He was a bishonen back then, now he towers over Kenpachi Zaraki and looks really scary. I'm betting that if Zangetsu(Quincy) becoming Tensa Zangetsu(Quincy) showed that the younger appearance was stronger, then sometime near the end Yhwach will become younger looking and more powerful. Vollstandig might do that, we've seen weird transformations in the form of As Nodt's Tartar Foras already.
He has black hair, dude.
Quel dommage qu'il ait vieilli
well i guess it shouldn't really be a surprise at this point but he did in fact look like Tensa Zangetsu when he was younger
OOHH I love it, I too made it, my time was 1 hour xD
