At first I thought this Aldnoah Zero character looked like a younger Pixis, but upon comparing the images they aren’t similar at all. They’re both just bald and have a mustache.
I’ll just think that they could be distantly related. He’s either Pixis’ ancestor (unlikely coz the world looks far too technologically advanced for the weapons to not have defeated the Titans) or descendant (if so, then the humans had found a way to defeat the Titans and live thousands of years into the future).
After what I just wrote, I conclude that they aren’t related at any way at all and they are just two bald-headed, mustached soldiers from different animes. I think I just wasted my time. Haha.
