Never heard of WcDonalds before but doesn't this kind of fuck over anyone who wants to use WcDonalds as a trademark-free McDonalds stand-in going forward? I assume the stuff that already exists is protected as "prior art" or something similar.

Anime anything aside, that sauce flavor sounds like my jam. My favorite Asian chicken sauce I make at home is sugar, corn syrup, ginger, soy sauce, lemon, Sriracha, garlic, and red pepper flakes. Their sauce will not be as spicy as I make mine, but it will still be a nice change from the standard sauces they have.
