Ein should get a costume like Jin's hoodie in Tekken 4.
I think this would look really cool on him, especially if the hood is removable.
I do like the idea of a hoodie for Ein/Hayate. I really dont like the hairstyle those guys have and I wish there was a way to cover it.
Speaking of covering heads, I think Baymans helmet (from story mode) should have been optional in-game for his default costume, right from the start. It looks really cool with the goggles and the night vision mount (?) etc.
To be really picky, I also wish Baymans trousers were tucked into his boots for that same outfit, instead of laying over them :/
I was looking at a digital art site the other night and found the below pic.
If Bayman was ever turned into a Fiend, I'd like to think he'd look something like that.
The gash across the chest with the staples in it, is what really reminded me of him.
