Meet Rebornica.
Rebornica is a space entity(not created by myself) and if you search 'Rebornica' or 'Space Entity' pictures of him are likely to show up.
He technically doesn't have a gender, but I'm going to call it a 'him' to make things easier.
Now imagine if Sam was a space entity. I get there are a lot of things wrong with this idea, but hear me out. This isn't a theory or anything just a what if sort of thing.
So what I imagine is when Sam puts on the helmet, he basically becomes a space entity underneath the suit. Hence the glowing and the white eyes and such. I really like this idea and want your thoughts on it! Below I'm going to put a few more pictures or different versions of Rebornica. NONE OF WHICH ARE MINE! Links to pictures are below!
BASICally he's just stars and galaxies in the form of a human(kind of) and I think he looks cool! THE LAST ONE IS MY PERSONAL FAVORITE
No idea if they match or are in order/ they are there so no one yells at me!)
