So the day wolf and the werewolf are just different forms of the same Pokemon, but they don't change form?
That's kind of dumb, why not just make them separate Pokemon at that point? Might as well make Silcoon and Cascoon forms of the same Pokemon...
Well this was a weird trailer. "Type: Null" is its name? Why can't they give it a real name? And why is it called Type: Null if it's Normal-type with just a regular everyday ability?
And a jellyfish monster that's apparently not a Pokemon... what is going on
I'm also leaning towards the theory that the evil team(s) will want to use the legendary to create eternal day/night. Which is honestly very reminiscent of Groudon vs Kyogre. All land vs All water, and now All day vs All night.
