to ride him silly now.

That's all I know, honestly.
