Can you tell which of our current heroes has graduated to the World Cup?. Guess who!.
It is almost certainly Anubis. I was looking at him and destroyer, and here is reason. First, some pics
Both of them have 3 toed feet, which other heroes of similar build don't have. However, Destroyer has spikes on his forearms which almost certainly would've shown in that shadow. He also has horns and spikes on his back, which seem more prominent than shadow shows. Anubis has ears and headdress "ribbons" that are smaller and appear to match the extrusions on the shadow's head.
But if it is new skin, then it could be Destroyer... but then who really wants a Destroyer skin?
