I see... and I think I get what was going on. "Sonic Forces: Speed Battle" is most likely spin-off/play-for-fun game that related to Sonic Forces, which is the main game of the series.

Ergo, that was the reason why the SEGA's official characters couldn't have the renders of Speed Battle in their infobox, but they were allowed to be in their galleries.

And also, you're right - as I have noticed the difference in Zavok's artworks - it's the position of his tail. And for Cream's render, it was just her with Cheese thrown in the picture, but nothing else that was difference from her original one (which you put back in after undoing my edit).
