Sword and Shield still haven't confirm who is the true third legendary.

I see people saying that it's Eternatus mainly because of it's involvement with Zacian and Zamazanta and how all three are involved of the Darkest Day and none can dynamax. However, you have another contender, Calyrex.

Calyrex seems to be a possibility of being the third legendary, espeically since it have the traditional legendary 680 bst (even if it's only available in full power fusion form), compared to Zacian and Zamazanta 670 in Hero form, almost similar to Rayquaza and it's two members. The story was about learning the true royal ruler of Galar and Calyrex once ruled over Galar. It even fought Eternatus considering how it was afraid to be approach with open hands, which is what Eternamax Eternatus looks like. Also, it's a mascot pokemon and since Terapagos was also the a third legendary and it's the mascot of the Indigo disk, why not Calyrex? Finally, if Calyrex is the king, then Zacian and Zamazanta are the royal knights that serves their king.

Who do you think is the third legendary?
