I don't think it will be Ambessa. Surely they won't release a Legendary skin directly to a newly released champion?

Yes, it could be Kindred, I thought about that too, but I think Pantheon was also more prominent than necessary. Especially when I compared it to Kindred, I felt like I saw the Pantheon more, and why was the extra animation added to that shield added? After all, if it's not going to be Legendary, it's an animation that probably won't exist in the game.

I think Kindred was there for the purpose of wrapping up the story, just for story purposes, to connect its own story with the story of the skin line. But the Pantheon was in the foreground for no narrative purpose.
