Legendary Typings?

I think the lion will be fire fairy (don't ask me why) and the bat will be either dark ghost or ghost flying. Those are just my thoughts and in absolute reality they could be something completely different. In the end we just have to wait and see.

 

It's really hard to say at this point because their designs are very enigmatic, they don't really lean towards one type too much. For the Sun Legendary, it will likely be part Fire-type because of its ties to the sun, and I'm getting a bit of a Psychic vibe from it, as well. I feel like the Sun Legendary is a lot harder for me to interpret, personally. Could be something about its design, it's not exactly 'plain', but more ambiguous. The only thing I can really judge about it is its ties to the sun, and therefore ties to a possible Fire-typing.

As for the Moon Legendary, I'm personally hoping for it to be Dark/Fairy. Fairy-types already have a ton of ties to the moon, and Dark suits its mysterious, almost devilish appearance. It could also be part Ghost, or part Flying, but I'm hoping for Dark/Fairy. It's a new type combination we haven't gotten yet, so it would be awesome to have a main Legendary with that typing.

 

For the Sun legend, I would say it would be a fire-type almost definitely. After all, I think most people associate the sun with fire.
As for the Moon legend, I would assume a fairy type of some sort. There's a trend with the moon and fairies. The whole lore that clefairy came from the moon and a bunch of moves based on the moon like moonblast.
