>>10299376He hasn't even been teased, and he'd be a Mattel Creations figure, so...
Let's start with pic related. There's 23 figures here (counting centaurs as beasts), 3 of which are from the Lost '88 wave and are getting either mass retail or at least exclusive release. That leaves 20 other teases. So far, only 1 box art tease has become an MC release, Frog Monger. Other MC exclusives have included vintage figures (Grizzlor, technically Wun-Dar), a vintage foreign variant (Kamo Khan) and an Filmation OC who hadn't been teased on box art (Kol-Darr).
So if Origins only lasts through 2024, I'd say his chances are very low. If it lasts long enough to sell another few dozen MC exclusives, maybe 40%.
