Quirkless Tenko/Shigaraki - Tumblr Posts

(Edit: we didn't realize that this theory was actually quite old and that this has been talked about before but I digress) This is entirely speculation but you know how Tenko's hair got lighter (almost white) and his eyes became red when his Decay quirk activated for the first time? Before that, both of them were black.

If the Dad for One theory is true, AND if Izuku was born with the Decay quirk as some theorize, it could have been that this quirk-related appearance passed down to him by his father could have just been yoinked along with his quirk, hence this fellow ^ right here looking like that. AFO's eyes, at least, could be a side-effect of his main quirk (All for One), since they're quite different from Yoichi's and they're twins (this only is an argument if they're identical twins, that is). With how often Izuku is compared to AFO and Tomura being compared to All Might/Yoichi in the source material, it just makes me wonder if Izuku, unknowingly, was actually a villain in Tenko's story. Being spared having Decay, he got the chance to become a hero just like Tenko dreamed of when he was a child (with his grandma being a hero as well), while Tenko was condemned to the destiny of a villain that was supposed to be Izuku's fate by birthright.
