Ultraseven. Im sorry, it's the holes on his eyes (I know why theyre there but couldnt they at least retcon it by redesign?).
Even the Ultra-act has it. Eww.
The odd thing is, the original UltraSeven suit really kinda downplayed the eyeholes. Infact you couldn't tell they were there part of the time.
After that though, they seemed to be exaggerated. I think it's just part of his character by this point, because he still had them in Seven X, despite getting an entire new design.
I've seen others with similar eyeholes lose them in other adaptations-such as in some manga and anime, Taroh will lose his eyeholes- but not Seven.
*Shrug*
As for me?
I love V3. I really, really do. His character is awesome, his show is awesome, everything is awesome.
He is the ugliest fucking Rider I have ever freaking seen though.
And I'm not a man who thinks that Riders look all that great in general.
Seriously, nothing about his costume works, except maybe his scarves but by that point you're just PRAYING for something.
The Next version didn't help it at all.
